How much is 10 ATM?
Many watch enthusiasts come across the term "10 ATM" in watch water resistance descriptions. What does this abbreviation mean, and how is it relevant to the everyday use of watches? In this article, we'll explore what 10 ATM signifies and its connection to watch water resistance.
ATM and Water Resistance:
ATM stands for atmospheric pressure, although historically, the term was used to measure the depth of a column of water that pressure creates. Currently, ATM is used to indicate the level of water resistance in watches. 1 ATM corresponds to the pressure at a depth of one meter underwater.
10 ATM in Practice:
If you have a watch labeled 10 ATM, it means it is resistant to a pressure of 10 atmospheres, equivalent to a depth of 100 meters. This value should be sufficient for everyday activities like swimming, surface diving, or showering. However, it is not recommended to use watches with a 10 ATM rating for deep-sea diving or other high-pressure water activities.
Misconceptions:
It's essential to realize that water resistance in watches is not constant and can decrease due to wear, aging, or improper maintenance. Assuming that a watch with a 10 ATM rating is automatically suitable for deep-sea diving can lead to watch damage and the loss of water resistance warranties.
Precautions and Maintenance:
To ensure optimal water-resistant properties of watches, it is recommended to follow these precautions:
-
Avoid using buttons underwater: Pressing watch buttons underwater can lead to water penetration into the watch mechanism.
-
Regular maintenance: Regular inspection and maintenance of watches by a professional can prevent sealing issues and maintain water resistance.
-
Gentle cleaning: After exposure to seawater or chlorinated water, rinsing the watch with clean freshwater and allowing it to dry is advised.
Conclusion:
10 ATM on a watch signifies resistance to a pressure equivalent to a depth of 100 meters. However, it's crucial to be aware that watch water resistance is not permanent, and proper maintenance and precautions are necessary to retain this property. With proper use and maintenance, watches with a 10 ATM rating can provide reliable water protection for most daily activities.
