Frequenty Asked Questions

What should I avoid in order to keep my watch in perfect order?

Avoid exposing your watch to strong magnetic fields, extreme temperatures, or shocks, as these can affect its precision. Keep it away from chemicals, perfumes, and solvents that may damage the case, strap, or seals. A little care ensures lasting performance and appearance.

What precautions can I take before using my watch in water?

Always make sure the crown is fully pushed in or screwed down before exposure to water. Avoid pressing any buttons underwater, and rinse the watch gently with fresh water after contact with salt or chlorinated water. Regularly check the water resistance if you wear your watch often near water.

How should I care for my watch when I’m not wearing it?

Store your watch in a cool, dry place away from direct sunlight and humidity. For automatic watches, a watch winder helps maintain movement and lubrication. Keep it in its original box or a soft case to protect it from dust and scratches.

What is the best way to clean my watch?

Clean your watch gently with a soft, lint-free cloth to remove dust and fingerprints. For metal bracelets, use a soft brush with mild soapy water, then dry carefully with a clean cloth. Avoid immersing leather straps in water.

What is an automatic movement?

An automatic movement is powered by the motion of your wrist, eliminating the need for a battery. The rotor inside the movement winds the mainspring as you move, storing energy to keep the watch running smoothly. Regular wear keeps the mechanism fully charged.

What is a quartz movement?

A quartz movement is powered by a battery and regulated by a vibrating quartz crystal, ensuring high accuracy and minimal maintenance. Unlike mechanical movements, it requires no winding. The battery typically lasts between two and three years before replacement is needed.

What is a power reserve?

The power reserve indicates how long your automatic watch will continue running when it is not being worn. It represents the stored energy in the mainspring and typically ranges between 36 and 48 hours for most Jacob Zech timepieces.

How do I restore full power to my automatic watch?

If your watch has stopped, you can restore full power by manually winding the crown about 20–30 times. Wearing the watch for several hours will also recharge the mainspring through the natural motion of your wrist.
