The new Omega Railmaster collection represents some of the most technically interesting mechanical watchmaking anyone's doing at any price. These watches at 40mm are a highly versatile size and have attractive vintage inspired styling, while coming in several different variations, so it won't be a struggle to find one that is appealing from an aesthetic standpoint.

However, perhaps the most astonishing thing is what's under the hood for the price asked. The movement is Omega's in-house caliber 8806 and it's Master Chronometer certified: that means it can withstand magnetic fields of up to 15,000 gauss (and probably greater, assuming you can find one outside a physics lab or a neutron star) with a co-axial escapement and a 55-hour power reserve. It also means that in addition to being certified as a chronometer by the COSC, the entire watch is also tested by the Swiss Institute of Metrology (METAS) for water resistance, rate stability under different temperatures, isochronism, and more.

These watches have solid casebacks, which is a bit of a shame, but knowing that you have one of the most technically advanced watches in the world on your wrist, with an escapement designed by one of the most important horologists of the 20th century, is a major consolation for not being able to see it in action. And the prices for these watches are quite breathtaking: just $4,900 on a strap and $5,100 on a bracelet. They're not in stores yet, but they're expected to be available sometime this fall.
