What does 3ATM waterproof mean?
ATM. Withstands pressures equivalent to a depth of 30 metres. ATM, Swim. Withstands pressures equivalent to a depth of 50 metres. ATM, 30m, 100ft: Suitable for everyday use. Can withstand accidental splashes but not suitable for swimming. ATM, 50m, 165ft: Suitable for everyday use and bathing but not for swimming. ATM, 100m, 330ft: Suitable for everyday use, swimming, and snorkeling but not for high board diving or sub-aqua diving.Watches rated at this level handle aggressive swimming, recreational diving, and most water-based activities. However, professional diving operations require higher ratings due to rapid pressure changes.ATM Ratings for Diving Watches A watch with a 10 ATM (100 meters) rating is suitable for snorkeling, while a 20 ATM (200 meters) watch can be used for high-impact water sports and professional marine activity. Watches with a rating of 30 ATM (300 meters) or higher are suitable for professional diving.The number 5 atm in a watch doesn’t mean that it will be waterproof until 50 meters in depth. In a simple explanation, swimming can cause water pressure peaks higher than 50m. This is why you can’t go swimming with 5 atm watches as that number only explains the water pressure up to that number.
Is a 2000 waterproof rating good?
If a garment is 2,000mm waterproof this means the fabric can withstand 2,000mm of water over a day before water will start to penetrate through. The minimum standard for a jacket to be waterproof is 1,500mm so a jacket with a waterproof rating of 2,000mm would be suitable for moderate rain. Jackets rated at 10,000mm are suitable for light to moderate rain and shorter periods of exposure. This level of protection performs well in changeable weather where breathability and comfort are prioritised alongside waterproofing. At 15,000mm, waterproofing becomes more dependable in prolonged rain.These garments meet the British Standard for being waterproof and will keep moisture out during exposure to light rain. They are ideal for a quick dog walk, bringing the horses in out of the rain, getting to and from the stables to the field, or walking around town.
Is 200m water-resistant good?
Watches rated to 200m can withstand substantial pressure from activities such as high board diving, as well as prolonged submersion from scuba/recreational diving. The higher water-resistance rating is usually achieved due to features such as a screw-down crown and caseback. 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.
What does 30m waterproof mean?
Water resistant up to 30 meters, when in reality 30m means that your watch can withstand water droplets and quick handwashing. Water resistant up to 50 meters means it can withstand swimming and cold showers. The term waterproof implies that a watch can’t leak under any circumstance—that no moisture will permeate the case and get into the movement. However, under certain circumstances anything can leak. Therefore, in the watch industry, we refer to a watch’s ability to withstand water pressure as water resistance.
