I absolutely love this watch.  So much so, that my most recent purchase was actually a replacement.  It's great to be able to customize the features displayed while toggling through the modes so you only have the features you use most.  The watch face is recessed well below the housing, so it's tough to scratch.  In fact, my previous watch was on it's second band and the face had yet to get a scratch on it.  I was also successful wearing this watch while scuba diving to ~ 45-47' deep on 4 or 5 dives.  The buttons all functioned, and the watch never fogged over.  However, this brings me to my short list of cons...

The biggest of which, is the reason I needed to replace my original watch after roughly 5 years of use.  I replaced my battery after about 3-4 years of use, and all seemed well.  However, I recently went diving with my watch for the 6th time, and after checking to see how long my descent took (to 25' deep) I was crushed to see that my watch face had fogged over and the numbers were garbled.  Needless to say, by the end of the dive the watch was toast.  About a day later the LCD ink started spreading across the screen.  I'm not sure if Timex greases the o-rings or glues something in place when they install the back or what, but for whatever reason the watch did not live up to the 200 m water resistance after changing the battery.

Some minor gripes are the thickness of the watch face (~ 11/16") and the difficulty in finding replacement bands.  I wound up buying a nice dress watch for wearing under sleeves, as this watch only fits under long sleeve shirts with larger cuff openings.  As far as watch bands go, I managed to track down the authorized parts retailer for Timex and got a new replacement band for my original watch within a week or so for around $10 (if memory serves me right).

All in all, this is a fantastic watch.  It really does take a beating and lives through it - most of the time.  Ultimately, I'd be happier if replacing the battery did not compromise the waterproofing of the watch.  The 4-star review was because of this large flaw after battery changes, but as I said, it still lasted me about 5-6 years.
