This Omega Seamaster Railmaster Co-Axial Master Chronometer is an automatic wristwatch dating from the 2020s. The timepiece is housed in a 40mm stainless steel case featuring twisted lugs, a brushed bezel, and a signed crown.

The brushed gray dial is equipped with printed Arabic numerals at the cardinal positions, luminous triangular hour markers, a matching handset, and an outer railroad minute track. The watch is powered by the automatic Omega Co-Axial Master Chronometer Calibre 8806, which is rated to resist magnetic fields of up to 15,000 Gauss and offers a power reserve of 55 hours. The watch is fitted with a stainless steel bracelet that incorporates a signed hidden deployant clasp.

The source reports the condition of the watch as being in as-new condition, noting it as a contemporary interpretation of an Omega design originally introduced in 1957.

Design

Visible features
• The dial features a brushed finish with luminous triangular indices. • The case includes signature twisted lugs and a brushed bezel. • The bracelet is constructed with a hidden deployant clasp. • The crown appears to feature the Omega logo.
Case and Dial Design
The watch is presented in a 40mm stainless steel case characterized by its twisted lug geometry. The case is finished with a brushed bezel and is paired with a sapphire crystal. The winding crown on the side of the case bears the Omega signature. The brushed gray dial incorporates printed Arabic numerals at the 3, 6, 9, and 12 o'clock positions. The hours are further defined by luminous triangular indices. A railroad-style minute track encircles the dial perimeter, and the hour and minute hands are matched to the dial's overall aesthetic.
Movement and Performance
The timepiece functions using the automatic Omega Co-Axial Master Chronometer Calibre 8806 movement. This movement is engineered to operate in environments with high magnetic interference, specifically resisting magnetic fields up to 15,000 Gauss. In terms of operational duration, the calibre provides a power reserve of 55 hours. The watch functions as an automatic mechanical instrument designed for daily wear.
Provenance and Condition
The auction description reports the watch as being in as-new condition. The item is sold accompanied by a stainless steel bracelet that features a signed hidden deployant clasp. The model is a modern iteration of a design originally introduced in 1957. The manufacturer first presented this version of the Seamaster Railmaster at Baselworld in 2017.
