A Guide to Watch Waterproofing Knowledge and Maintenance Skills

When purchasing a watch, you often come across terms related to waterproofing, such as [water-resistant up to 30 meters] [10ATM], or [waterproof watch]. These terms are not just numbers, they delve deep into the core of watch design—the principles of waterproofing. Next, let’s delve into the principles of watch waterproofing and learn how to correctly identify waterproof watches.

The principles of watch waterproofing are primarily based on two aspects: sealing and material selection:

1. Sealing: Waterproof watches typically employ a multi-layer sealing structure, with a crucial component being the sealing gasket, which forms a waterproof seal at the junctions between the case, crystal, crown, and case back, ensuring that water does not enter the interior of the watch.

2. Material Selection: Waterproof watches are usually crafted from corrosion-resistant materials such as stainless steel, and titanium alloy, for the case and strap. Additionally, abrasion-resistant materials are used for the crystal, such as sapphire glass or hardened mineral glass, to withstand the erosion of water, sweat, and other corrosive liquids.

What are the Waterproof Ratings for Watches?The ratings of waterproof watches refer to the pressure that a watch can withstand underwater, with every increase of 10 meters in water depth corresponding to an increase of 1 atmosphere (ATM) in pressure. For example, 3 ATM represents a depth of 30 meters, and 5 ATM represents a depth of 50 meters.


● Basic Life Waterproof (30 meters / 50 meters):30 meters waterproof: The watch can withstand water pressure of about 30 meters depth, is suitable for daily wear, and can resist occasional water splashes and sweat.

50 meters waterproof: It is suitable for short periods of shallow water activities, but should not be submerged for extended periods such as diving or swimming.

● Advanced Reinforced Waterproof (100 meters / 200 meters):

100 meters waterproof: The watch can withstand water pressure of about 100 meters depth, suitable for swimming and snorkeling, among other water sports.

200 meters waterproof: Compared to 100 meters waterproof, a 200 meters waterproof watch is suitable for deeper underwater activities, such as surfing and deep-sea diving.

It’s important to note that these waterproof ratings are determined based on standard testing conditions and do not imply that you can use the watch at that depth for extended periods.

Maintenance Guide for Waterproof Watches:

The waterproof performance of a watch may gradually decrease over time due to usage, external conditions (such as temperature, humidity, etc.), and mechanical wear. In addition to design factors, improper usage is the main cause of water ingress in watches.

When using a waterproof watch, it is important to observe the following points to ensure its performance and durability:

● Avoid Pressing Operations

● Avoid Rapid Temperature Changes

● Regular Maintenance Checks

● Avoid Contact with Chemicals

● Avoid Impact

● Avoid Prolonged Underwater Use

Overall, while waterproof watches offer a certain level of water resistance, they still require careful usage and regular inspection and maintenance to ensure their performance and durability.
