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.

The moon-phase indication is a device serving to visualize on the watch dial the various appearances adopted by the Earth's satellite in the course of a lunar cycle: it may be waxing, full, waning or entirely hidden by the shadow of the Earth - and thus referred to as a new moon.

These different phases are traditionally represented by a mobile disk bearing two diametrically opposite depictions of the Moon alternately appearing through an aperture. The latter is cut out so as to provide a visual simulation of the Moon's waning and waxing episodes. As soon as the first interpretation vanishes, the second instantly comes on the scene. Moon phases may also be indicated by means of a hand pointing to various symbols, or by a three-dimensional sphere spinning on its axis, and of which one half is light-colored while the other is dark.

The mechanical difficulty of moon phases lies in the unusual interval between two full moons. By the 20th century, this complication had become essentially a romantic feature.

A watch can only be labeled "Swiss Made" if it meets strict legal standards set by the Swiss government. It requires that the movement is Swiss, the movement is cased up in Switzerland, and at least 60% of the production costs of a watch taken as a whole must from Switzerland. At Jowissa, we proudly assemble our watches by hand in Bettlach, Switzerland, ensuring every timepiece meets these high standards of quality and precision.

The name Jowissa is a combination of the surname and lastname of the company founder Josef Wyss. He founded Jowissa in the village of Bettlach, Switzerland in 1951. Jowissa has been active and in business without interruption since then.

A Jowissa watch is tested for 3 to 20 ATM water resistance depending on the collection.
3 ATM: Watches tested for 3 ATM should not be worn when bathing or showering. They are build to withstand light rain, sweat and brief water contact.
5 ATM: Watches tested for 5 ATM are made to withstand rain, sweat and short swims.
10 ATM: Short dives, swim and other water sports are ok
20 ATM: Deep Dives, swims and other water sports are ok.
