Housed in a 40mm round stainless steel case, this Railmaster is built around Omega's Co-Axial Master Chronometer automatic movement, COSC certified for precision. A fixed bezel, screw-in crown, solid case back, and 150m/500ft of water resistance give the watch a robust, purposeful character.
The blue dial sits behind a scratch-resistant sapphire crystal, while the solid case back keeps the movement protected. A 20mm lug width accommodates the blue fabric strap, lending the piece a relaxed yet refined wrist presence that sets it apart from more conventional metal bracelet configurations.
Reference 220.12.40.20.03.001 is offered in new/unworn condition, representing the Railmaster line's enduring commitment to combining antimagnetic heritage with contemporary standards of accuracy.
