Omega Speedmaster Moonwatch Calibre 321 — Platinum Onyx Dial

The Omega Speedmaster Moonwatch Calibre 321 in platinum represents the pinnacle of craftsmanship and heritage within the Speedmaster collection. Combining noble materials with Omega’s legendary chronograph movement, this watch honors the original Moonwatch design while elevating it to new levels of refinement.

It features a 42 mm platinum case with a transparent back that reveals the meticulously recreated Calibre Omega 321 — the same manual-winding movement that powered the watches worn during NASA’s Apollo missions. The black ceramic bezel frames a striking black onyx dial, offering a deep, mirror-like finish. Protected by a scratch-resistant sapphire crystal with anti-reflective treatment on both sides, this masterpiece provides approximately 55 hours of power reserve and is fitted with a sleek black leather strap. Water resistant to 50 metres (167 feet), it perfectly balances timeless elegance with historic engineering.
