The End-of-Life (EOL) indicator appears on selected quartz movements when the battery is nearly depleted. The seconds hand pauses and then jumps forward, often in four-second steps, while the watch continues to keep time. The watch is not necessarily faulty, but the battery should be replaced promptly by a professional watchmaker or an authorized service centre.

Yes, quartz watches are known for "high accuracy." Because the quartz crystal vibrates at such a stable and high frequency, they are typically much more accurate than mechanical watches, often varying by only a few seconds per month.

This is the End-of-Life (EOL) indicator used in selected quartz movements. The watch continues to keep time, but the battery is nearing depletion. Have the battery replaced promptly by a professional watchmaker or an authorized service centre.

A watch may be labelled “Swiss Made” only if it meets Swiss legal requirements. Its movement must be Swiss, the movement must be cased in Switzerland, the completed watch must be inspected in Switzerland, and at least 60% of the manufacturing costs of the watch as a whole must be generated in Switzerland. Jowissa watches are assembled and quality-controlled in Bettlach, Switzerland.

The name Jowissa is derived from the name of company founder Josef Wyss. He founded the business in Bettlach, Switzerland, in 1951, and Jowissa has operated continuously since then.

The expected battery life is 2 to 4 years depending on external factors like heat and cold. Jowissa uses standard silver oxide battery cells in combination with high quality and low energy consuming Swiss quartz movements.

Yes. Many Jowissa watches use interchangeable bands, and selected bands have a quick-release system that can be changed without tools. Other straps or bracelets may require a spring-bar tool or a watchmaker. Before ordering, check the band width and attachment type for your watch.

A Jowissa watch is tested for water resistance from 3 to 30 ATM, depending on the collection.
3 ATM: Watches tested to 3 ATM should not be worn while bathing or showering. They are built to withstand light rain, perspiration and brief contact with water.
5 ATM: Watches tested to 5 ATM are designed to withstand rain, perspiration and brief contact with water. They are not intended for swimming or diving.
10 ATM: Suitable for swimming and other surface water activities. Not intended for diving.
20 ATM: Suitable for swimming, water sports and recreational diving.
Always follow the water-resistance rating and product specifications for your exact model.
