Pre-owned Omega Speedmaster Moonwatch Professional ref 310.60.42.50.10.001 is a striking yellow gold Moon Watch, affectionately referred to by the brand as “Moonshine Gold.” While gold might seem an unnatural option afforded to the notoriously rugged lunar-exploring Speedy, this model is far from the first in precious metal. There have been numerous yellow gold models throughout the collection’s history, and more recently, a more conspicuous Canopus white gold model and a Sedna rose gold model. Released in early 2022, ref. 310.60.42.50.10.001 is the yellow-gold model with a striking green step dial decorated with classic Moon Watch-style hands. Inspired by the 4th generation Speedmaster, the green ceramic bezel is adorned with a Ceragold tachymeter scale and the Dot-Over-90 marker. Lastly, the watch is powered by the caliber 3861, a Master Chronometer with a special finish. Shop OMEGA Speedmaster Collection
