First off, spring for the titanium version. It is well worth the extra money. I was unsure until I put it on my wrist. Wow, what a difference! At the very last minute, I decided to order the titanium version (mostly because the SS version was not available from Amazon it came from another seller) and am I ever glad I did. I "thought" that I wanted my watches to be heavy and thus would be OK with the stainless version but I was most certainly wrong. The titanium version is so lighteweight it is like nothing else I own. It is a pleasure to wear.

Also, contrary to what has been posted by another reviewer, this watch is totally 100% fine for recreational (aka PADI) diving. I have had it down to 100 feet with no issue what-so-ever. It is rated to 200M (or 600 feet). Most recreational diving is limited to 120 feet so you are well within the boundries of the watch. Anyway, I plan to continue using mine for diving and I do not expect there to be any issue.

The neatest feature of this version (only on the 3rd generation of this model) is the radio self correction. In short, the watch "phones home" to the atomic clock in Boulder, Colorado every morning at 2AM and self corrects the time to the hundreth of a second. Anytime I have checked, it has never been off by more than 2 seconds, even 23 hours after correction. So the watch is accurate to 2 seconds per day but self adjust every 24 hours to maintain this accuracy.
