Reference ST 145.0022 Alaska III
About this watch
The Omega ST 145.0022 Alaska III Speedmaster Professional Moonwatch is a masterpiece that combines functionality, style, and rich heritage. This limited-edition timepiece is steeped in history and craftsmanship, born out of the Alaska Project—a NASA initiative to develop a watch that could withstand extreme conditions. With only 56 units made, it's as much a collector's item as it is a functional timepiece. The matte black finish is both sleek and understated, allowing it to blend in with casual and formal outfits alike. The round case is classic and timeless, measuring a comfortable 42mm in diameter, making it suitable for various wrist sizes. The tachymeter bezel is a nod to its sporty nature, while the plexiglass adds a vintage touch that many enthusiasts adore. The dial of the Alaska III is where things get interesting, with stick and dot indexes giving it a clean, streamlined look. This watch is perfect for those who appreciate a classic design without the frills. The Omega caliber 861 movement is not just reliable; it's a piece of history, used in the second generation of 'moon watches.' It features 18 jewels, providing a power reserve of about 48 hours and a chronograph function that allows you to measure elapsed time—a handy feature for sports lovers and adventurers. Built to withstand the rigors of space travel, the Omega Alaska III is no slouch when it comes to durability, with a water resistance of 50 meters. The stainless steel case adds to the watch's aesthetic appeal and contributes to its robustness. Owning one is like possessing a fragment of that exciting era. It's great for both casual outings and formal events, making it a versatile addition to any wardrobe.
