Omega Speedmaster Speedmaster Professional Moonwatch Alaska Project II

Reference ST 145.0022 Alaska II

About this watch

The Omega ST 145.0022 Alaska III Speedmaster Professional Moonwatch is a masterpiece that combines functionality, style, and a rich heritage. This limited edition timepiece is part of the legendary Speedmaster family, which has been synonymous with space exploration since the 1960s. Produced in 1978 as part of the Alaska Project—a NASA initiative to develop a watch that could withstand extreme conditions—only 56 units were made. With its striking aesthetics and storied past, the Alaska III is more than just a watch; it's a conversation starter, a collectible, and a piece of art that you can wear on your wrist. The Omega caliber 861 movement powers this beauty, providing a power reserve of about 48 hours and featuring 18 jewels. The chronograph function allows you to measure elapsed time, making it perfect for sports lovers and adventurers. With a water resistance of 50 meters and a stainless steel case designed to resist scratches and dents, the Alaska III is built to withstand the rigors of space travel. But even if you're not a collector, this watch is perfect for anyone who appreciates craftsmanship, history, and style. It's great for both casual outings and formal events, making it a versatile addition to any wardrobe.
