How can I care for my Valjoux 7750b1/7750a based watch?
To avoid doing damage to your 7750 movement, please do not set the date when the watch is between 10:00 and 3:00. If you need to set the date, please adjust the time temporarily outside of the 10-3 range, set the date, and then re-set the time. Setting the date while the watch is between 10:00 and 3:00 will damage the gears of the watch. Please note that the Swiss 7750b movement uses a pusher button on the side of the case to set the date, and the date on these models can be set at any time. When you first receive the watch, please give it 40-50 winds to get the power-reserve back up to optimal conditions.
