About this watch

The Omega Speedmaster Professional Galaxy Express, a limited edition timepiece that has captured the hearts of collectors and enthusiasts alike. This stunning watch is part of the iconic Speedmaster Moonwatch family, produced in 1999 with only 1,999 units made. It's a piece of history that tells a story of horological excellence and space exploration. Crafted from stainless steel, this watch combines durability with a luxurious feel. The round case, measuring 42.00 mm in diameter, is a perfect size for both men and women, and the 20.00 mm lug width provides a comfortable fit on the wrist. The tachymeter bezel is not just a design choice; it's a functional element that allows the wearer to calculate speed over distance. The plexiglass glass adds a vintage charm and is less prone to shattering, making it practical for everyday wear. This watch features an open case back, allowing you to admire the exquisite Omega caliber 1861 movement within. With a water resistance of 50 meters, while it's not a diver's watch, it can withstand splashes and brief immersion in water—perfect for daily wear without constant worry. The black dial is classic and timeless, adorned with stick and dot indexes that enhance readability. The hands are also stick-shaped, offering a sleek look that complements the overall design. It's a watch that strikes a balance between elegance and functionality. Being one of only 1,999 units produced, the Galaxy Express carries a unique charm. Limited editions often have a special allure, and this watch is no exception. Thanks to the Omega caliber 1861 movement, the Galaxy Express offers exceptional accuracy. Whether you're timing a meeting or enjoying a leisurely stroll, you can trust this watch to keep precise time. Plus, the hand-wound feature adds a personal touch; winding it yourself is almost a ritual. With its stainless steel build and durable plexiglass, the Galaxy Express is designed to withstand the rigors of everyday life. Whether you're at work or out on the town, it feels great to wear. This watch is incredibly versatile. It can easily transition from casual to formal settings. Pair it with jeans and a t-shirt for a laid-back vibe or with a suit for a more polished look. It's that kind of watch that goes with almost anything in your wardrobe.
