Seiko Prospex SPB383
Arizona Fine Time sent me the watch quickly, gave me a nice discount too. It's a very fine watch, has to be the best Seiko I've ever owned and I have many Seikos.

Watch arrived fast, alignment was good. Keeps great time (approximately 2.5 seconds fast a day) and just plain looks good. A very nice everyday wear option. Wears smaller than the measurements would suggest, and is not overly thick. Overall a very nice watch.
