Before you buy, check the service and support for the watch. I purchased a SEIKO "Orange Monster" in June to use as a backup timer for my computer; after the first dive greater than 60' (apx 20m) with this gear (rated to 200M), I surfaced and found condensation under the crystal. Calls to Seiko, Coserv (thier service center) and local authorized dealers all came to naught ... all failed to service / repair a watch that is still under the original manufacturer's warranty.

So no matter how good you think a watch may be - the service is important unless you want a disposable bottom timer when a battery wears out, or a unit needs servicing.
