This purchase is my second H3 type six watch. The first has had several battery changes, and through years of wear the bezel paint worn away and the tritium decaying through it's expected half life, but it's still ticking. The new design is a little bit larger, and I upgraded to the day/number window from just the number. The secured setting knob is a nice upgrade as well. I expect to have this watch for years, with little more than battery changes for maintenance. This HE watch series is worth the price, and definitely worth it when there is a discount find.
