Omega Speedmaster Speedmaster Professional Plexi / Bracelet
Reference 3570.50.00
About this watch
The Omega Speedmaster Professional Plexi is a masterpiece of horology, a testament to precision and a symbol of human achievement. Its rich history, from being the first watch worn on the moon to its durable stainless steel construction, makes it a collector's item and a statement of style. The classic design, with its timeless aesthetics, is suitable for any occasion, while the reliable Omega caliber 1861 movement delivers excellent precision. The chronograph functionality allows for precise timing, and although the Plexiglass may be prone to scratches, it adds a vintage charm to this luxury watch. With a water resistance of 50 meters, it's practical but not designed for diving. Manual winding requires regular maintenance, but the Speedmaster Professional Plexi is worth it.
