LeWy 15 Swiss Men's Watch J7.109.L

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.

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.

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.

In modern parlance, the word 'chronograph' is used to refer to a timepiece which, along with telling the time, serves to measure short times using at least one additional hand. The latter can be started, stopped and reset to zero without disturbing the smooth running of the movement, by means of a control system, generally composed of pushbuttons. If the chronograph function is not associated with a watch as such, the instrument is simply referred to as a timer (or sometimes a stopwatch).

Technically speaking, the chronograph mechanism can be either built into the watch movement, or mounted on the latter in the form of an add-on module. A significant step was taken in 1816, when Parisian horologist Louis Moinet developed what he called a compteur de tierces.
