About this watch

The Omega Seamaster Diver 300M 522.92.44.20.04.001 debuted in 2026 as a special edition linked to the Olympic Winter Games Milano Cortina 2026. The watch is housed in a 43.5 mm case combining white ceramic and grade 5 titanium, with a total thickness of 14.37 mm and a lug-to-lug measurement of 51.5 mm. Water resistance is rated to 300 meters (30 bar). The case is fitted with a domed sapphire crystal with anti-reflective treatment on both sides. The unidirectional bezel is manufactured from white ceramic and features a laser-engraved diving scale executed in positive relief. The dial is made of white ceramic with a matte, laser-treated surface and incorporates a textured pattern derived from the “26” of the Milano Cortina 2026 emblem. Rhodium-plated hands and applied indices are filled with white Super-LumiNova. The central seconds hand is finished with a blue gradient lacquer. The display is limited to hours, minutes, and seconds, with no date indication. The case back is crafted from grade 5 titanium and is embossed with the Milano Cortina 2026 emblem. Inside, the watch is powered by the Omega Co-Axial Master Chronometer Calibre 8806. This automatic movement provides a power reserve of approximately 55 hours and meets Master Chronometer certification standards. The watch is delivered on a white rubber strap secured by a pin buckle in grade 5 titanium. The lug width measures 21 mm, and the total weight of the watch is approximately 109 grams.
