About this watch
The Omega Seamaster Aqua Terra Railmaster reference 220.12.40.20.01.001 is a modern reinterpretation of a historic anti-magnetic timepiece, combining vintage inspiration with advanced technology. This certified pre-owned luxury watch features a 40 mm stainless steel case paired with a durable fabric strap, offering both comfort and a distinctive tool-watch aesthetic.
The black dial is clean and highly legible, featuring recessed hour markers and broad arrow hands filled with Super-LumiNova, ensuring excellent readability in all conditions. The minimalist layout, without a date display, reinforces the watch’s utilitarian design and pays tribute to the original Railmaster models. The subtle gradient effect on the dial adds depth and character.
Powered by the automatic Omega Co-Axial Master Chronometer calibre 8806, this in-house movement is METAS-certified, delivering exceptional precision, anti-magnetic resistance up to 15,000 gauss, and outstanding reliability. It offers a power reserve of approximately 55 hours, making it ideal for daily wear.
The fabric strap enhances comfort and reinforces the watch’s vintage-inspired character while remaining highly practical. Offered in very good condition and presented as a full set with its original box and papers, this model is a highly desirable pre-owned luxury watch.
The Seamaster Railmaster stands out for its minimalist design, advanced anti-magnetic technology, and strong historical roots.
