Yes, these terms are often confused but mean different things. A Chronograph is a watch with a built-in stopwatch function (buttons to start, stop, and reset). A Chronometer is a specific certification given to a high-precision watch movement (usually mechanical) that has passed rigorous accuracy tests by COSC (Official Swiss Chronometer Testing Institute). A watch can be both, but "Chronograph" refers to the function, while "Chronometer" refers to the accuracy rating.

While possible, it is generally not recommended for battery-powered quartz watches. Leaving the chronograph function running continuously drains the battery significantly faster than standard timekeeping. To preserve battery life, we suggest stopping and resetting the chronograph hands to zero when you are not actively timing an event.

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.

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.

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.

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.
