You can even wear it while showering, but only if the watch is new or has recently been resealed. This is because the water resistant seal on the watch may weaken with time, especially if it is dropped. If this happens, you should get out of the shower immediately and try again later. Showering with any kind of jewelry in place is not recommended because the movement of your body while bathing could cause the jewelry to rub against your skin, irritating it and possibly causing pain or discomfort. Even if you don't feel anything at first, over time this could lead to skin infections or scars. However, if you have old jewelry that is no longer safe to be around water, then now is the time to get rid of it. Preferably, you shouldn't wear any kind of jewelry when taking a bath or shower. The American Cancer Society recommends that you not wear jewelry while taking a bath or shower. The reason for this is so that you don't rinse any unwanted chemicals into your bloodstream through wet jewelry. Also, if you happen to get scalded by hot water, you won't be able to put up a fight against metal poisoning.
