About this watch

The Omega Speedmaster Professional Moonwatch 3861 Sedna Gold is a legendary timepiece that combines heritage, craftsmanship, and functionality in a way that few can match. Its stunning aesthetics, featuring a unique blend of black and gold, create a luxurious yet sporty vibe that can transition seamlessly from casual to formal settings. The watch strikes a balance between boldness and wearability, with a 42mm diameter and 13.18mm height that ensures it will never go out of style. Inside this beauty lies the Omega caliber 3861, an updated version of earlier calibers featuring a co-axial escapement and silicon balance spring. Certified by METAS, this watch is not just accurate but highly resistant to magnetic fields reaching up to 15,000 gauss. With a manual-winding chronograph movement and power reserve of 50 hours, you'll have the pleasure of winding it yourself while enjoying precise timekeeping. The black sunburst finish dial is mesmerizing, providing a backdrop for stick hands that lend a sleek, modern look while ensuring legibility at a glance. One of the standout features of the Speedmaster is its durability, with scratch-resistant sapphire glass and a water resistance rating of 50 meters. The open case back allows you to admire the intricate workings of the Omega caliber 3861, making it a treat for watch lovers.
