It is designed to replace front watch crystals or case back glasses for a wide variety of watch models. Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. ## Features & Function - **Material**: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. - **Uniform thickness**: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. - **Diameter range**: 16.5mm – 45mm, covering common sizes from small ladies‘ watches to large sports watches. - **Profile**: Flat round – completely flat surface, no curvature. - **Optical performance**: Usually uncoated (AR coating available upon request – consult seller). ## FAQ **Q1: How to choose the correct diameter?** A: Measure the inner diameter of the case’s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05‑0.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. **Q2: Can this crystal be used as a case back (exhibition back)?** A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. **Q3: Is the 2.0mm thickness suitable for all watch cases?** A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. **Q4: Can I order a crystal with anti‑reflective coating?** A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. **Q5: Can I replace the crystal at home?** A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker. ## Why Choose SOFLY Watch Parts? - Fast worldwide shipping within 3 business days. - Competitive pricing on Seiko/Hattori calibers. - 3,000+ watch movements and parts in stock. - Trusted by watchmakers worldwide. - Personalized sourcing support via **info@soflypart.com** or WhatsApp **+86 18620212114**. ##### Our Popular Items [![Cartier Tank 2415 Mineral Crystal](https://www.soflypart.com/wp-content/uploads/2022/04/DSC08929.jpg)](https://www.soflypart.com/product/generic-cartier-tank-wsta0042-4322-sapphire-crystal-18-9mm/) ### [Generic Cartier Tank WSTA0042/4322 Sapphire Crystal 18.9mm](https://www.soflypart.com/product/generic-cartier-tank-wsta0042-4322-sapphire-crystal-18-9mm/) [![Rolex 4130 Mainspring](https://www.soflypart.com/wp-content/uploads/2020/12/DSC05891.jpg.webp)](https://www.soflypart.com/product/generic-rolex-caliber-1220-1225-mainspring/) ### [Generic Rolex Caliber 1220/1225 Mainspring](https://www.soflypart.com/product/generic-rolex-caliber-1220-1225-mainspring/) [![Rolex 4130 Mainspring](https://www.soflypart.com/wp-content/uploads/2020/12/DSC05891.jpg.webp)](https://www.soflypart.com/product/generic-rolex-4030-mainspring/) ### [Generic Rolex 4030 Mainspring](https://www.soflypart.com/product/generic-rolex-4030-mainspring/) [![Rolex 4130 Mainspring](https://www.soflypart.com/wp-content/uploads/2020/12/DSC05891.jpg.webp)](https://www.soflypart.com/product/generic-rolex-2030-2035-mainspring/) ### [Generic Rolex 2030/2035 Mainspring](https://www.soflypart.com/product/generic-rolex-2030-2035-mainspring/) [![](https://www.soflypart.com/wp-content/uploads/2026/08/Cartier-caliber-191-mainspring.jpg)](https://www.soflypart.com/product/cartier-caliber-191-mainspring/) ### [Cartier Caliber 191 Mainspring](https://www.soflypart.com/product/cartier-caliber-191-mainspring/) [![](https://www.soflypart.com/wp-content/uploads/2026/08/ETA-E03.001-4000-Circuit-Block-Electronic-Module.jpg)](https://www.soflypart.com/product/eta-e03-001-4000-circuit-block-electronic-module/) ### [ETA E03.001-4000 Circuit Block Electronic Module](https://www.soflypart.com/product/eta-e03-001-4000-circuit-block-electronic-module/) [![Zenith El Primero 18.0240.4021 Crystal](https://www.soflypart.com/wp-content/uploads/2022/07/DSC09824.jpg)](https://www.soflypart.com/product/generic-zenith-el-primero-chronomaster-02-0310-400-sapphire-crystal-29-85mm/) ### [Generic Zenith El Primero Chronomaster 02.0310.400 Sapphire Crystal 29.85mm](https://www.soflypart.com/product/generic-zenith-el-primero-chronomaster-02-0310-400-sapphire-crystal-29-85mm/) [![Breguet Classique 8067 Sapphire Crystal](https://www.soflypart.com/wp-content/uploads/2022/04/DSC09612.jpg)](https://www.soflypart.com/product/generic-breguet-classique-5920-5907-sapphire-crystal-30-5mm/) ### [Generic Breguet Classique 5920/5907 Sapphire Crystal 30.5mm](https://www.soflypart.com/product/generic-breguet-classique-5920-5907-sapphire-crystal-30-5mm/) [![Hattori VD54/VD53 Circuit Block Electronic Module](https://www.soflypart.com/wp-content/uploads/2024/03/Hattori-VD53-circuit.jpg)](https://www.soflypart.com/product/hattori-vd55-vd57-circuit-block-electronic-module/) ### [Hattori VD55/VD57 Circuit Block Electronic Module](https://www.soflypart.com/product/hattori-vd55-vd57-circuit-block-electronic-module/) [![](https://www.soflypart.com/wp-content/uploads/2026/06/ETA-caliber-2000-1471-stop-pinion.jpg)](https://www.soflypart.com/product/eta-caliber-2000-1471-stop-pinion/) ### [ETA Caliber 2000-1471 Stop Pinion](https://www.soflypart.com/product/eta-caliber-2000-1471-stop-pinion/) - [![Omega 9300 Reversing Wheel](https://www.soflypart.com/wp-content/uploads/2024/08/Omega-9300-reversing-wheel.jpg)](https://www.soflypart.com/product/omega-caliber-9300-reversing-wheel-7229300a32037/)Quick View [Add to Cart](https://www.soflypart.com/product/omega-caliber-9300-reversing-wheel-7229300a32037/)Watch Parts [

