How long can water resistant watch last?
For use in water, water resistant watches should be pressure checked every year. The seals should be replaced at least every two or three years. Showering or bathing with your watch on can be bad for it, due to hot water issues, and the fact that soap is a fine level abrasive.
A watch stamped with "Water Resistant" means that it is humidity-protected. It can endure a bit of water splashes from washing your hands or being caught in the rain. However, water resistance does not mean you should swim or shower with your watch on.
Dive Watches
This states that a watch should have a minimum depth rating of 100 meters, which is ok for snorkeling and swimming, but for serious dives, it is best to have a watch that is water-resistant to at least 200 or 300 meters.
You can swim in your watch if it claims to be water-resistant up to 100m, but this still means that it should only be worn for snorkelling at the surface rather than diving. For diving, water-resistance should be up to 200m.
Simply put, a water-resistant luxury watches can withstand contact with for a certain amount of time or under certain conditions, while a “waterproof” watch should, in theory, be impenetrable by water. But the truth is, no watch can guarantee perpetual waterproofness.
All Rolex wristwatches are 'waterproof' to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for the Cellini model. Some Oyster watches can withstand depths of 1,220 or even 3,900 metres.
In 2019, the Omega Ultra Deep Professional was strapped to the exterior of a submersible vessel that touched down on the floor of the Mariana Trench (the deepest trench in the world), clocking a depth of 10,928m and beating Rolex's previous record by just 12m.
Water is the natural element for a Rolex with a metal bracelet, including the salt-water of the sea and ocean. All Rolex wristwatches are waterproof to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for the Perpetual 1908 models.

So what do these markings actually mean? 50m - Water resistant up to 50 meters means it can withstand swimming and cold showers. Hot showers are different as hot water would allow the watch to expand and potentially allow water to get in.
Can Rolex go in swimming pool?
All Rolex wristwatches are waterproof to depths of at least 100 metres for Oyster Perpetual models, and 50 metres for the Perpetual 1908 watch.
Water Rating | Definition |
---|---|
1 ATM | Withstands pressures equivalent to a depth of 10 meters |
3 ATM | Withstands pressures equivalent to a depth of 30 meters |
5 ATM, Swim | Withstands pressures equivalent to a depth of 50 meters |
10 ATM | Withstands pressures equivalent to a depth of 100 meters |

Here, she looks at what happens 100m (330ft) below sea level.
In the simplest sense, a waterproof jacket offers the highest level of protection from rain and snow. While a water-resistant jacket offers a good, but lower level of protection. Though there's a little more to it than that.
In short, “water resistant” describes an item's ability to resist water penetration to a certain degree but perhaps not entirely. On the other hand, “waterproof” technically means that it's impermeable no matter how much time it spends in the water.
Waterproof watches are made to resist water. Regular watches cannot stand different environments. For instance, the extreme humid condition can damage a traditional watch. The materials the watches are made of enables them to withstand various environmental conditions such as excessive dampness.
Air filled watches
In 2022 Rolex introduced the Oyster Perpetual Deepsea Challenge Sea-Dweller (reference 126067), a full ocean depth capable watch with an official depth rating of 11,000 metres (36,090 ft). This watch represented in its launch year the most water resistant mechanical watch in serial production.
The ability to manufacture 1 million watches in a year is an amazing feat. Considering that it's impossible the find a new Rolex in a case at an authorized dealer just shows how popular the brand and their watches are.

