Large watches with a diameter of over 44 mm are no longer rarities. The longer a battery can be used, the lower the number is that end up harming the environment. Rotation intervals are very helpful when the winder is battery operated. Furthermore, a watch winder requires more energy if it never pauses. While an automatic watch will not be damaged if it rotates more than 1,000 times in 24 hours, it is subject to additional wear.
Most movements require around 1,000 rotations a day before they're fully wound. Watch winders with rotation intervals switch between rotating and pausing. The rotor in the Valjoux 7750, the most well-known chronograph caliber in the world, is only wound in one direction.
Motors with a ball-bearing construction save energy, last longer, and are quieter.Ī good watch winder turns in multiple directions, as not every automatic caliber can be wound in both directions. High-quality watch winders feature motors with a ball-bearing construction, which differ from belt-driven motors. If you're interested in buying a watch winder, you should pay careful attention to the type of motor, as it plays a deciding role in the device's lifespan and noise level.
