Omega Seamaster Railmaster Omega Co-Axial Master Chronometer Watch - 40 mm Steel Case - Vertically Brushed Grey Dial - 220.10.40.20.06.001

Forty millimeters of brushed stainless steel creates an understated presence on the wrist, where the vertically brushed grey dial catches light with industrial precision. The Omega Seamaster Railmaster in reference 220.10.40.20.06.001 delivers the anti-magnetic heritage of its 1957 ancestor through thoroughly modern Co-Axial Master Chronometer movement architecture. This unworn example maintains the collection's original purpose-built ethos—created for scientists and engineers working near powerful magnetic fields—while incorporating Omega's most advanced timekeeping technology. The 40mm case diameter strikes the ideal balance between vintage proportions and contemporary wrist presence.
