The OMEGA Seamaster Railmaster 38 mm reference 235.10.38.20.13.001 is a heritage-inspired timepiece that blends vintage charm with modern watchmaking innovation. Originally launched in 1957 as part of OMEGA’s “Professional Trilogy,” the Railmaster was designed for those working near strong magnetic fields, such as railway workers and scientists. This contemporary 38 mm stainless steel model features a vertically brushed brown dial with a subtle vintage tone, complemented by recessed hour markers filled with beige Super-LumiNova for a warm, retro aesthetic. Its symmetrical case, brushed surfaces, and domed sapphire crystal with anti-reflective treatment on both sides enhance its timeless appeal, making it a versatile everyday luxury watch.
At the heart of the OMEGA Seamaster Railmaster 38 mm beats the Co-Axial Master Chronometer Calibre 8806, a movement certified by METAS to withstand magnetic fields up to 15,000 gauss while delivering exceptional precision and reliability. The calibre offers a 55-hour power reserve, a free-sprung balance with silicon balance spring, and Geneva waves in arabesque, visible through the transparent caseback. This robust engineering ensures the Railmaster is as technically advanced as it is stylish, embodying OMEGA’s dedication to producing timepieces that combine durability, performance, and elegance.
The Railmaster 235.10.38.20.13.001 is fitted with a stainless steel bracelet featuring a mix of polished and brushed finishes for both comfort and refined style. Its clean, no-date dial layout emphasizes legibility, while the crosshair detail at the center reinforces its precision-focused heritage. Water resistant to 150 meters, this watch is ready for both urban and outdoor adventures, making it ideal for those who appreciate understated luxury with a strong historical legacy. With its combination of vintage-inspired design, anti-magnetic mastery, and versatile wearability, the OMEGA Seamaster Railmaster remains a standout choice for collectors and enthusiasts seeking a watch that merges history with cutting-edge technology.
