Put simply, an automatic watch does not require a battery in order to function. Whereas, a quartz watch requires a battery. In more technical terms, a mechanical watch operates using power obtained from a mainspring. The mainspring receives the energy and gets wound with the motion of the wrist thanks to a weighted rotor.

Yes. However, when the watch is fully stopped, manually turn the crown clockwise to wind up the mainspring and as soon as the watch starts, put it on your wrist so the remainder of energy comes from the natural movement of the wrist. In order to maintain the accuracy of the watch, we recommend wearing it at least 8 hours a day. The more you wear your watch, the less a manual intervention is needed.

Step1: Make sure the hour and minute hands are not within 3 hours of midnight in order to not interfere with the automatic date change mechanism. To be safe, move them away by setting the time at 6:30.

Step2: With crown out to position 1, set the date to yesterday's date.

Step3: Wait until the second hand reaches 12 and then pull the crown out to the last position. The second hand will stop thanks to the hacking mechanism. Then rotate the crown counter-clockwise until the date shows the current date.

Step4: At this stage, the time is approximately 12 AM. Keep rotating the crown counter-clockwise to reach the correct time paying attention to AM and PM.

Tip: You can use an accurate time source such as time.gov to set your time.
