Watch Water Resistance | A Helpful Guide To The Rating

Watch Water Resistance | A Helpful Guide To The Rating

While hand washing or showering is a huge murmur of alleviation for watch proprietors all over, the capacity to jump directly into the water, or not agonizing over your watch getting wet. What does watch water-resistance really mean with regards to watches, and how might you know what your watch can withstand?

In order to know the exact thing your watch can withstand, there are several different rating frameworks that will assist you. However, this article will cover the three distinct ratings and standards.

  • BARs or ATM/Meters
  • ISO – International Organization of Standards
  • IP Code or IP Rating

By uncovering the phrasing and ratings so you can know definitively what to think while purchasing your next watch, here in this article, we will separate every one of the fantasies of water-resistance watches.


On a watch back that shows how much water pressure a watch can endure, water-resistance is the stamp imprinted. In BARs and ATM or atmosphere and additionally more generally in depth and meters, the tested pressure can be expressed.

With a water resistance rating of 30, 50, 100, or even 200 meters, or 200m, the standard watch will be named. Then, at that point, from the ISO or the International Organization of Standards, you have an additional a degree of standardization.

To pay consideration, there are two sorts of ratings that are ISO 2281 and ISO 6425, the diving watch standard.

Watch Water Resistance chart

However, you quickly accept this implies that your watch is water-resistance at a depth of 30 meters, which is completely not correct at the point when you see a marking on the rear of your watch that says 30m water resistant.

With standard hand washing, an occasional rain shower, or puddle splashing while at the same time riding your bicycle, a watch marked at 30 meters is simply water-resistance to deal. To deal with swimming, diving, or in any event, showering and bathing it is not sufficiently resistance. Thus what do these markings really mean?

  • Water Resistant 30 Meters / 3 Atmospheres / 3 Bar

When in reality, 30m means that your watch can withstand water droplets and quick hand washing.

  • Water Resistant 50 Meters / 5 Atmospheres / 5 Bar

It can withstand swimming and cold showers. To expand and possibly permit water to get in, hot showers would permit the watch and are different as hot water.

  • Water Resistant 100 Meters / 10 Atmospheres / 10 Bar

It means it is possible to swim or dive with the watch on, however it is not suitable for diving.

  • Water Resistant 200 Meters / 200 Atmospheres / 20 Bar

It usually means you can dive with your watch on. However, the water-resistance will become less effective as the covers are exposed to different elements by passing time.

  • Water Resistant 300 Meters / 300 Atmospheres / 30 Bar

It is appropriate for all high-impact water sports, scuba-diving and saturation diving.

  • ISO – International Organization of Standards

For water resistance, ISO or the International Organization of Standardization involves various tests led on watch faces and other electronic and mechanical parts.

While buying a watch, there are two essential standards of ISO to see.

  • ISO 2281 Water Resistance Standard: All watches that are not diving watches.
  • ISO 6425 Divers Watch Standard: Standards especially for diving watches.

ISO 2281 Water Resistance Standard Test

While estimating the water-resistance of watches, this standardized test precludes the term waterproof to be utilized. Additionally, there is a breaking point to how much water pressure a watch face can deal with.

Under any conditions, which are definitely not the situation, waterproof infers that a watch will not spill. In the year 1990, the ISO 2281 test was developed and updated in 2010 and is just intended for watches made for common regular daily use.

For these tests, the important standards cover:

  • Water resistance
  • Reaction to Temperature
  • Reaction to Condensation
  • Reaction to Pressure

ISO 6425 Divers Water Resistance Standard Test

As far as possible, Diver ISO 6425 takes the testing of the standard watch. However, you should rest assured your watch will execute as advertised while financing in an ISO acquiescent watch.

The explicit features and meets explicit standards that any watch being utilized for jumping ought to are incorporated in your watch. It intends that before you take your new 300m watch head into the water on your wrist, it is already been 375 meters and back without any issues in viable terms.

For these tests, the important standards cover:

  • Resistance to Salt Water
  • Reliability Under Water
  • Reaction to Condensation
  • Reaction to Extreme Water Temperature Changes
  • IP Code or IP Rating

The IP Code depends on a series of tests allocated a rating similar to BARs and meters and ISO. The level of security given by casings and electrical enclosures in areas against interruption, dust, accidental contact, and water is rated by IP code. With the letters I and P, this rating is composed, then two digits, followed by two additional digits. With solids, the initial two digits have to do.

There is just an IP followed by an X as the first digit is not as intensely applicable to our watch choices as water is, on account of most watches.

The kinds of humidity, water, and pressure, the numbers following the X will tell you exactly, your watch has been tested to endure. With it, to go somewhat deeper and get a little intellectualist, the IP code estimates water resistance in bars and pressure, and coming up next is their rating system in brief:

  • IPX: No protection.
  • IPX1: Comprises protection against vertically falling droplets, such as condensation. When water is falling onto the upright case, guarantees no damage or interrupted functioning of components will be experienced.
  • IPX2: From up to 15°, protection against water drops.
  • IPX3: When the case is upright, protected against a water spray of up to 60°.
  • IPX4: From all directions, protected against water splashes. For at minimum ten minutes with a wavering spray, the case has been tested.
  • IPX5: Comprises protection against low-pressure jets of water directed from any angle, limited entrance allowed with no dangerous effects.
  • IPX6: The protection against straight high-pressure jets.
  • IPX7: At depths among 15 cm and 1 meter, limited entrance allowed with no dangerous effects, protection against full involvement up to 30 minutes.
  • IPX8: Under higher pressure, such as greater depths, protection against prolonged involvement. Such as temperature fluctuations and flow rates, precise parameters of this test may include these factors, depending on apparatus kind, typically set by the manufacturer.
  • IPX9K: The protection against high-pressure, high-temperature jet sprays, wash-downs, or steam-cleaning processes.


As a watch client and purchaser that truly relies upon your requirements. What is the best rating system? To know whether you can swim in your 30m watch, you currently realize the response is no and that the ratings for the watches you can swim with start at 100m or that you really need at least an IPX7 to go swimming with your loved ones. Anything that makes the biggest difference is that you are informed and can, initially, know whether a watch is evaluated for what you really need.

Frequently Asked Questions (FAQs)

  • How water resistant should a watch be?

  • What does water resist mean on a watch?

A watch printed with “Water Resistant” means that it is humidity-protected.

  • Can you swim with a 50m water resistant watch?

Sure, you can swim with a 50m watch, but it is suggested swimming is kept to a minimum to avoid long-term damage to your watch.

  • Can I shower with 100m water resistant watch?

If the watch is rated 100m or 330ft and has a screw-down crown then shower or swim with your watch, otherwise not.
