Omega Speedmaster Professional Moonwatch - 310.30.42.50.04.001 - 42 mm - Stainless Steel

The Omega Speedmaster Moonwatch Professional ref. 310.30.42.50.04.001 is part of the Speedmaster collection and retains the classic lines that have defined the Moonwatch Professional model, in a version that immediately stands out through the contrast between the white dial and the black details.

The 42 mm case is made of stainless steel, featuring the asymmetrical design specific to this line, and is complemented by a black anodized aluminum bezel with a tachymeter scale. The official dimensions—42 mm in diameter, 13.18 mm in thickness, and 47.50 mm lug-to-lug—preserve the well-known proportions of this model.

The watch is equipped with the Omega Caliber 3861, a manual-winding chronograph movement with Co-Axial escapement and Master Chronometer certification. It offers a power reserve of 50 hours and resistance to magnetic fields of up to 15,000 gauss, while maintaining the classic architecture associated with a Speedmaster Moonwatch Professional.

The watch features a scratch-resistant sapphire crystal with anti-reflective treatment, and the beauty of the movement can be admired through the open caseback, where the same type of sapphire crystal is also used on the back of the watch. Water resistance is rated at 50 meters, and the stainless steel bracelet perfectly complements the classic character of this Speedmaster.
