A quartz watch works by using a battery to make a quartz crystal vibrate. The consistent
vibrations are electronically counted and converted into second pulses, which display the time
precisely and reliably.

Quartz watches are very reliable and have a time deviation of only about ±15 to 20 seconds
per month.

Depending on the model and additional functions (e.g., date, chronograph), the battery life
is typically 2 to 3 years.

Often, the second hand starts to jump in larger increments (e.g., every 2–4 seconds). This
indicates a weak battery and the need for a replacement. Please refer to the respective manual.

We recommend having the battery replaced by a qualified professional. This ensures that the
case is opened correctly and the watch's water resistance is checked.

Most quartz models are water-resistant (3 to 10 ATM). Please refer to the information on the
case back and the respective model description.

Clean the case regularly with a soft cloth and avoid extreme temperatures, strong magnetic
fields, and chemicals. This will ensure your watch remains functional for a long time.

Quartz watches are designed for everyday use. Nevertheless, strong impacts and shocks or
submersion in water (for non-waterproof models) should be avoided.

Kienzle1822 stands for German watchmaking tradition since 1822. Our quartz watches combine
high precision, modern design and durable materials to create an ideal companion for everyday
life and business.
