Applications & Features:
--- Watch lenses are an important part of watches. Choosing the right lens material and style can improve the quality of watches. For daily watches, watch lenses with good scratch resistance and wear resistance are a good choice.
--- The lens is transparent, light, and shatterproof, and is also suitable for formal occasions, business occasions, and outdoor activities.
--- The round watch lens is made of good sapphire, which is harder than glass, has good wear resistance, corrosion resistance, and is durable.
--- The flat lens design has high transparency and durability, is not easily affected by scratches, and maintains clarity for a long time.
--- The edge of the watch mirror is smoother and more delicate, which improves the overall appearance texture. The relatively smooth edge reduces the possibility of direct force and helps reduce the risk of scratches.
--- Easy to install and replace, and damaged ones can be easily replaced. Very suitable for watch repairers to repair watches.

Useful Tips:
--- The lens diameter tolerance is ±0.05mm. Please use a caliper to measure the diameter/thickness before purchase. Never use tools with lower precision such as soft rulers, rulers or measurement software for measurement.
