Omega Speedmaster Speedmaster Professional Moonwatch

Reference 3870.50.31

About this watch

The Omega Speedmaster Professional Moonwatch (model 3870.50.31) is a masterpiece of watchmaking. This iconic timepiece has been to the moon and back, thanks to its association with the Apollo 11 mission in 1969. At its heart lies the Omega caliber 1861, a hand-wound movement that's both reliable and precise. With a frequency of 21,600 vibrations per hour and a power reserve of 48 hours, this watch is designed to keep you on time for your next adventure. The black dial is elegantly accented by stick and dot indexes, making it both readable and stylish. Its stainless steel case with a round shape and diameter of 42.00 mm exudes sophistication, while the tachymetric bezel adds a sporty edge. Whether you're in a boardroom or at a casual gathering, this watch makes a statement. The Speedmaster's versatility is unmatched, effortlessly transitioning from a dress watch to a casual piece. Pair it with a crisp suit or a relaxed T-shirt, and it fits right in. Its durability and accuracy have made it the perfect companion for astronauts, and its rich heritage is a testament to Omega's engineering prowess.
