The reference 310.30.42.50.01.004 is the current-generation stainless steel Moonwatch in the sapphire crystal configuration. It features the traditional black stepped dial with white printed chronograph registers, white baton hands and applied Omega logo, paired with a sapphire crystal front and sapphire display caseback.
This model is powered by the manually wound calibre 3861, a Co-Axial Master Chronometer movement certified by METAS. It provides approximately 50 hours power reserve and is resistant to magnetic fields up to 15,000 gauss. The movement is visible through the sapphire caseback.
The black anodised aluminium tachymeter bezel retains the “Dot Over Ninety” detail consistent with classic Speedmaster design language.
This February 2026 example is unworn and supplied as a complete full set.
