Water Resistant vs. Waterproof Watches

Water resistance is one of the main qualities that watch buyers look for in luxury watches. People come into contact with water daily, after all, and a watch must be able to withstand these day-to-day activities. If you’re in the market for a luxury water resistant or waterproof watch, then make sure you first know the difference between a water resistant watch and a waterproof one. If you intend on taking your watch for a swim or dive, then it’s especially crucial that you know the difference so that you don’t break your luxury watch.

What Is A Waterproof Watch?

You’ll notice that luxury watches are rarely labeled as “waterproof.” Instead, they have a label on the watch dial indicating water resistance and a number of meters. This is because no watch is truly waterproof. “Waterproof” implies that a watch will never leak, under any circumstances, but the truth that if put enough water pressure on it, any watch will leak. That doesn’t mean that near-waterproof watches don’t exist, though. Rolex’s Oyster Perpetual Rolex Deepsea Challenge, for instance, has been proven waterproof up to 12,000 meters or 39,370 feet.

When shopping for a watch for your needs, don’t look for a waterproof watch. Instead, look for a water resistant watch whose water resistance depth matches your intended use.

How To Read The Water Resistance Rating

Now that you know the difference between water resistant and waterproof watches, let’s take a look at water resistance ratings and what they mean. Water resistant watches will have a depth rating on them, but do you know what the numbers really mean? While you might expect that a watch with 100M/330 ft water resistance can be used for scuba diving up to 100M, this is actually not the case.

In fact, a watch with 100M water resistance passed a leakage test at a static test pressure of 100M, but this does not mean that the watch will withstand leakage if used for extended periods of time at such a depth. The watch is actually only suitable for use at a fraction of its indicated rating. Watches with a 100M water resistance rating should actually only be worn for shallow water swimming, and not diving.

Water Resistance Ratings

You can view our full water resistance guide here, but below is a list of common water activities and the water resistance ratings to look for in a water resistant watch for those purposes.

  • Non-Water Resistant: The watch can’t be exposed to water at all, not even for cleaning.
  • 50M/165 ft: The watch can be worn while showering.
  • 100M/330 ft: The watch can be worn while swimming in shallow water.
  • 300M/1000 ft: The watch can be worn while scuba diving.
  • 1000M/3000 ft: The watch can be worn for deep sea diving.

Though no watch is truly waterproof, the difference between water resistant and waterproof watches gets smaller as the water resistance depth is deeper. Get a well-made watch with a high water resistance rating for a practically waterproof luxury watch!

Standards of Regulation

ISO 2281

In 1990, the International Organization of Standardization issued its standard for rating water resistant watches. It has since been adopted by many countries. The ISO 2281 standard is a thorough test that accurately and meticulously determines the water resistance of a watch. It subjects watches to water pressure resistance tests, condensation tests, and air resistance tests, among others. These tests are performed on a random sample from each batch of watches.

In addition to creating this template for rating water resistant watches, the International Organization of Standardization also bans the use of the term “waterproof” in describing a watch.

ISO 6425

ISO 6425 is a standard that regulates divers’ watches. Introduced in 1996, the rating is given to watches that can withstand depths of at least 100M. The watches are put through reliability tests, condensation tests, salt water tests, and pressure tests, among others. Divers’ watches must be especially hardy as they are relied upon in crucial life-or-death situations underwater.

Furthermore, certain divers’ watches will also be approved for mixed-gas diving (diving with assistance from a diving chamber). These will indicate “For Mixed-Gas Diving” next to the watch’s water resistance rating.
