5 Best Watch Style Dive Computers in 2022


A diving computer is a device used by divers to measure their dive time and depth, as well as to control their ascent and descent rate. The most basic function of a diving computer is to track a diver’s dive profile, which is the time it takes for a diver to descend from the surface to the bottom of a dive, as well as the time it takes for a diver to ascend from the bottom of a dive back to the surface.

We are going to be reviewing the top 5 best watch-style dive computers. We will take a look at which one is our favorite, what features they have. Hopefully, this will help you make an informed decision on your next purchase.

Factor to Consider When Choosing Dive Computers

Battery

Dive computers are equipped with user-replaceable batteries. For the purpose of this review, we have included dive computers that have rechargeable lithium-ion batteries.

Lithium-ion batteries can be recharged by plugging into a USB port or AC/DC adapter via your computer or another device capable of supplying power. An advantage to choosing a dive computer with a removable battery is that you don’t need to send it to the manufacturer for changing the battery every two-three years if it’s still in good working condition. You can save money on shipping by buying a replacement battery locally instead.

Depth Gauge

The best depth gauges are highly reliable, accurate, and quick responding sensors that provide diverse critical information about the current depth and water pressure at any given time. The best dive computers are equipped with depth gauges that provide an instantaneous reading of real-time depth up to the maximum allowed diving depth of the diver.

Alarms

The diving computer should have preset alarms for specific functions. It is important that alarms are loud enough to be heard by divers in case they are engaged in an underwater activity or neutral buoyancy exercises, or if their earphones malfunctioned.

The alarm on a dive computer may be set off when a diver reaches certain depths, depths below certain levels, time duration set before an ascending ceiling is reached, etc.

Depending on the preferences of the individual diver you can either choose between audible alarms or visual ones. Visual alarm options include LCD screens while audible alarm options include vibrating alerts.

Computer Interface

The user interface on a dive computer is really what makes it easy to read and understand. The display should contain large fonts that can easily be seen underwater, as well as buttons that can be pressed even with gloves on or if there’s water between your fingers. It is recommended that the dive computer has an LED backlight for better display clarity in dark or low-light conditions.

There should also be a changeable contrast and brightness adjustment to make the screen clear and easy to read no matter what environment it’s in. Some dive computers can even be set underwater to allow easy viewing of information without having to pull away from your task at hand.

Graphical Display

A dive computer with a graphical display is definitely more universal than one that just displays numbers because there are many different types of divers who will be using the same device – each with their own personal preferences for preferred reading methods.

Any information displayed on the screen must be easily understood by diver regardless of their ability level, age, or time spent underwater. The best watch-style dive computers can show several different graphs and information at once, not just one.
