SHOULD I GO DIVING IN A DIVE WATCH, OR WILL THAT DRIVE DOWN ITS VALUE EXPONENTIALLY?
First things first: if you’re buying a watch solely for investment purposes, you follow the Comic Book Rule — keep it in a bag (or in this case, a watch-winding safe) and don’t touch it. While watches do hold their value better than, say, cars, they shouldn’t be relied upon to diversify your portfolio. Any damage to your timepiece, underwater or above, will affect the watch’s value, but take note: some watches that have been found in poor condition on beaches decades after they were lost by a soldier — or whoever — have sold at auction for unimaginably high sums. If you are going to dive, though, make sure you check your watch's depth capabilities first.
