According to etiquette, a woman should wear her watch on the left wrist if she is right-handed. This traditional rule places the watch on the non-dominant hand to prevent damage and scratches from daily tasks. However, modern fashion is flexible: many women choose the wrist that best complements their other jewelry. If you wear a heavy bracelet on your left hand, it is perfectly stylish and practical to wear your watch on the right wrist to balance your look and avoid scratching the timepiece.

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 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.
