I'm a big fan of the classic Speedy, but it was this most recent rendition - the Speedmaster 9300 - that finally pried open the purse strings:
* LOVE the 3-in-2 layout of the subdials, with the hour and minute totalizers combined in one dial that is absolutely intuitive to read - it's just a small secondary clock tracking elapsed time.
* The movement - I really dig the fact that Omega decided to pull out all the stops and design a ground-up state of the art chronograph movement. Column wheel, twin barrels, silicon hairspring / balance wheel. It is by far the most accurate timepiece I own or have ever owned.
* Legibility. Like any white-on-black Speedmaster, this piece offers superb legibility - and increasingly important factor now that I'm needing reading glasses. Don't need them to tell the time on this watch.
* Well, I sure wish it were priced like a classic Speedy.
Oh, and doubling the water resitance over the standard Speedy was a welcome touch as well:
Since adding this piece and a nice gold dress watch, my watch box has been slowly emptying out. I may actually get to a two or three watch rotation for the first time, pretty much, ever.
