But for recreational divers, even technical ones, this isn’t an issue, as we typically do not spend a lot of time in underwater habitats hundreds of meters below the surface. The helium molecules, being extremely small, can make their way into the watch case, and then, when the diver ascends, these molecules expand (due to dropping pressure) and can damage the watch. A helium valve is useful for commercial divers doing very deep saturation diving, where they live in underwater habitats filled with a trimix breathing gas containing helium. You may hear wild stories about an exotic feature called a helium valve. Also, make sure the watch face is clean enough to be easily legible. Most metal bracelets will have an extension function to ensure this. Whether you choose a rubber strap or a metal bracelet is a matter of preference, but make sure that both are long enough to allow you to wear the watch over your wetsuit or drysuit.

Titanium is lighter and more corrosion resistant.

Material is worth considering as well, stainless is good, titanium is better. What should I look for in a dive watch?įirst and foremost, depth rating. If it runs behind, it is necessary to increase the number of TPD by one step.

Then place your watch into the winder and check after a few days how accurate your watch shows the time. And the bezel typically only rotates one way, so if it is accidentally moved, it will only shorten your dive, not extend it, possibly beyond your no-decompression limit. You should select the combined winding mode (CW+CCW) and the minimal number of turns per day (TPD). You rotate the bezel so the zero mark is at the minute hand when you descend, and then you can read the duration of your dive at any time, without having to calculate it. The bezel is marked with minutes up to 60 minutes (typically) to allow divers to quickly discern how long they’ve been down.
