## Product Description
This is a generic bezel/crystal gasket for the Rolex Lady‑Datejust 179174, measuring 21.3mm and made of nylon as an O‑ring. It creates a watertight seal between the crystal and the bezel, helping the watch maintain its original water resistance. When the original gasket has hardened, cracked, or failed, this aftermarket part offers watchmakers a cost‑effective replacement solution.
## Features & Function
- **Material**: Nylon – offers excellent wear resistance, oil resistance and ageing resistance, outperforming ordinary rubber.
- **Dimension**: 21.3 mm (likely inner or outer diameter – compare with the original before installation).
- **Compatible model**: Rolex Lady‑Datejust 179174 (26mm case, Caliber 2235 movement).
- **Function**: Fits between the sapphire crystal and the bezel (or case); compresses to fill the gap and prevents moisture and dust from entering the movement.
- **Aftermarket advantage**: Significantly lower cost than genuine parts, easy to source for repair.
## FAQ
**Q1: Which is better, nylon or rubber gaskets?**
A: Nylon offers better ageing and oil resistance but is less elastic. Rubber is more elastic but ages faster. Rolex uses nylon gaskets in some references; this product follows the original specification.
**Q2: Can I install the gasket without silicone grease?**
A: It is highly recommended. An ultra‑thin layer of waterproof silicone grease helps the gasket slide into place without twisting and improves the seal. Skipping it may make installation difficult or cause leakage.
**Q3: Can this gasket be used on other Rolex references?**
A: Probably not. Different Rolex models use different gasket sizes and cross‑section profiles. Use only for the 179174 or after verifying dimensional compatibility.
