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.

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.

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 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 ideal watch size depends on your wrist circumference and personal style. As a general rule, for wrists under 15cm, case diameters between 20mm and 30mm look most balanced. For wrists between 15cm and 17cm, sizes from 30mm to 35mm are ideal. For larger wrists, cases 35mm and above provide a bold look. Jowissa offers a variety of sizes, ranging from our petite 20mm mini models to our larger 45mm options for men.

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.

This is a deliberate feature called the End-of-Life (EOL) indicator, found in high-quality Swiss quartz movements. It signals that the battery is nearing the end of its life and needs to be replaced soon. Your watch will continue to keep accurate time, but you should visit a professional watchmaker to have the battery changed within the next few weeks.

This rule applies to both quartz and automatic watches. You should avoid manually changing the date during these hours (the "danger zone") because the watch's internal gears are already engaging to advance the date automatically. Forcing a manual change while these gears are locked can break the delicate teeth of the movement. Pro tip: To be safe, always pull the crown out and move the hands to 6:30 before setting the date, then reset the time to the correct hour.

Physical Vapour Deposition (PVD) is a process where an exceptionally pure, solid coating material is used to generate an ionized metal vapour which forms a coating mixture with inert gases.

Through condensation, a thin layer is deposited onto the surface of the watch. The PVD process is carried out under a forced vacuum in a coating chamber. This procedure is one of the most modern and ecologically sustainable coating technologies. PVD coatings are highly adhesive, hard and abrasion-resistant. They are extremely smooth and particularly suited to coating watch parts. These coatings can be single-layer, multi-layer or can be applied in graduated layers. The layer thickness ranges from 1 to 5 microns, although in some cases, just 0.5 microns or 15 microns and more can be applied.

Depending on the initial material and the inert gas employed, a wide range of PVD coatings can be applied. Essentially, these fall into four main groups: nitrides, carbides, oxides and carbons (Diamond like carbon).

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.
