Watch Info
Manufacturer: Omega
Model: Seamaster Aqua Terra "Railmaster" 36mm
Condition: Excellent
Reference: 2504.52
Year: Circa 2008
Box: Yes (Inner box shows typical material deterioration/flaking)
Papers: Yes
Accessories: Complete Set (Inner & Outer Box, International Warranty Card dated 2008, Pictograms Card, and Chronometer Certificate).
Notes: The 2504.52 is a modern cult classic. While the Railmaster was produced in several sizes during the 2000s, the 36.2mm version is by far the rarest and most sought-after by collectors. It is often hailed as the perfect alternative to the 36mm Rolex Explorer, offering a cleaner, date-free aesthetic with the added charm of an exhibition caseback.
Condition Assessment
Overall Condition: Pre-Owned - Excellent. This 2008 example has been exceptionally well-preserved. The stainless steel case retains its original factory lines and sharp, twisted lugs, showing only very light surface swirling consistent with careful, occasional wear.
Dial, Hands, & Crystal: The matte black dial is pristine, featuring the iconic 3-6-9-12 layout. The Super-LumiNova markers and arrow-tipped minute hand are flawless. The domed sapphire crystal is clear with no chips or scratches to the glass or anti-reflective coating.
Case & Bezel: The 36.2mm case is in excellent shape. The polished bezel remains bright and the exhibition caseback is immaculate, providing a clear view of the Co-Axial movement.
Strap/Bracelet & Clasp: The original stainless steel bracelet (Ref. 1575/899) is in excellent condition. It is fully linked, which is rare for a set of this age, and shows minimal stretch. The sliding clasp operates crisply and securely.

Why the 2504.52 is a "Grail" for Many
The Omega Railmaster 2504.52 is a masterclass in understated tool-watch design. During its short production run in the mid-to-late 2000s, the 36mm size was overshadowed by the trend for oversized watches, leading to very low production numbers compared to its 39mm and 41mm siblings. Today, as the market has shifted back toward classic proportions, the 36mm has become the "unicorn" of the Railmaster family.
It occupies a unique niche in Omega's history as a "Railmaster" that is technically part of the Aqua Terra line. This gives it the robust 150m water resistance and the elegant "twisted lug" case design of the AT, but with the sterile, military-inspired dial of the historic CK2914 Railmaster. Powered by the reliable Calibre 2403—the no-date version of the pioneering 2500 Co-Axial movement—it represents a pivotal moment in Omega's mechanical rebirth. Finding a complete set with a 2008 warranty card and full links is a rare opportunity for any serious collector of neo-vintage Omega.
