Reference 220.10.40.20.01.001 presents the Railmaster in its most purposeful form. The round 40mm stainless steel case is fitted with a scratch-resistant sapphire crystal, a fixed bezel, a screw-in crown, and a solid case back, while water resistance extends to 150 metres / 500 feet.
Inside beats an automatic Co-Axial Master Chronometer movement that holds COSC certification, reflecting a high standard of precision and regulation. The black dial sits behind the sapphire crystal, offering clear legibility in a clean, no-frills presentation.
A brushed stainless steel bracelet with 20mm lug width completes the watch, secured by a push-button deployant buckle with push-button quick micro adjustment for a dialled-in fit on the wrist.
