Upgrade your Seiko diver or GMT build with our latest generation of premium sapphire crystals. Designed specifically for the SKX platform, these crystals combine durability, clarity, and aesthetics to give your watch a truly refined appearance.
Each crystal features a double-domed profile with either a Clear AR or Blue AR coating applied to the underside. Clear AR minimizes unwanted reflections while preserving the natural color of your dial, unlike Blue AR coating, which can alter the overall look. Because the AR coating is applied to the underside of the crystal, it is protected from everyday wear and scratching.
The carefully machined smooth beveled edge creates an elegant transition between the bezel insert and the crystal. Unlike conventional flat-edge crystals, the beveled profile allows the sapphire to sit slightly above the insert, giving your watch a more premium and sophisticated appearance. This subtle detail adds depth and enhances the overall proportions of the build.
Our double dome sapphire crystals are compatible with:
Whether you're building a classic diver or a modern GMT, these crystals offer excellent scratch resistance and a clean, distortion-free view of your dial while adding a premium finishing touch to your custom watch.
Blue AR Double Dome Sapphire Crystal
The Blue AR is designed for modders who want their crystal to become a defining feature of the watch. With an overall height of 5.1mm, it creates a bold, vintage-inspired profile that stands proudly above the bezel.
For the best visual effect, we recommend pairing the Blue AR with a standard-height rotating bezel and a flat bezel insert. This combination maximizes the visible dome, creating a striking layered appearance that highlights the craftsmanship of your build.
If paired with a sloping insert, the crystal will sit lower relative to the bezel, reducing the apparent height while still maintaining the elegant double dome aesthetic.
Featuring a smooth beveled edge and clear underside anti-reflective coating, the Blue AR offers exceptional clarity and a premium look for SKX007, SKX009, SRPD 5KX, and Seiko 5 GMT SSK builds.
The Clear AR Double Dome Sapphire Crystal is designed for builders who prefer a clean, modern profile without sacrificing the classic look of a domed crystal. With an overall height of 4.7mm, it offers a lower profile than the Blue AR, making it the ideal choice for streamlined custom builds.
This crystal is highly recommended for use with our Slim Rotating Bezel and Flat Bezel Inserts, creating a balanced, factory-like appearance with a smooth transition between the insert and crystal. Its carefully machined beveled edgeallows the sapphire to sit elegantly above the insert, adding depth and a premium finishing touch.
Constructed from scratch-resistant sapphire and featuring a clear anti-reflective coating on the underside, the Clear AR improves dial clarity while maintaining the true colors of your watch. The protected AR coating also ensures long-lasting performance without the risk of surface wear.
Whether you're building a minimalist diver or a modern GMT, the Clear AR delivers the perfect combination of durability, clarity, and refined aesthetics.
