Time and Space Universal Watch

Ye Yu: 'Travel through the first world and add a second watch world' Ye Yu picked up a strange-looking watch when he was off work. This watch has no strap and no time display, but it can be seen that it is a watch. The watch Ye Yu picked up is not like any ordinary watch. The watch only has three options, 'Confirm, Modify, and Charge.' What can this watch bring to Ye Yu? This novel and its characters are purely fictitious.
