The reason why Rolex watches are not allowed: mechanical watches do not need batteries, but they also need energy supply. Automatic mechanical watch mainly converts the energy generated by human arm movement into mechanical energy, thus completing the operation of the whole machine. Insufficient winding of a watch will lead to the watch not moving accurately or even not moving. If this problem occurs, you can start winding again according to the instructions of the watch, or go to the Rolex Watch after-sales service center to ask the staff for help. Precautions for adjusting Rolex watches: Please note before preparing to adjust the time: If it is a watch with a spiral crown, do not pull it out by force. Please turn counterclockwise to open the locked crown. After adjusting the time, turn it clockwise and push it into the lock to avoid water. Secondly, pay attention to the restricted area of the mechanical watch movement 265438+ 0 pm to 4 am. During this period, it is not advisable to adjust the week and calendar, otherwise it will damage the movement.
