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.
