Best “Waterproof” Watches for Men (and What the Ratings Really Mean)

Search for “waterproof watches” and you’ll find thousands of listings — but strictly speaking, no watch is waterproof. International standards only allow watches to be described as water resistant, with a rating that tells you how much pressure the case withstood in testing. Understanding that rating is the difference between a watch that survives years of swimming and one that fogs up on its first holiday.

This updated guide explains what to look for and recommends men’s watches with genuine 100–200 m ratings from brands with long track records. It’s research-based: every specification below comes from manufacturer data, not hands-on testing.

“Waterproof” vs water resistant: what the numbers mean

A water-resistance rating comes from a static pressure test. It is not a safe diving depth. As a practical rule of thumb:

Features that keep water out

• Screw-down crown: threads compress a gasket. Always screw it fully home before getting wet.
• Screw-down caseback: generally more secure than a press-fit back.
• The right strap: rubber, silicone, fabric or steel — never leather in water.
• Fresh gaskets: seals age. Have water resistance re-tested periodically if you swim regularly, and after any battery change.

How water resistance is tested

Understanding how a rating is produced explains why it shouldn’t be read as a depth. Manufacturers test watches in controlled conditions: the watch is placed in a chamber and exposed to air or water pressure equivalent to the rated depth, often alongside other checks for condensation and leakage. ISO 22810 sets out tests for general water-resistant watches, and ISO 6425 sets out a stricter, more extensive regime for divers’ watches, including tests for resistance to thermal shock, magnetic fields and shocks, plus requirements such as a time-preset device (usually a rotating bezel) and legibility in the dark.

Real life is less tidy than a test chamber. When you swim, your arm moves through the water; when you dive into a pool, the impact briefly raises pressure; when you step from a hot beach into cold sea, the case and seals contract. Seals also harden with age and exposure to sun, chlorine and soap. That’s why a 30 m watch isn’t a swimming watch even though you’ll never swim 30 metres down, and why we recommend at least 100 m for regular swimming.

Choosing by activity

Everyday wear, rain and hand-washing

Any watch with a 30 m (3 bar) rating handles splashes and rain. If you’ll never swim with it, you can choose almost any well-made watch — including leather-strapped dress watches.

Swimming and the beach

Look for 100 m and a strap that can get wet. The Seiko 5 Sports SRPD and G-Shock DW5600 are good everyday choices. Rinse the watch in fresh water after the sea or a chlorinated pool, and dry it before storing it.

Snorkelling and water sports

Choose 200 m with a screw-down crown for extra margin against knocks and pressure spikes. The Citizen Promaster Diver, Orient Kamasu and Seiko Turtle are built for this kind of use.

Recreational scuba

Use a watch designed and labelled as a diver’s watch, and treat it as a backup to a dive computer rather than a replacement. A unidirectional bezel lets you time a dive; good lume lets you read it in dark water.

Maintenance that keeps water out

Water resistance is a property you maintain, not a permanent feature:

• Pressure-test periodically. If you swim regularly, have the watch pressure-tested from time to time — many owners do it annually, and certainly after any battery change or caseback opening.
• Replace gaskets during servicing. Seals are inexpensive parts that do a critical job.
• Check the crown every time. An unscrewed crown is the most common cause of water ingress on screw-down watches.
• Avoid heat and chemicals. Hot tubs, saunas, steam rooms, solvents, perfume and harsh soaps all accelerate seal ageing.
• Act fast if it fogs. Condensation under the crystal means moisture got in. Stop wearing it in water and have it checked before corrosion starts.

Straps for wet conditions

Rubber and silicone straps are the natural partners for water. FKM rubber, used on many dive watches, is especially resistant to salt water, sunlight and chlorine. NATO-style fabric straps dry quickly and are cheap to replace. Steel bracelets are ideal too, though salt can build up between links — a quick rinse and a soft toothbrush keep them clean. Leather is the one to avoid: water stains it, weakens the stitching and can leave it smelling. If you love leather, keep a second, water-friendly strap for holidays.

Quartz, solar or automatic for water use?

Movement type doesn’t change water resistance, but it changes ownership. Quartz watches need occasional battery changes, each of which means opening the case — so ask for a seal check each time. Solar watches like Citizen’s Eco-Drive avoid routine battery changes, keeping the case sealed for longer. Automatics need no battery at all but should be serviced every several years; the gaskets are replaced as part of a proper service. If you want the lowest-maintenance swimming watch, a solar diver is hard to beat. Read automatic vs quartz watches for the full comparison.

Sizing a dive-style watch

Many water-ready watches are large. Dive watches in particular often measure 42–45 mm with chunky bezels. Before buying, compare the lug-to-lug length with your wrist using our wrist size calculator, or compare two models side by side in the watch size comparison tool. A watch that sits securely and comfortably is also less likely to take knocks in the water.

Myths about water-resistant watches

“A 50 m watch is fine for diving”

No. A 50 m rating describes a test pressure, not a safe depth. For diving, use a purpose-built diver’s watch alongside a dive computer.

“Once water resistant, always water resistant”

Seals age, harden and can be damaged by heat, chemicals and impacts. Water resistance needs periodic checking, especially after the case has been opened.

“Automatic watches can’t get wet”

Movement type has nothing to do with it. An automatic diver rated to 200 m is perfectly happy in the sea; a quartz dress watch rated to 30 m isn’t.

“The crown doesn’t matter”

The crown is one of the main entry points for water. On screw-down crowns, always screw it fully closed; never pull it out underwater.

“Hot showers are fine with a 100 m watch”

Pressure isn’t the issue; heat and steam are. Rapid temperature changes and soap can degrade seals over time, so many manufacturers advise against it.

Our recommendation in brief

For most men who swim occasionally, a 100 m watch with a rubber, fabric or steel strap is enough. If you’re in the water often, choose 200 m and a screw-down crown. Keep the seals checked, rinse after salt water and chlorine, and your watch will stay dry for years. If you’re unsure which rating fits your plans, our interactive water resistance guide suggests a minimum rating for each activity and lists matching watches from our database.

Final word

Ignore the word “waterproof” and look for a real rating: 100 m for swimming, 200 m if you’re in the water a lot. The G-Shock DW5600 is the toughest simple choice; the Citizen Promaster Diver is the easiest to live with; and the Orient Kamasu is our pick if you want an automatic with sapphire.
