The initial set-up involves programming the perpetual calendar, setting the watch to automatically adjust to daylight savings time changes, and adjusting the rubber strap. Only the last item is at all tricky, as there are no instructions; I figured out that the strap actually must be cut (use a sharp razor blade or x-acto knife) to fit, but be careful: you can make it shorter, but you can't make it longer. (I deduct one star because I think this is a poor design and the manual should include instructions for adjusting the strap length, given that most people will not immediately recognize the need to cut it.)

Once the watch is set up, it will never need a winding or battery change, will never need to have the time or date reset, hell it won't need you to do anything unless you go to a different time zone - and that is a super easy adjustment with this watch. The sapphire crystal should be virtually scratch proof, and the water resistance rating is a solid 200m.

My watch easily picks up the atomic clock signal each night, as I am under 400 miles from the transmitter in Fort Collins.

The only caveat about this watch: it's pretty big. Heavy, too.

Update on 5/1/13:
I've now had this watch about nine months and like it more than ever. I put on a leather strap, which is more comfortable and stylish. The sapphire crystal is terrific: I have banged it against things a few times and it remains completely free of scuffs and scratches. When I travel between time zones (about 1x per month), the feature that allows quick time zone change is much appreciated.

I have also gotten completely accustomed to the size of the watch - that only took a few weeks, really. While I am still not crazy about the rubber strap, I think the watch's other attributes justify increasing the rating to five stars, so I have done that.
