Overview

The Omega Aqua Terra Railmaster was produced in the mid 2000s and came in four different sizes: 36mm, 39mm, 41mm, and a whopping 49mm. At that time the large watch trend was reaching its peak, and so one might imagine that the 39mm, 41mm, and 49mm were initially the more popular buys. But, as history would have it, the trend back towards smaller watches in the 2010s has made the 36mm the most sought after size today by collectors. And, due to a short production run of the entire line, it has become a rather difficult watch to attain. Will it reach the pricing and collectibility of a certain other black-dialed sport watch from Rolex that it shares many characteristics with? Time will tell, but for now the 36mm Railmaster still remains a relative bargain for those who have enough patience, persistence, and luck to find one.

Near Mint
:
Case has only a few superficial hairlines. Lugs are thick, full, and sharp with superb finishing. Dial, hands, and lume may have micro imperfections visible only with a loupe.

Case: The case is in absolute mint condition, with virtually no signs of wear outside of a few small hairlines. The twisted lugs are nice and sharp, and retain excellent definition between brushed and polished surfaces. The polished bezel is very clean, and blemish-free. The case back engravings are deep, sharp, and clear.

Dial, Hands, & Crystal: The dial and hands are minty with no signs of aging and fully functioning Super-LumiNova. The front crystal contains a very small mark on the underside at the 8 o'clock position that's likely a tiny scratch to the AR coating.

Bracelet/Strap: The fully linked Omega stainless steel bracelet shows no stretching and practically no signs of wear, with a sharp Omega logo at the clasp.
