• Unexpected and Coveted White Lacquered Dial: Inspired by NASA’s space prototypes (Alaska I) and astronauts’ suits, featuring a stepped finish, logo, and raised hour markers.
• Double Sapphire Crystal (Sapphire Sandwich): Anti-reflective domed sapphire crystal on the dial and a transparent case back that reveals the movement’s architecture.
• Co-Axial Master Chronometer Caliber 3861: METAS-certified hand-wound movement, with resistance to magnetic fields of up to 15,000 gauss and a 50-hour power reserve.
• 4th-Generation Design (ST 105.012): 42-mm asymmetrical case with crown guard, bracelet featuring 5 links per row (polished and brushed), and “Dot Over Ninety” (DON) bezel.
• Optimized Bracelet with Micro-Adjustment: Ergonomic stainless steel construction that flows smoothly toward the wrist, featuring a folding clasp with a comfortable adjustment mechanism (comfort release).

Product Description

The Omega Speedmaster Moonwatch Professional “White Dial” (Ref. 310.30.42.50.04.001) reinterprets the most legendary chronograph in the history of watchmaking with a spectacular pure white lacquered dial. This shade not only evokes the EVA suits worn by astronauts during their spacewalks but also pays tribute to the iconic Project Alaska I of 1969.

Built around the iconic 42-mm asymmetrical case in stainless steel, it retains the hallmarks of the fourth-generation Moonwatches that landed on the Moon: a stepped dial architecture (step dial), high-contrast black-oxidized hands with luminescent material, and the anodized aluminum bezel featuring the famous “Dot Over Ninety” (DON) marking. Unlike the Hesalite versions, the Sapphire Sandwich configuration features scratch-resistant sapphire crystal on both sides, revealing the internal mechanics through the case back.

At its heart beats the OMEGA Caliber 3861, a hand-wound movement—the modern evolution equipped with a Co-Axial escapement and a silicon balance spring. Certified as a Master Chronometer, this timepiece guarantees unwavering chronometric precision in the face of extreme temperature fluctuations and powerful magnetic fields.