It is designed to replace front watch crystals or case back glasses for a wide variety of watch models. Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. Features & Function Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches.

However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. Features & Function Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

It is designed to replace front watch crystals or case back glasses for a wide variety of watch models. Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. Features & Function Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

It is designed to replace front watch crystals or case back glasses for a wide variety of watch models. Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. Features & Function Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it.

It is designed to replace front watch crystals or case back glasses for a wide variety of watch models. Made of synthetic sapphire glass (Mohs hardness 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal. Features & Function Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear. Uniform thickness: 2.0mm fixed thickness, easy to stock and manage, suitable for most standard case groove depths. Diameter range: 16.5mm \u2013 45mm, covering common sizes from small ladies\u2018 watches to large sports watches. Profile: Flat round \u2013 completely flat surface, no curvature. Optical performance: Usually uncoated (AR coating available upon request \u2013 consult seller). FAQ Q1: How to choose the correct diameter? A: Measure the inner diameter of the case\u2019s mounting groove (or the original crystal diameter) with calipers. Select a diameter 0.05\u20110.10mm smaller than the measurement to allow room for adhesive or gasket. For example, if the measurement is 30.0mm, choose 29.90mm or 29.95mm. Q2: Can this crystal be used as a case back (exhibition back)? A: Yes. As long as the size matches and the thickness fits the case back groove depth, it can be used as a case back glass. Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness.

However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.

Note that case back crystals usually do not require an AR coating and need a matching gasket. Q3: Is the 2.0mm thickness suitable for all watch cases? A: Not necessarily. Measure the thickness of your original crystal first. 2.0mm is a common standard thickness for many Swiss and Japanese watches. However, if the original thickness is 1.5mm or 2.5mm, using 2.0mm may cause installation difficulties or sealing issues. Always verify the original thickness. Q4: Can I order a crystal with anti\u2011reflective coating? A: Yes, custom coating is available. However, coating will increase cost and lead time. Please discuss your requirements with the seller before ordering. Q5: Can I replace the crystal at home? A: If you have a crystal press and relevant experience, you may attempt it. However, sapphire crystals are brittle and can crack under uneven pressure. Inexperienced users are strongly advised to entrust the replacement to a professional watchmaker.
