Last night I told you in what conditions it is Apple Watch water resistant, the Apple company stating that the product can be used while washing our hands, when it's raining outside or when we exercise and sweat. Apple also mentioned the fact that Apple Watch it is certified under the IPX7 waterproof standard, and according to it we can use the new Apple smartwatch underwater. More precisely, we can use the Apple Watch under water for 30 minutes if the depth does not exceed 1 meter.
IPX7 is the grade at which a phone continues to function and no water gets inside when it is immersed in a tank filled with still tap water to a depth of 1m at room temperature and left at the bottom of the tank for approximately 30 minutes.
Using the Apple Watch underwater at a depth of 1 meter for 30 minutes should keep the Apple Watch functional even after removing it from the water, so you should not worry. In these conditions, using Apple Watch in the shower it shouldn't be a problem, but Apple has avoided mentioning this for now. Even so, since it says that the Apple Watch is certified with the IPX7 standard, theoretically the watch should be usable even in the shower, if you want to use it there.
