About this watch
The Omega Seamaster Aqua Terra 150M Hand Wound 49.2 Railmaster is a masterpiece that embodies elegance, precision, and rich history. With its stunning black dial adorned with mixed indexes and arrow hands, this timepiece commands attention on the wrist. The small seconds sub-dial adds a touch of sophistication, making it not just a tool for timekeeping but also a piece of art. At the core of the Seamaster Aqua Terra is the Omega caliber 2201, a hand-wound movement based on the legendary Unitas 6498. This movement is a testament to Omega's engineering prowess, with 17 jewels, a power reserve of 53 hours, and a frequency of 21,600 vibrations per hour. Complementing the luxurious white gold case is a sumptuous brown alligator strap that provides a comfortable fit for extended wear. The watch feels surprisingly light on the wrist, thanks to Omega's expertise in balancing materials. With its unique blend of sportiness and elegance, this limited edition model stands out from other Omega watches, such as the Speedmaster or Seamaster Professional. Owning a limited edition Omega is like holding a piece of horological history, making it a coveted piece for collectors.
