Deployant clasp watches

Deployant clasp

— folding clasp with a latch, a kind of "latch" (many clips open and close with a characteristic click).

The most popular design of such a clasp is based on two plates that fit snugly together in the closed position and unfold like a book spread when opened. However, there are other types of clips — for example, "butterfly": in such designs, two movable plates are used, attached to the base with the help of rotary axes and opened like butterfly wings (hence the name).

Anyway, clip-on earrings are almost the only available option for bracelets made of steel and other hard materials (with a few exceptions — see "classic (with buckle)"). However, in addition to this, this type of clasp can also be found in soft straps — primarily leather ones. This design is typical mainly for fairly expensive watches; for its advantages over traditional buckles, see also "classic (with buckle)".
