Water Resistance
Water resistance is common in watches, but there's more to know. Whether diving, vacationing, or curious, follow expert advice to protect your watch and ensure lasting durability.
Understanding Water Resistance in Watches
Water resistance is a crucial feature in watches, but it is often misunderstood. Many assume that "water-resistant" means a watch is completely waterproof, but no watch is entirely impervious to water. Instead, water resistance refers to a watch’s ability to withstand moisture and water pressure under specific conditions.
Water resistance is measured in atmospheres (ATM), meters, or bars, indicating how much pressure the watch can handle. However, these ratings are often theoretical. For example, a watch rated 30 meters (3 ATM) is not suitable for swimming but can endure minor splashes. Watches rated 100 meters (10 ATM) or more are better suited for water activities.
Several factors contribute to water resistance, including gaskets, screw-down crowns, and tightly sealed case backs, all designed to prevent water infiltration. However, over time, seals degrade, reducing protection. Regular maintenance and testing ensure that a watch retains its resistance, helping protect delicate internal components from moisture damage.

Water Resistance vs. Waterproof: Understanding the Difference
Water Resistance
Water resistance refers to a watch’s ability to withstand moisture and water pressure to a specific depth. Unlike the term "waterproof," which implies absolute protection, water-resistant watches have varying levels of resistance, determined by gaskets, seals, and case construction.
Most watches indicate their water resistance in meters (m), feet (ft), or atmospheres (ATM). For example, 30m (3 ATM) means the watch can handle splashes but is not suitable for swimming. 100m (10 ATM) is safe for swimming and snorkeling, while 200m+ (20 ATM or more) is designed for diving.
Over time, rubber gaskets dry out, reducing resistance. Regular testing and maintenance help preserve a watch’s water protection. Sudden temperature changes, crown misuse, or aging seals can allow water to enter the movement, causing damage.
To maintain optimal water resistance, avoid exposing non-dive watches to excessive water and have them checked annually for seal integrity.
Waterproof
The term "waterproof" is often misused in the watch industry, as no watch is entirely impervious to water. Instead, watches are classified as water-resistant, meaning they can withstand moisture and water pressure to a certain degree.
A waterproof watch would imply absolute protection against water, regardless of depth or pressure, which is technically impossible. Even professional dive watches with high water resistance, such as those rated 200m (20 ATM) or more, have limits. Factors like temperature fluctuations, aging gaskets, and improper crown usage can compromise water resistance over time.
Manufacturers use rubber gaskets, screw-down crowns, and tightly sealed casings to enhance water resistance. However, regular testing and maintenance are essential to ensure continued protection. Deep-sea divers and professionals rely on ISO-certified dive watches, but even these require periodic servicing to maintain their integrity.
To avoid damage, always follow the manufacturer’s guidelines and never assume a watch is 100% waterproof.