What is the deepest humans have gone underwater?
Last year an expedition to the Mariana Trench made history by conducting the deepest crewed dive ever completed as it descended 10,927 metres into the Challenger Deep.
For most swimmers, a depth of 20 feet (6.09 meters) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 meters) when exploring underwater reefs.
There are stories of people who are passionate divers in today's world, who wear both a dive computer and a classic analog dive watch such as a Rolex. They see wearing the Rolex dive watch as a backup in case the computer technology fails, allowing them to continue to have a safe dive.
No matter what, your Rolex will require winding if it is not worn. Modern Rolex watches have a power reserve time between 48 and 72 hours. Older Rolex watches don't have a substantial power reserve time, so they can quickly stop running after just a few hours.
For Rolex watches that do not have waterproof Oyster cases or screw-down winding crowns, you are going to want to keep them away from water and other cleaning solutions to ensure that your watch does not experience any moisture intrusion.
Do not shower or swim with your watch unless it is rated 100m/330ft and has a screw-down crown. Never open, wind or operate the crown while in water. Never press the buttons of a chronograph watch while in water, unless otherwise stated by the manufacturer.
Diver's watches, which are tested in accordance to an ISO test, will be tested to withstand much higher pressure and also temperature changes so you actually should be able to wear your diver's watch in the shower.
Apple Watch Series 2 and later have a water-resistance rating of 50 meters under ISO standard 22810:2010. Apple Watch Ultra has a water-resistance rating of 100 meters under ISO standard 22810:2010 and is EN13319-compliant.
Timepieces are defined as Underwater only when they can withstand a pressure of at least 10 bar, equivalent to the pressure reached at a depth of approximately 100 meters. On the other hand, those watches resistant to a lower pressure, for example 3 or 5 bar, are classified as Water Resistant.
5 BAR / 5 ATM / 50m / 165ft:
Your watch can withstand splashes, shower and is suitable for swimming. It is not suitable for water sports, pool-side diving or sea diving.
Can you wear a 100M water-resistant watch in rain?
You should not take your watch swimming unless it says 10 bar or 100M or more in water resistance. Anything less and basically it can handle humidity, rain, or splashes of water while you're doing the dishes. 2. Warranty does not cover water damage.
You should never wear your Rolex in the shower, bathtub, or hot tub. This is because extreme changes in temperature can actually hurt the gaskets on your watch and leave you in need of Rolex watch repair sooner than you expected.
You should never wear a watch, no matter the rating, in warm or chemically treated water, such as in a hot tub, as both temperature and irritants can damage sealing components and/or compromise water-resistance.
That being said, it is all right to wear your Rolex into the water with you, weather it's a chlorinated pool, hot tub or salty ocean. Your Swiss masterpiece is built like a tank, and the general rule of thumb is; whatever you can handle your Rolex can handle as well.
IP68: The Top IP Waterproof Rating
Technically, the first digit doesn't matter if we're only discussing waterproofing. Since 8 is the highest number on the IP water rating scale, any IP enclosure with a rating ending in 8 offers the best possible waterproof protection.
Green 9. Your child will learn side stroke, shallow dives, surface dives, and ice rescues and continue to develop front crawl, back crawl, breaststroke, and elementary back stroke. Upon completion of this level, your child will be able to complete an interval swim of 400 metres.
By completing the Learn to Swim Stage 5 Award, swimmers will be able to: Perform a flat stationary scull on the back. Perform a feet first sculling action for 5 metres in a flat position on the back.
200 meters/ 662 feet/ 20 bar: Suitable for high impact water sports and aqua diving not requiring helium.
A fathom is a unit of length in the imperial and the U.S. customary systems equal to 6 feet (1.8288 m), used especially for measuring the depth of water.
As you descend into the ocean, pressure increases linearly with depth; there is an increase in pressure of 1 atm for every 10 m increase in depth. So at 1000 m depth the pressure would be 101 atm (100 atm of pressure due to the 1000 m depth, plus the 1 atm that is present at the surface).
Can a watch last 20 years?
Longevity: A quartz watch can last the user for 20 – 30 years, as the electronic components of the watch will eventually wear out. A well-maintained mechanical watch will outlive the original purchaser. High-end mechanical watches can be heirloom pieces, passed down from generation to generation.
Water resistance isn't a permanent condition and can diminish over time.
A 5 bar or ATM / 50m Water Resistant can be subjected to limited water pressure, so you can take a shower or bath and swim. Only watches guaranteed for 10 bar or ATM / 100m can be defined as truly waterproof.
So what do these markings actually mean? 50m - Water resistant up to 50 meters means it can withstand swimming and cold showers. Hot showers are different as hot water would allow the watch to expand and potentially allow water to get in.
Therefore, Swiss-made watches, as well as other equally well-made watches from brands like Bremont, are real lifetime investment pieces and can last for generations when properly maintained and regularly serviced.
Rolex Guarantee
At Rolex, we make watches that are built to last a lifetime. The work we do ensures that our watches can be worn in any circumstance and will stand the test of time. To ensure the precision and reliability of its timepieces, Rolex submits each watch after assembly to a stringent series of tests.
The Watch 1505 /ˌwɒtʃ fɪfˈtiːn ˈəʊ ˈfɑːɪv/ (also named PHN1505 or Pomander Watch of 1505) is the world's first watch.
Cons: While water-resistant, many devices can't survive long in the water. Also, keep your water-resistant device away from the ocean. Many of the coatings used to achieve water protection don't do as well with saltwater.
The resistivity of absolute pure water is 18.2 (rounded) MΩ × cm at 25°C or 0.055 micro-siemens/cm.
Apple's iPhone 12 and iPhone 13 lineups feature the best water resistance rating on an iPhone to date with an IP68 rating. This means that the devices can withstand water up to a depth of six meters (19.7 feet) for up to 30 minutes.
What is the lowest waterproof rating?
5,000mm: This is the minimum rating for a jacket to be called rainproof, however, it won't stand up to much more than a light shower.
All you have to do after diving or a day at the beach is simply to rinse your watch with fresh water to remove any salt and sand deposits: wearing your watch while showering at the end of the day should do the trick. The Oyster case of your Rolex protects it from water and makes it completely dustproof and waterproof.
ATM or “atmospheres” is the amount of pressure a watch can withstand. 5ATM will withstand pressures equivalent to about 50 meters, or 164 ft under water. It is important to note that this is a measure of pressure NOT depth.
They are not designed to withstand warm water. When your watches cools down after the shower, moist air gets sucked into the case. Doing this repeatedly will deteriorate the movement, even if your watch is water resistant or if it's a dive watch with a depth rating of 100 m or more.
During competitions you see sprinters that don't breathe at all over 50 meters while long distance swimmers breathe every second or third stroke. Over a short distance like a 50 meters, your muscles do not need as much oxygen to be able to deliver the necessary power.
