Omega Seamaster Railmaster Co-Axial Chronometer 40mm 220.10.40.20.01.001 

The first Omega Railmaster was similar in concept to the Rolex Milgauss, designed for railway staff whom were working close to electrical fields. Able to withstand 1,000 gauss at the time, it was a proper tool watch built for a specific purpose. 

It features a perfectly proportioned 40mm brushed case, with a stunning vertically-brushed dial which takes on an almost-purplish hue in some lights, which is then accented with vintage inspired lume. The hands are brushed stainless steel with the same vintage lume, and it’s powered by the in-house, Metas-certified Co-Axial 8806 automatic movement.  

This edition is also able to withstand 15,000 gauss, so you probably won’t have to worry about magnetising it working on your computer or going through airport security. Most people would be surprised with how many watches we get through that show some magnetisation, so while on initial impression this may not seem a necessity, believe us it is nice to have. Throw in 150m of water resistance and you’ve got a watch that can pretty much do it all, especially when equipped with its fabulous fully-brushed bracelet.

This particular example was purchased in 2023 and presents in TZ 'Good' condition. The bezel and case sides show a few surface scuffs/scratches, with the reason for the 'Good' rather than 'Excellent' grading on the TZ scale is the presence of a small ding on the outer edge of the bezel near 9. Lugs show some strap change marks. Please see images for full condition details.

Bracelet has enough links to suit a 7.6in wrist, with one spare half link. It shows light desk dive marks throughout.

Remains under balance of Omega warranty, and is keeping COSC time measured dial-up on a timegrapher.

Comes with outer box, inner box, operating instructions, card holder, pictogram card, warranty card dated 2023, Chronometre card, hang tag, Omega pouch and half link for the bracelet.
