For all "24" fans out there... the watch that Jack Bauer wears in season 5 is a "Special Ops". Here is the link to their watches.
Initially the watch he used in the series (at least season 1) was a standard Submariner. The quality of the pictures is so appalling that I refuse to post them here (guys, do something about it!). In spite of being quartz they are cool watches none the less.
p.s. Thanks Park!
