The Omega Speedmaster Professional Moonwatch Yellow Gold Green Dial 42mm Ref. 310.63.42.50.10.001 brings a bold, modern twist to an iconic design. Crafted in 18K Moonshine Gold, the 42mm case honors the legendary 4th-generation Speedmaster with its asymmetrical design and historical details. A sun-brushed green PVD step dial pairs beautifully with the green ceramic bezel, which features a Ceragold tachymeter scale and the famous "dot over 90." Powered by the Co-Axial Master Chronometer Calibre 3861, this manual-winding movement ensures exceptional precision, magnetic resistance, and a 50-hour power reserve. The chronograph functionality includes small seconds, 30-minute, and 12-hour counters, along with a central chronograph hand. Paired with a green alligator leather strap and an 18K Moonshine Gold pin buckle, the watch is secured comfortably on the wrist. With a polished gold caseback engraved with "FIRST WATCH WORN ON THE MOON," this timepiece is a luxurious nod to Omega’s pioneering legacy.
