Why 30-Meter Water-Resistant Watches Aren’t Suitable for Diving—and Which Models Can Truly Handle Immersion?

Why can’t 30-meter water resistance watches be used for diving? Which watches can really be used for diving?
1、Why can't a 30 meter waterproof watch dive?
In fact, this 30 meters is not in real life, 30 meters means 3ATM, that is, three atmospheres of pressure, in an ideal environment, in fact, some people will write life waterproof, the same meaning can only stop the daily hand washing, raindrops and so on, can not resist immersion or direct rinsing. So if you want to buy a watch, you should carefully understand the water resistance of this watch.

The watch is water resistant.
The waterproof of the watch generally includes:30 meters, 50 meters, 100 meters, 120 meters, 200 meters, 220 meters, 300 meters, 500 meters, 1000 meters, 1200 meters and so on. Deeper still, watches after 1000 meters are professional diving watches.
If you just swim, it is recommended to buy 100 meters, many advertisements say that 50 meters can be swum, but there are a lot of watch friends who have tried it reported that this depth watch will be in the water when swimming, so 100 meters is a little bit more reliable, why try to buy a watch with high waterproof ability? Because waterproof actually has the role of waterproof rubber ring, just like the pressure cooker rubber ring, can seal the high pressure steam, but the pressure cooker may need to replace the rubber ring, our watch waterproof ring will also aging, usually some batteries or dismantling maintenance will accelerate the aging of the watch rubber ring, of course, the waterproof ability is also gradually decline. Therefore, watches with high waterproof coefficient are more durable.

2. Which watches can really dive?
What is a dive watch? Marked 100m, 200m and 300m. these watches are usually used for professional diving. The markings on the watch are real data. Marked 100m, you can dive in water depths up to 100 meters. This type of watch can be used normally in everyday life, such as washing hands, getting wet (cold water), rinsing and swimming. By analogy, 200m and 300m can be used in the corresponding water depth range. We must note that the water mentioned here is cold, not warm, let alone hot. So no matter if your watch is a professional 300m waterproof watch, you should still try not to use it in warm or hot water, not to mention hot springs or saunas.
