product details

Our double‑domed sapphire watch crystals are precision polished from high‑quality synthetic sapphire. Both top and bottom surfaces feature curved domed profiles, delivering elegant three‑dimensional appearance. With Mohs 9 hardness, they possess outstanding scratch resistance, high light transmittance and reliable impact resistance, offering effective protection for watch movements against dust, moisture and external damage.

Regular diameter ranges from 20‑40 mm, smaller or oversized sizes are available for customization. We support full customization of thickness, dome curvature and edge finishing based on your drawings or samples. Multiple coating options such as anti‑reflection, anti‑fingerprint and anti‑glare coatings can be applied to upgrade optical performance. As direct manufacturer, we offer competitive factory prices for sample trials and large‑volume orders. Every piece passes strict dimensional and visual inspection to guarantee consistent batch quality. Global B2B inquiries and sample orders are warmly welcomed.
