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.

It works through a circuit: a battery sends electricity to a quartz crystal, causing it to oscillate (vibrate) 32,768 times per second. A microchip detects these vibrations and converts them into regular electric pulses (one per second). These pulses drive a stepping motor, which turns the gears and moves the watch hands.

A quartz watch is a timepiece powered by a battery rather than a wound spring. The "quartz movement" refers to the internal engine of the watch, which uses a tiny crystal of quartz mineral to regulate time. This crystal vibrates at a very precise frequency when electricity is passed through it, ensuring high accuracy.

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.

Measure your wrist circumference, then compare the case diameter and strap length in the product specifications. Case shape, lug-to-lug length, thickness and personal style also affect how a watch wears, so diameter alone is only a guide. A smaller case usually looks discreet; a larger case makes a stronger statement. Choose the proportions that feel comfortable and suit your style.

On many watches, the date-changing mechanism begins to engage around midnight. Using the quick-set date while it is engaged can damage the movement. The exact restricted period varies by movement, so follow the instructions for your watch. If you are unsure, move the hands to about 6:30 before setting the date, then set the correct time.

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.

Traditionally, a man wears his watch on the left wrist. This custom originated because the majority of people are right-handed, and wearing a watch on the non-dominant hand protects the timepiece from damage and keeps the dominant hand free for writing or working. However, the modern rule is practical: wear your watch on the wrist opposite your dominant hand. Therefore, if you are left-handed, it is perfectly acceptable to wear your watch on the right wrist.

Luminous hands on a watch refer to the hands (hour and minute, and sometimes the second hand) that have been treated with a phosphorescent material. This material absorbs light from various sources, such as sunlight or artificial light, and then emits that light over a period of time, allowing the wearer to read the time in low-light or dark conditions.

At Jowissa, we incorporate luminous hands into select models to enhance their practicality and legibility. This feature ensures that the time can be easily discerned, even when visibility is limited. The application of luminous material is carefully considered in our designs to complement the overall aesthetic of each timepiece while providing functional benefit to the wearer.

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.

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.

No. Watches tested to 5 ATM are designed to withstand rain, perspiration and brief contact with water. They are not intended for swimming or diving. For water activities, choose a model with a rating specifically suited to that use and follow its product specifications.

A tachymeter is a scale used with a chronograph to calculate average speed over a known distance. Start the chronograph at the beginning of one kilometre or one mile and stop it at the end. The central chronograph seconds hand points to the average speed in units per hour. For example, 30 seconds over one kilometre corresponds to 120 km/h. The scale only works for times within its displayed range.
