Unworn, Omega Seamaster Diver 300M, Ref# 522.92.44.20.04.002, box and papers.

The OMEGA Seamaster Diver 300M "Milano Cortina 2026" Ref. 522.92.44.20.04.002 is a striking Special Edition created to celebrate OMEGA's role as Official Timekeeper of the Olympic Winter Games Milano Cortina 2026. Combining innovative materials with the legendary Seamaster Diver 300M design, this exceptional timepiece features a lightweight 43.5 mm case crafted from white ceramic and Grade 5 titanium. The polished white ceramic dial delivers a clean, contemporary appearance, enhanced by laser-engraved wave motifs, applied indexes filled with white Super-LumiNova, and skeletonized hands that ensure exceptional legibility. A unidirectional white ceramic bezel with a diving scale in positive relief reinforces the watch's professional diving credentials, while the domed sapphire crystal with anti-reflective treatment on both sides provides outstanding clarity and durability. At its heart beats the OMEGA Co-Axial Master Chronometer Calibre 8806, a METAS-certified self-winding movement offering resistance to magnetic fields up to 15,000 gauss, a Co-Axial escapement, free-sprung balance with silicon balance spring, and a 55-hour power reserve. The commemorative Milano Cortina 2026 medallion engraved on the titanium caseback highlights the watch's Olympic heritage. Completing the design is a comfortable white integrated rubber strap secured by a titanium pin buckle, creating a bold yet lightweight sports watch equally suited for everyday wear and adventure. Water-resistant to 300 meters.
