Omega Speedmaster Moonwatch Professional White 3861 Sapphire 310.30.42.50.04.001

Overview 

The Omega Alaska Project — a series of experimental Speedmaster prototypes developed for NASA in the 1970s — featured white cases and dials to reflect solar radiation and manage thermal extremes in space. The 310.30.42.50.04.001 is the Moonwatch Professional's acknowledgment of that development chapter: white dial, black contrast elements, sapphire crystal, and the Calibre 3861 architecture in the configuration that makes the Alaska Project aesthetic available in mainstream production. It is the Speedmaster that asks a question most Moonwatch configurations don't raise.

The case is 42mm 316L stainless steel with twisted lugs — the Speedmaster's characteristic case architecture unchanged since the 1960s. The white dial reverses the Moonwatch's standard contrast logic: black printed hour markers and black hands read against white rather than the expected black, with the black anodized aluminum tachymeter bezel reinforcing that reversal at the perimeter. Sapphire crystal replaces the acrylic Hesalite of the standard professional references — trading the historically accurate specification for movement visibility through both the front crystal and the sapphire caseback. Stainless steel bracelet with polished and brushed finishing.

The Calibre 3861 is Omega's hand-wound Co-Axial Master Chronometer — the modern upgrade to the movement architecture that powered the original Moonwatches. METAS Master Chronometer certification covers magnetic resistance to 15,000 gauss and independently verified accuracy between 0 and +5 seconds per day on the wrist. The silicon balance spring and Co-Axial escapement replace the 1861's older lever and hairspring; power reserve is 50 hours, with the movement visible through the sapphire caseback.

Within the current 3861 Moonwatch lineup, the white dial sapphire reference occupies a distinct position from the Hesalite: sapphire crystal enables movement visibility the Hesalite's solid caseback doesn't permit, and the white dial produces a fundamentally different reading of the Speedmaster's visual language. The Hesalite holds the historically accurate specification with a secondary market collector following; the white dial 04.001 carries its value on visual distinction and Alaska Project provenance, drawing a different buyer. We see the white dial at RM33,800 against an RRP of RM39,750 as a well-priced entry into the most visually distinctive current-production Moonwatch — below retail, brand new, complete set. Brand new, unworn, complete with box and papers dated May 2026, at RM33,800.
