Seamaster Railmaster Co-Axial Master Chronometer 40mm
SeamasterRailmaster40 mm, steel on steel
The 40mm symmetrical case is made from stainless steel with a wave-edged design featured on the back. The vertically brushed black dial includes brushed
stainless steel hands and recessed hour-markers which are all filled with “vintage” Super-LumiNova. There is also a transferred beige “Railmaster” indication
which delivers a classic touch.
The watch has a fully brushed and integrated stainless steel bracelet and the oriented caseback features a NAIAD LOCK design (patent pending) to keep the
wording upright. The watch is driven by the OMEGA Co-Axial Master Chronometer Calibre 8806. Certified at the industry’s highest standard by the Swiss
Federal Institute of Metrology (METAS) and able to withstand magnetism of 15,000 gauss, this Railmaster model recalls the superb anti-magnetic qualities
of its predecessor.
