Omega Speedmaster Speedmaster Professional Missions Skylab 3

Reference 3597.23.00

About this watch

The Omega Speedmaster Professional Missions Skylab 3 is a true gem from the Speedmaster family, boasting a rich heritage and unique charm. This limited edition watch is not just a timepiece; it's a piece of history, with only 200 units produced between 1997 and 1998. The black dial, paired with stainless steel, radiates sophistication and demands attention without being overly flashy. The 42.00 mm round case strikes a perfect balance between boldness and wearability, while the stick and dot indexes provide a clean, minimalist look that is both practical and stylish. At the core of this masterpiece is the Omega caliber 1861 movement, a hand-wound chronograph movement boasting a 48-hour power reserve and a frequency of 21,600 vibrations per hour. The watch features 18 jewels in its movement, enhancing its reliability and accuracy, and has a water resistance of up to 50 meters, making it versatile enough for everyday wear. With its limited production and connection to space missions, the Skylab 3 offers a sense of exclusivity that watch enthusiasts can genuinely appreciate.
