Understanding Watch Water Resistance Ratings and ATM Standards Explained

The waterproof rating standard isreplica watchesIt is also one of the criteria that determines whether a watch is suitable for use in underwater activities. When buying collectible watches, knowing the meaning of waterproof rating standard can better protect your watch from being damaged by inappropriate environment. In this article, we will give you a detailed introduction to collectible watches waterproof rating standards and their meanings.

waterproof rating

The water resistance of a watch is usually measured by one unit - water pressure (usually measured in ATM). "1ATM" means that a watch can withstand 1 atmosphere of pressure in still, shallow water, which is equivalent to a depth of 33 feet or 10 meters. Therefore, the higher the water resistance rating, the better the watch's ability to be used in deeper and tougher underwater environments.

Waterproof rating standard

The following are common waterproofing rating standards and their meanings:

• 30M / 3ATM

collectible watches can only withstand the waterproofing needs of daily life, such as washing hands or encountering light rain. It is not suitable for use in underwater activities.

• 50M / 5ATM

Not suitable for prolonged swimming and soaking in water, but can cope with daily water operations such as hand washing and rain showers.

• 100M / 10ATM

Suitable for underwater activities such as swimming and shallow diving, but not for deep diving or high-speed water activities.

• 200M / 20ATM

Suitable for shallow diving and water sports such as surfing and sailing, but not for deep diving.

• 300M / 30ATM

Suitable for deep diving, but not for professional or deep sea divers.

• 500M / 50ATM

Ideal for long deep dives and underwater sports.

It should be noted that although the water resistance of collectible watches is tested at the time of production, the water resistance will gradually diminish due to changes in the environment and conditions of use. Therefore, the watch should be returned to the watchmaking company for water resistance testing and maintenance on a regular basis, especially before engaging in underwater activities.

summarize

The above is a detailed description of the water resistance rating standards for collectible watches. Knowing these standards can help you choose a watch that suits your needs and protect the watch from unnecessary damage. When using a watch, you must pay attention to protecting its waterproof performance to ensure its service life and accuracy.
