The phrasing ‘diving watches you can actually dive in’ probably sounds with a tautology. Of course you can dive in diving watches. Well, yes and no. It all depends on what you humble by ‘diving’. If it’s splashing around in a snorkel then that’s normally fine. When the tank and wetsuit come out, most nosediving watches need to stay on dry land.

That’s because a lot of what constitutes a professed diving watch is aesthetic. The unidirectional bezel, the case determine, perhaps a rubber strap; all hint at underwater adventures, yet the seniority of men who buy them don’t go deeper than their bath. For those who do, most significant is the ability to plumb the depths without bursting under the twist someones arm.

Watch water resistant ratings are tested in still, freshwater. But add salt and tendency and the pressure increases. Which means your 30m resistant tend isn’t one to strap on to explore shipwrecks.

For proper scuba diving, you lack a watch with a water resistance of at least 200m, or 20 heavens (one atm is the pressure at sea level; the deeper you go, the more pressure the water utilizes, the higher it climbs). If you see the word DIVERS printed on the dial, then it’s been independently check up oned to the promised depth, plus 25 per cent. If not, then you’ve merely got the manufacturer’s word. Which is best taken with a dram of saltwater.

Innumerable diving watches, such as the Oris Carl Brashear Fixed Edition, are only suitable to 100m. For serious divers, that’s an precious way to not know the time underwater. So if you don’t want your watch to repose with the fishes, strap on a timepiece that isn’t so shallow.
