Railmaster 60th Anniversary Trilogy Edition. My first Railmaster was the 36mm 2504.52 with stainless steel bracelet. But I ended up selling it, and later regretting it. Almost impossible to find. Nevertheless, my mind was always on "What if Omega did a reissue or similar of the 1957 original Railmaster!?" I absolutely craved that watch, and had neither the funds nor the knowledge to get a vintage model. For a few years, I simply put it out of my mind. In 2017, when Omega announced the Trilogy series, I could not believe what I was seeing. For the very first time ever, a dream of mine actually came true. This is the one I would keep, if I was to have only one Omega. I love it on both the stainless steel bracelet, and the Omega leather strap which I came across at the Omega Boutique:

The Railmaster is such an iconic member of Omega history. The fact that it was first made actually for railroad use, and with antimagnetic properties, and now with the latest antimagnetic movement, is amazing tribute to the original alone. Not to mention the perfect replication in almost all details. Only the movement is updated and the crystal is sapphire instead of acrylic. Such a grand piece!
