Originally introduced in 1957 for engineers, scientists, and railway professionals working around strong magnetic fields, the Omega Railmaster has become one of the brand's most understated and capable tool watches. The modern 220.10.40.20.06.001 remains true to that heritage, pairing a 40mm stainless steel case with a distinctive vertically brushed grey dial and Omega's industry-leading anti-magnetic technology. Clean, highly legible, and effortlessly versatile, it is a watch equally suited to everyday wear and weekend adventures.
Powering the watch is the Omega Co-Axial Master Chronometer Calibre 8806, a METAS-certified automatic movement offering exceptional precision, reliability, and resistance to magnetic fields of up to 15,000 gauss. Featuring Omega's Co-Axial escapement, silicon balance spring, and approximately 55 hours of power reserve, it represents the pinnacle of modern mechanical watchmaking.
