“stopped working after my first dive”

“I previously rated this watch as 4 stars. Now that I have taken it diving on one dive it has ceased to work. It arrived as a factory reconditioned watch (not advertised by Sierra Trading Post as such). One would think that the factory would have done a pressure test before sending it back out. I only took it to 35 feet. No water or condensation inside the crystal, but the watch no longer runs. It stopped when I got back to the surface.”
