Dive Style Watches Explained: Looks vs Ratings

Walk into any watch shop and roughly a third of the men's watches on display will look as if they were built for scuba diving: a thick rotating bezel with a 60 minute scale, fat luminous markers, a screw down crown guard, a solid steel bracelet. Most of the people who buy them will never wear them deeper than a hotel pool. That is fine. The dive watch is the most popular sports watch design in the world because it is legible, sturdy and handsome, and none of those qualities need water to be useful.

The trouble starts when the look is taken as a promise. A watch can have every visual cue of a diver and still be unsuitable for a swim, and the specification that decides which is printed in small type, if it is printed at all. This guide explains how to read it.

Three kinds of watch that all look like divers

It helps to sort the market into three groups before reading any numbers.

• Dive style watches. They borrow the bezel, the markers and the bracelet. They are sold as a look, and the maker does not promise use in water. Treat them like any dress or everyday watch: fine in the rain, not for swimming.
• Water resistant sports watches. They carry a stated rating, often 100 or 200 meters, which in practice means swimming and snorkelling are fine. Many affordable divers from established brands sit here.
• Certified dive watches. They meet the ISO 6425 standard or the maker's equivalent and are usually marked DIVER'S on the dial. These are the watches built for scuba, with checks well beyond a pressure figure.

How to read a water resistance figure

The most confusing thing about water resistance is that the number looks like a depth and is not one. A rating of 50 meters means the case held a static pressure equal to 50 meters of still water in a test chamber. Moving your arm through water, jumping in or standing under a strong shower creates pressure spikes the static figure does not account for. That is why the rough guidance most brands publish is far more cautious than the numbers suggest:

General guidance as published by major watch brands; always follow the manual for your own watch.

The crown is the weak point

Whatever the rating, it only holds with the crown pushed in or screwed down. A screw down crown, which threads onto the case tube, is the single most important feature on a watch you intend to swim with. Never pull the crown out or press chronograph pushers underwater, and have the gaskets checked after any battery change. Our list of watch care mistakes covers the rest.

What a real dive watch needs

A diver depends on the watch to time their air. That is why the bezel matters: it turns one way only, so a knock can only shorten the timed dive, never lengthen it, and its zero marker is luminous so it can be read in the dark. We explain the technique in what a dive bezel is and how to use one. Add a legible dial in low light, a strap or bracelet with an extension for a wetsuit, and a case that survives knocks, and you have the checklist the certified watches are built to.

Rated divers worth buying

If you will swim, snorkel or dive, buy a watch with a stated rating from a maker with a service network. Three affordable choices stand out.

The Seiko 5 Sports at $350 is an automatic with a rotating bezel and a day date, and Seiko rates it at 100 meters, which covers swimming. It is the classic first mechanical diver. The Citizen Promaster Dive Chronograph, listed at $440 on Citizen's site, is rated to 200 meters and labelled for scuba diving, with a light powered movement that never needs a battery change, which is one less reason to open the case. The Tissot Seastar 1000 40mm at $515 is the Swiss option, rated to 300 meters with a unidirectional bezel Tissot describes as made for timing underwater activity.

When a dive style watch is the right buy

Most people who want a diver want the look: something sturdy and bright with a bezel that clicks, to wear with a t shirt in summer and under a sweater in winter. For that buyer, a dive style watch is a perfectly sensible purchase, and it costs a small fraction of the steel divers it borrows from, which start at about $6,500 at the top of the market.

The Lucky Fours Baretta is a good example of the category done honestly. It has a green rotating bezel around a green dial on a steel bracelet, the color combination made famous by much more expensive divers, and it is sold as a style watch. Wear it to the beach bar, not into the sea. If you want the dive look with an automatic movement, the Demon is a chunky tool diver style with a turquoise dial among its colorways. Neither is the watch to take swimming; buy a rated diver for that.

The short version

Judge a dive watch by its specification, not its bezel. If the maker states no rating, it is a look. If it says 100 meters, you can swim. If it says 200 meters and diver, you can dive. And whatever it says, keep the crown closed and the gaskets serviced.
