Abstract: To a branch (40) of a metal bracelet applicable to watches is fixed a frame (12) having a movable catch plate (20) and to which is hingedly connected an overturnable plate (14) having an end hook (34). Connected to the opposite branch of the bracelet is a forked member (16) having a tie bar (30) which fits into semicircular seats (26) formed in the frame (12) upon closure of the device. In another embodiment, the closing device includes two arched sheets (52) and (54), in sheet (54) a chamber (66) is formed in which slides a catch plate (76) the front end of which is coupled below the hook (52') formed at one end of sheet (52) upon closure of the device.

Abstract: The band consists of a plurality of links (20), (22) formed by bringing together four turns (12a), (12b), (12c) and (12d) constrained together by means of pins or equivalent elements inserted in the substantially cylindrical seat which said turns create by partial reciprocal penetration. At least one of said turns and preferably the fourth turn of each link is provided on one side with internal threading into which screws the end (18') of the screw (18) constituting the means of connection between two links (20), (22) and is arranged between the side blocks (30). An alternative form of execution provides that to the branches (42) and/or (44) of the band (40) are connected one or more segments (52) made of metal fabric similarly to the band itself. Said connection is provided by pins inserted in the tubes (54) formed by tube sections (54'), (54"), (54"').

Abstract: The closing device consists of a frame (12) and opposed arms (14) with hook (18) designed to be inserted in the central bolt (20). In the latter, which is bounded below by the base (24) and above by the crosspiece (30) there is arranged in a sliding manner the plate (28) with openings (32), (36) and (34). The latter receives the spring (42) while in the openings (32) and (36) are engaged the hooks (18) of the arms (14).The end (28') of the plate (28) is drawn manually outward and brings about simultaneous unhooking of the arms (14) to which are constrained the band branches.Additional forms of embodiment call for the use of a bolt (60) with pushbutton (68) for simultaneous unhooking of the arms (54) and a bolt (90) with pushbutton (98) which moves opposed shaped plates (94), (94') which constrain the arms (84).
