- Our quartz movement watches get their power from a battery. Because they are driven and regulated by battery power, quartz movements tend to be highly accurate when compared to other types of watch movements. Depending on the features, quartz watches will need a new battery every 2-3 years.
- Automatic movements use energy from the motion of your wrist. Every time the watch moves, a weighted rotor attached to the back of the movement spins, automatically winding the mainspring which drives the internal gears. This is why you may hear someone refer to an automatic movement as a self-winding movement. Since the mainspring exerts a variance in driving force depending on how tightly wound it is, the accuracy of an automatic watch fluctuates depending on usage. However because they are mechanically driven, you will never need to replace a battery on an automatic watch. Although we do recommend getting your automatic watch serviced by a professional every 3 to 5 years to maintain proper function.
- If you do not wear your automatic watch often you may want to invest in a watch winder. These are relatively inexpensive and will keep you from having to reset your watch when you do decide to wear it after a break.
