Since its debut in 1957, Omega’s iconic Speedmaster chronograph, nicknamed “Moonwatch” for its presence on all six NASA lunar missions, sported a tricompax dial arrangement. In 2011, Omega outfitted the watch with a new co-axial movement and bicompax design, both of which are used again in the first Moonwatch with a black ceramic case, unveiled at Baselworld 2013.

The Omega Speedmaster Moonwatch “Dark Side of the Moon” derives its name from its black zirconium oxide ceramic dial and matching black ceramic case, which is 44.25 mm in diameter and boasts both brushed and polished finishes. The dial is notable for its applied indices, made of 18k white gold, and the two blackened subdials at 3 o’clock and 6 o’clock. This new bicompax subdial arrangement was first used on the Omega Speedmaster Moonwatch Co-Axial Chronograph, the first Moonwatch to contain Omega’s in-house chronograph Caliber 9300. As on that model, the subdial at 3 o’clock serves as both the 12-hour and 60-minute counter, using two hands to display the elapsed time intuitively. The small seconds subdial is at 9 o’clock, and the date is displayed on a window at 6 o’clock, the spot occupied by the elapsed-hours subdial in older models.
