About this watch

The Omega Speedmaster Professional Moonwatch 3861 is a masterpiece that combines timeless elegance with modern technology. Founded in 1848, Omega has been a pillar in the world of horology, synonymous with precision and innovation. From its stunning design to its robust functionality, it encapsulates the spirit of adventure and precision that Omega is known for. The Speedmaster line has always been a favorite, and the 3861 model is no exception. With a diameter of 42 mm, the stainless steel case provides both durability and a polished aesthetic. The tachymeter bezel allows for speed calculations over a known distance, making it not just a pretty face but a functional tool. At the heart of the Speedmaster Professional Moonwatch is the Omega Caliber 3861, a hand-wound movement that's a modern upgrade from previous models, incorporating a co-axial escapement and a silicon balance spring. The craftsmanship is evident in the intricate details of the movement, which you can admire through the closed case back.
