The invention discloses a smart watch, which comprises: a dial (10), a first and a second straps (20,24), connected respectively to both sides of the dial (10); wherein a first and a second displays (12,13) are disposed respectively on a front and a back of the shell body (11) of the dial (10), the first and second straps (20,24) are disposed with a plurality of clasps (21) and clasp holes (22) correspondingly, and the first and second displays (12,13) can have the same or different shapes and sizes, depending on whether the watch is worn on front or back, so that when worn on different side, different display is viewed to achieve complex application. Designing different appearances for the front and back of smart watch satisfies various esthetics, and manufacturing the first and second displays (12,13) monolithically simplifies the control circuit to improve smart watch quality.

The invention discloses a smart watch, which comprises: a dial (10), a first and a second strap (20, 24), connected respectively to both sides of the dial (10), a main display (12) disposed on a front of the dial (10), a first secondary display (13) disposed on the end of the first strap (20) connected to the dial (10), and a second secondary display (14) disposed on the end of the second strap (24) and connected to the dial (10) to increase the display area of the smart watch to achieve complex human machine interaction to satisfy various demands for display by the users. By using monolithic manufacturing method, the invention achieves reducing the number of control circuit and cost. The present invention provides a multiple numerical operation method for smart watch is easy to operate and can enhance user experience.

A portable object includes a case having a middle, a bracelet, and an attachment system for removably securing each end of the bracelet to the middle. The middle includes two longitudinal cavities to form a slide bar. Each end of the bracelet includes a fastening head that cooperates, by sliding, with one of the longitudinal cavities to form the attachment system. The fastening head includes an end flange made of a viscoelastic material. The attachment system includes a viscoelastic fitting for locking axial movement of the fastening head inside the longitudinal cavity by the viscoelastic response of the end flange. The viscoelastic fitting is formed by cooperation of a rigid locking protrusion in each longitudinal cavity to deform the end flange upon insertion of the bracelet. The locking protrusion fits inside a recess made in the end flange to lock the axial movement of the fastening head.

A wearable object including a middle of a case, a bracelet, and a fastening system for removably securing the bracelet to the middle, the middle including two longitudinal cavities configured to form a slide-bar and receive a hooking head of the bracelet of complementary shape and configured to cooperate by sliding. The fastening system includes elastic casing elements to bolt the axial movement of the hooking head inside the longitudinal cavity, the elastic casing elements including: a rigid bolting protrusion, arranged on an inner wall of each of the longitudinal cavities, cooperating with; two obstacles arranged in the vicinity of an elastic portion of the hooking heads, the obstacles delimiting an inter-obstacle space designed to receive the bolting protrusion and form locking elements of the bolting protrusion; the elastic casing elements being configured to elastically distort the elastic portion of the hooking head during the insertion of the bracelet.

A connection structure includes: a connection pin that includes a first part and a second part between which a step is formed and that connects a first target and a second target by being inserted in an insertion hole; and a pin locker movable in a moving direction in a recess formed in either the first or second target. The pin locker has a pin engaging part that engages with the step of the connection pin and a pin insertion part. One of the recess and the pin locker has a first abutting part, and another has a first abutted part. When the pin locker is at a specific position and the first abutting part abuts the first abutted part, at least either an orientation or a position of the pin insertion part is limited such that the second part is allowed to pass through the pin insertion part.
