The Omega Speedmaster Professional Moonwatch Rose Gold Diamond Brown Dial 42mm Ref. 310.55.42.50.13.001 is a luxurious evolution of the iconic Moonwatch. Crafted in 18K Sedna Gold, Omega’s unique rose gold alloy, the 42mm asymmetrical case is inspired by the 4th-generation Speedmaster. Its diamond-paved bezel adds a refined touch, perfectly complementing the sun-brushed brown step dial with applied indexes. Powered by the Co-Axial Master Chronometer Calibre 3861, this manual-winding movement delivers exceptional precision, magnetic resistance, and a 50-hour power reserve. The chronograph function includes small seconds, a 30-minute counter, and a 12-hour counter, along with a central chronograph hand. Paired with a five-arched-links-per-row bracelet in 18K Sedna Gold and secured with a matching deployment clasp, this piece offers both comfort and durability. Protected by sapphire crystal and water-resistant to 50 meters, this Moonwatch blends Omega’s space heritage with contemporary luxury, making it a standout statement in horology.
