This is the desirable smaller **36mm Omega Railmaster** (#**2504.52**). It’s a great size for my 6.6” wrist, with surprisingly bright lume. I purchased this one just over two years ago from Bernard Watch ([listing](https://www.bernardwatch.com/Omega/Seamaster-Railmaster-Chronometer/OMG3718)) and have worn it in rotation (examine photos & videos carefully!). From the case number I’d guess it to be from \~2007? Terrific piece–I’ve really enjoyed this one, a great Explorer alternative–but have an incoming piece, so one-in out-out rule. **Size**: 36mm x 11mm thin x 44mm lug to lug x 19mm lug width **Features**: Dark charcoal dial, sapphire crystal dial, superluminova hands & markers, screw down crown, Omega co-axial 2403 movement (base cal.2500) on an original Omega 1575 stainless steel bracelet with 899 end links that will fit up to approx 6.75’ wrist. **Service history unknown**. **No original box or papers**. **Timestamp**: [https://imgur.com/a/4majh2d](https://imgur.com/a/4majh2d) **Photo Gallery**: [https://imgur.com/a/lMqhTX2](https://imgur.com/a/lMqhTX2) (pardon dust & fingerprints) **Videos**: [https://imgur.com/a/iuey8hA](https://imgur.com/a/iuey8hA) **Price: $4,100** includes insured shipping, with tracking, signature required, from Chicago to CONUS only **Payment Method**: Zelle only. And you **must have positive transaction history** here on WatchEx. **Trades? NO TRADES** please! **Interested?** You must **COMMENT** first in this post, then send me a **CHAT** message **About me:** Have done many sales here all with good feedback; and I am also an established buyer/seller on WatchUSeek with strongly positive feedback there (same username). Please examine photos closely to judge condition for yourself and ask questions as this is an approx 15 year old used watch with signs of wear, it is not perfect, and a final sale “as is” with no returns, warranty or guarantee expressed or implied.
