Omega Speedmaster Dark Side of the Moon Co-Axial Chronometer Chronograph 44.25mm Ceramic White Mother Of Pearl Diamond Dial & Bezel Leather Strap 311.98.44.51.55.001 - BRAND NEW

The Omega Speedmaster has defined precision timekeeping since 1957, earning its place in horological history as the watch chosen by NASA for its Apollo missions. Within that legendary lineage, the Dark Side of the Moon collection represents Omega's most daring material innovation — constructing the entire 44.25mm case from high-tech black ceramic, a material celebrated for its extreme scratch resistance, featherlight feel on the wrist, and deep, non-reflective luster that no conventional metal can replicate.

Reference 311.98.44.51.55.001 elevates the Dark Side of the Moon concept into the realm of haute joaillerie. The white mother-of-pearl dial provides a softly iridescent, organically beautiful canvas that shifts with the light, offering a striking contrast against the obsidian-black ceramic case. Diamond indices complete the dial, adding brilliance and a sense of quiet opulence that distinguishes this variant from every other Speedmaster in the catalog.

The bezel of this reference is set with diamonds, transforming the iconic Speedmaster silhouette — long associated with astronauts and professional timing — into a jeweled statement piece. The craftsmanship required to set stones precisely into a ceramic bezel is considerable; ceramic cannot be re-worked like precious metal, demanding that every diamond be placed with absolute accuracy the first time. The result is a bezel that combines the toughness of ceramic with the sparkle of fine jewelry.

At the heart of this watch beats Omega's Co-Axial Chronometer-certified chronograph movement. The Co-Axial escapement, a technology Omega pioneered for commercial watchmaking, reduces friction in the gear train and contributes to long-term accuracy and reduced need for servicing compared with traditional Swiss lever escapements. Chronometer certification from COSC means this movement has passed rigorous independent timing tests, confirming its precision credentials worthy of both the Speedmaster name and the gem-set exterior.

Worn on a supple leather strap, the 44.25mm ceramic case presents with commanding wrist presence without the cold weight of a metal bracelet, making it comfortable for extended wear. The juxtaposition of the black case with the white mother-of-pearl and diamond-set bezel creates a day-to-night versatility rarely achieved in a watch of this size.
