Therefore, regular wear does not require manual winding. Only when the wearer's activity level is insufficient to wind the mainspring might manual adjustment be needed. This is a common misunderstanding among those unfamiliar with mechanical watches, who often think there is a problem with the watch.Additionally, to prevent moisture from entering the case and to maintain the watch's waterproof performance, ensure that the crown is securely locked after adjusting the watch. It's also important to note that waterproof watches are only waterproof for everyday use; they may not withstand hot water.
