I’ve seen these things around but never really was interested. It’s an ana-digi watch from Omega that was quite popular a few years ago but is not kind of show its age. WatchReport has a, well, report:

Say Hi to the Omega Speedmaster X-33. Introduced in 1998, this is one amazing watch. Omega literally flight (and crash) tested it with NASA and military pilots, experimenting with several design iterations before settling on and shipping two commercial versions. It was designed for pilots and space flight, and is rated by NASA for the mission to Mars. Without a doubt, this is one of the coolest and most interesting analog-digital watches ever made.
