Custom Sapphire Tourbillon Watch – OEM Watch Manufacturer

Deep-Sea Inspiration and Skeleton Architecture

Drawing inspiration from the quiet depths of the oceanic abyss, we engineered this manual-wind tourbillon timepiece with a focus on open-work transparency. Specifically, a blue outer ring framing a sandblasted black inner dial creates a strong visual contrast while absorbing stray light reflections. Simultaneously, bevel-cut skeleton apertures around the 9 o’clock position reveal smooth, hand-finished bridge edges. Consequently, the overall layout presents a clean, functional architectural balance on the wrist.

Where conventional watches conceal their movement structure beneath opaque metal plates, we integrated a transparent sapphire mainplate to expose the gear train. Therefore, the manual-wind tourbillon regulation organ sits completely exposed at 9 o’clock, rotating continuously within a smooth precision aperture. In fact, for optimal low-light legibility, we coated the faceted hands and indices with Swiss Super-LumiNova ice-blue luminous material. As a result, the dial delivers high contrast and instant time-reading across any lighting environment.

Meanwhile, driving this open-heart display is a slim 5.37 mm manual-wind tourbillon movement operating at 28,800 vibrations per hour (4Hz). Additionally, equipped with 20 synthetic ruby jewels and an extended 65-hour power reserve, the caliber provides exceptional rate stability over long wear cycles. Simultaneously, we housed the assembly within a polished stainless steel case paired with an integrated blue alligator-grained leather strap. Turn the watch over, and the full sapphire construction showcases the mechanical gear movement from both sides.Ultimately, as a specialized watch manufacturing facility, we offer full-scope OEM and ODM

customization options, including custom logo execution, modified dial colorways, or specialized strap pairing for your brand.
