Summer is for water activities: You must understand your watch's water resistance rating!

  Summer has just begun, and we have well and truly entered the season. The weather in the south is particularly sweltering; besides cooling down with air conditioning indoors, swimming and playing in the water outdoors have become the best ways to beat the heat. At the same time, we must understand the water resistance rating of our watches so we can happily wear them in the water. Below, we will teach everyone how to clearly understandDiving watchwater resistance ratings.

　　Generally, you can see water resistance markings on the back or dial of a watch, but most are not marked in metres; they are usually marked in Bar. Bar represents the intensity of water pressure the watch can withstand, calculated based on the pressure at a certain depth, which is much more rigorous than a depth rating in metres.

　　What is the difference between 30-metre water resistance and 50-metre water resistance?

　　There is essentially no difference between 30-metre and 50-metre water resistance, as both fall under the splash-proof category. Simply put, they can handle washing and rain, but not showering. If you must distinguish between the two, it comes down to the volume of water. 30-metre water resistance only meets basic hand-washing needs, while 50-metre is slightly more secure against accidental exposure.

　　What are the uses for 100-metre, 200-metre, and 500-metre water resistance?

　　Can you swim with 100-metre water resistance? Actually, it is not determined by the water resistance rating, but by the style of the crown. If the crown is a screw-down type, you can swim, even if it does not reach a 100-metre rating. For example,Replica IWC watchesmany models are only marked with 60-metre water resistance, but in reality, they can be worn while swimming. If it is not a screw-down crown, then it is a bit unreliable.

　　Watches with 200-metre water resistance all use screw-down crowns, which is when they truly enter the diving watch category. Therefore, we can understand it this way: 200-metre is for swimming, 300-metre is for snorkelling, and 500-metre is for deep diving. As for anything above 500 metres, it is not only for deep diving but also for showing off. Because water resistance above 500 metres has no practical significance for the user; the only thing it reflects is the watch manufacturer's dedication to water-resistance technology.
