Edit: 5 years later, the watch still works and looks great! It has run perfectly with daily wear this whole time, until I submerged it in water recently and water got inside (the waterproof seals only last 2-3 years, apparently). I had a full service performed on it ($750!!) and now it is good as new. Beware the high cost of repairs on these watches though, yikes.

The Omega Speedmaster is one of the most iconic watches in history, since it was chosen by NASA (over Rolex, Breitling, etc.) as the most space-worthy watch available, and was the first watch worn on the moon. That was 50 years ago, and the fact that the Speedmaster still looks cool is an incredible testament to what a timeless design it has. Still though, the original Speedmaster ("Professional" it was called) does look a bit dated. This watch solves that problem with a curved sapphire crystal (shinier and harder than the shatterproof plastic they used in space), and beautiful polished markers, emblems, and subdials. The pictures don't do it justice, as this watch looks thoroughly modern and beautiful, while still retaining the timeless Speedmaster style. Go look at it in person at a jeweler. I also appreciate that it is 40mm --That is still large, but not stupid-huge like many other watches these days. The huge watch fad will pass soon, so you might regret buying something too large.

This watch has the Valjoux 7750 movement, which Omega modified to meet full COSC Chronometer accuracy standards, so it is also even more accurate than the original Moonwatch. The Speedmaster Date 3210.50 just has no downsides. It looks good with a business suit, or with shorts and a t-shirt. Buy this watch and enjoy it for another 50 years.
