This is a high‑quality generic replacement sapphire crystal for the Breitling Chronomat Evolution reference A13356, measuring 32.7mm (diameter) × 3.8mm (overall height) × 2.55mm (edge thickness) with a domed round profile and anti‑reflective (AR) coating. Made of synthetic sapphire glass (Mohs 9), it offers exceptional scratch resistance and excellent optical clarity, serving as a direct substitute for a damaged or scratched original crystal.
Material: Synthetic sapphire (Mohs 9), highly scratch-resistant, resistant to daily wear.
Precision dimensions: 32.7mm diameter × 3.8mm overall height × 2.55mm edge thickness – designed for the Breitling Chronomat Evolution A13356 case (typically 43mm diameter).
Profile: Domed round – thick edge and large‑radius dome, offering good impact resistance and a vintage sporty look.
Optical performance: Features anti‑reflective (AR) coating, reducing glare and enhancing dial readability, especially in sunlight.
Q1: How to tell if the crystal has an anti-reflective coating?
A: Tilt the crystal under a light. A blue or purple reflection indicates AR coating; a white or pale yellow reflection means no coating. This product features AR coating.
Q2: Will the watch retain its original 300m water resistance after replacement?
A: Due to tolerances in generic parts, the original 300m rating cannot be guaranteed. Always perform a pressure test (10 bar minimum) after installation. For daily use, consider it 100m splash‑proof.
Q3: Is a gasket included with this crystal?
A: No. Purchase a matching round gasket (approx. 32.7mm ID, 0.8‑1.0mm cross‑section) separately, and apply a thin layer of silicone grease before installation.
