How is the water resistance of Jiusid watches?

　　The niche Swiss brand Jiusi has won favour with many budget-conscious consumers through its exquisite craftsmanship and elegant design. Therefore, "are Jiusi watches water resistant?" is a concern for many Jiusi owners. Allow me to introduce it to you below!

　　1. Scratch-resistant sapphire crystal watch glass, with anti-reflective treatment on the inner side.

　　2. Screw-down crown with double security gaskets for dust- and water-resistance effects (on selected models).

　　3. Hands, hour markers and bezel scale feature a luminescent effect for clear legibility underwater (on selected models).

　　Can watch water resistance be trusted?

　　How did a timepiece with a water resistance depth of one hundred metres let water in at eighty metres?

　　Speaking of depth, if you are not a professional diving enthusiast, you probably do not know how many metres you have descended. For those of you mostly just splashing around in shallow water areas, a basic waterproof watch with a rating of fifty or sixty metres is enough for your use. Of course, because of this, you have no way of knowing the accuracy of the value.

　　In fact, in watch testing and measurement, the waterproof depth expressed in metres is merely a theoretical value. Waterproof depth refers to the water resistance when both the watch and water are completely stationary. This stationary condition does not exist in the real world for swimmers or divers. So when you put on your 100-metre deep-water resistant watch, make sure you do not get carried away and swim down to a depth of 100 metres.

　　Friends around me often ask questions like this. The paradox of complete water resistance versus water ingress frequently occurs. According to guidelines issued by the US Federal Trade Commission, watch sellers must not label their watches as completely water-resistant.

　　Meanwhile, certain timepieces such as the Rolex Submariner and Blancpain Fifty Fathoms are deep-diving watches manufactured specifically for deep diving. Although their water resistance has reached an exceptional level, even claiming they can stay in the deep sea for a period without issue, they still cannot be termed completely water-resistant.

　　You would be far too easily swayed to dismiss the idea of buying a water-resistant watch just by seeing the two points above. The primary function of a good water-resistant watch is water resistance, and consumers can fully consider what kind of water-resistant watch to buy based on their usual lifestyle and wearing habits, whether it is basic daily water resistance, swimming water resistance, or deep-diving water-resistant watches. Although the standard values cannot be trusted implicitly, they also indicate a range of instructions for use, so there is no need to worry too much when purchasing.
