Omega - Speedmaster Professional Moonwatch – Green – 3106042501001 – 2026

The Omega Speedmaster Professional Moonwatch carries the same manually-wound chronograph architecture Omega originally qualified for NASA spaceflight in the 1960s, and remains the reference point for the brand's chronograph line today. This example is cased in yellow gold with a green dial, a precious-metal presentation that keeps the Moonwatch's tachymeter bezel, three-register chronograph layout, and stepped lugs while dressing the design up from the standard steel execution.

Inside is Omega's manually-wound Moonwatch calibre, built around the manufacture's column-wheel chronograph architecture and finished to Omega's Co-Axial Master Chronometer standard on current-production examples of this line. The movement is hand-wound rather than automatic, a deliberate continuation of the original Moonwatch's mechanism, and the case carries the domed hesalite or sapphire crystal and screw-down caseback typical of this reference family.
