Smartwatches with classic clasp

Classic buckle

— clasp resembling a belt buckle; it was originally used in traditional wristwatches, but nowadays it has also become widespread in smartwatches. One half of such a clasp has a U-shaped or similar frame with a special pin, and the other half has a row of holes. When fastening, the second half is threaded through the frame, and the pin is fixed in one of the holes. At the same time, by choosing a particular hole, you can adjust the size of the strap. The advantages of the buckle are reliability, neat appearance and compatibility with many strap materials (except metal bracelets). Such a clasp may be the only available option, or it may be complemented by another bracelet — with a clip or magnet (see the relevant paragraphs).
