The OMEGA Speedmaster Moonwatch White Dial 42mm (Ref. 310.30.42.50.04.001) draws inspiration from the 4th generation Speedmaster worn on the moon through authentic asymmetrical case design and white lacquered step dial with applied OMEGA logo and indexes. Part of all six moon landings, this legendary chronograph carries the famous dot over 90 on the black anodised aluminium bezel ring alongside Moonwatch style hands as faithful references to the watches that defined OMEGA’s space exploration legacy.

At 42mm with 13.18mm thickness through polished-brushed stainless steel construction, this provides authentic Moonwatch proportions whilst sapphire crystal glass on both front and caseback enables movement appreciation whilst maintaining contemporary durability. The white lacquered step dial creates clean, legible presentation distinct from the classic black dial whilst retaining all period-correct design references.

The Co-Axial Master Chronometer Calibre 3861 delivers 50-hour power reserve with 15,000 gauss magnetic resistance through METAS certification whilst the manual-winding chronograph with Co-Axial escapement ensures precision timing. The free-sprung balance with silicon balance spring and rhodium-plated finish with straight Geneva waves complete an exceptional movement specification.

The scratch-resistant sapphire crystal with anti-reflective inner treatment ensures optimal clarity whilst the polished-brushed bracelet with foldover clasp and comfort setting provides secure daily wear. The 50m water resistance covers practical requirements. The white dial Moonwatch occupies a distinct position within the range, offering the full Master Chronometer 3861 specification and 4th generation design references in a configuration that wears considerably lighter visually than the standard black.
