I have had this watch for over 20 years. I don't wear it all the time (dives, when my regular watch breaks, and weekends). I've had it down to 150ft with no problem. The large timing ring is easy to rotate even with gloves. It keeps perfect time and still has the original strap! It's one of those rare time pieces that seems to improve with age. The case is so massive that it feels like it could be used to drive nails (though I wouldn't recommend it, as rugged as it is).
