Water Resistance is a must-have trend in watchmaking industry. Maximum brands offer the water resistance features in the timepieces offered by them. Most of us prefer buying watches that possess the water resistant feature in spite of other excellent features integrated in the watch. But very few of us actually know the real essence of Water Resistance.

We are sure you must be wondering what the Water Resistance feature could contribute in a timepiece excluding the watch’s resistance in water! Fret not, as InfiniteShopping is here to your rescue! We will give you the entire lowdown on everything you could possibly wish to know on Water Resistance in our ‘Watch Out! Water Resistance Guide!’ Read on & know your watch the smart way with our customized set of questions created just for you!

What is Water Resistance in Watches?

Water resistance is a seal stamped on the back of a timepiece indicating its water resistant competence. It signifies the watch’s resilience against the ingress of water. The water resistance seal is generally flanked by an indication of the static test pressure on a sample timepiece that was exposed in a leakage sample test.

How do I know if my Watch is indeed Water Resistant?

You need to check the back of your watch in case it possesses a seal or stamp of Water resistance. As per the ISO 2281 an ordinary timepiece possessing water resistance needs to undergo a pressure test with the standard markings & seal indication on the watch. According to the ISO 2281 Horology – Water-Resistant Watches standard, water resistant seal on timepieces also need to define the test duration, the water temperature in testing along with various other parameters.

How do I know about my Watch’sWater resistant competence?

A watch’s water resistant competence is indicated in terms of meter or ft. These depth indication or pressure indication in meters or ft. is indicated as per the pressure test result on the sample timepiece conducted by the manufacturers.

My watch indicates a decent Water Resistant Competence. Can it sustain the same density of pressure for a prolonged period?

The answer to this question is a big No! In spite of an excellent water competence stated on the watch back, watches should not be exposed to the indicated pressure for a prolonged period. An extended exposure could cause severe damage to the exteriors of the watch. For instance, a watch possessing water resistance competence of 40m should not be used for a persistent period in swimming & other vigorous water activities. The watch will not be able to sustain that extent of pressure.

What are the standards of Water Resistance in case of Diver’s Watches?

The ISO 6425-Diver’s Watches define the standards of water resistance in diver’s watches. The ISO 6425 define diver’s watches as ‘A watches that is designed to withstand diving in water at depths of at least a 100m & possessing a system to control the time’. A diver’s watch need to be tested in static or still water under the pressure of 125% of their stated resilience, in order to check for their competence. The additional 25% pressure is conducted to ensure a safety margin.

My watch has a seal saying it’s Waterproof instead of Water Resistance. Will it make any difference?

The ISO 2281 Horology-Water-Resistant watches prohibits the use of the term Waterproof which is adopted by many countries worldwide. This rule was initiated in the 1960s, on the suggestion of several government organizations, one of them being the Federal Commission in the US, while investigating the accuracy & precision of the timepiece sealing & marketing.

How do I know if my watch’s Water Resistance seal is Authentic?

No watch can possess a Water Resistant Seal unless it is approved by the ISO 2281. So in case you are wondering if your watch possesses an authentic Water Resistance seal, you can check for the same with the brand of the watch. Maximum renowned brands are approved with the ISO 2281 when it comes to their Water Resistance Seal & competence.

What are the various Water Resistant Levels & what is their degree of Competence?

Water Resistance levels & their degree of competence is varying. For your convenience we have enlisted the different levels of water resistance with their relevant degree of sustainment as per the ISO 2281 & ISO 6425 Standards.

Water Resistance or depth capacity 30m:

Appropriate for ordinary use. Splash & rain resistant. These watches are not suitable for vigorous activities like swimming, snorkeling, fishing & miscellaneous water related activities. Not suitable for diving.

Water Resistance of 50m:

Apt for water activities like swimming & white water rafting. Inept for snorkeling, fishing & other vigorous water related activities including prolong water exposure. Not suitable for diving.

Water Resistance of 100m:

Suitable for recreational water activities like surfing, sailing, snorkeling & swimming including water sports. However, these watches are not suitable for diving.

Water Resistance of 200m:

These watches are appropriate for professional marine/water activities & vigorous surface Water sports. However, these watches are not suitable for diving purposes.

Diver’s Water Resistance of 100m:

This is the minimum water resistance requirement as per the Diver’s Watches-ISO 6425 standards. This watches are appropriate for scuba diving although inept for saturation diving. The Diver’s 100m or 150m water resistant watches are usually older watches.

Diver’s Water Resistance of 200m or 300m:

These watches once again as per ISO 6425 are suitable for Scuba Diving but unsuitable for Saturation diving. The water resistance competence of 200m or 300m is the emblematic ratings of a standard diver’s watch.

Diver’s Water Resistance of 300+ m for Mixed-Gas Diving:

These watches are apt for the mixed gas (helium enriched environment) and saturation diving. These watches are especially designed for mixed gas diving & possess a marking reading ‘DIVER’S WATCH L M FOR MIXED GAS DIVING’ to point out their water resistance competence in mixed-gas diving. This is the indication that these watches have to possess as per ISO 6425.
