The present utility model discloses a watch frame, which is provided with a groove for mounting a dial, and the inner wall of the groove is provided with an elastic clip strip for elastically clamping the dial. The beneficial affected areas are below: An elastic clip strip is set in the groove of the watch frame, due to flexibility of the elastic clip strip it is compressed when the dial is installed so that the dial can be easily mounted into the watch frame. The dial can be clamped in the watch frame firmly. When disassembling, the dial can be removed from the watch frame by pressing the dial in downwards motion which saves time and labor and does not need any auxiliary tools.

A watch can include a mechanical watch, the mechanical watch having a mechanical watch housing, and a mechanical watch face retained at least partially within the mechanical watch housing; a first watch band portion; and a second watch band portion. The watch can further include a circuit board associated with a controller, the circuit board and controller being at least partially retained by a clasp. The circuit board and the controller can be electronically and operatively independent from the mechanical watch.

A smart watch and a method for measuring a pulse information are provided in the present disclosure. The smart watch includes a dial, a watchband, a blood vessel information collecting apparatus, and a processing apparatus. The watchband is connected with the dial. The blood vessel information collecting apparatus is disposed in the watchband and is configured to collect a blood vessel information from an inner side of a wrist of a user. The processing apparatus is connected with the blood vessel information collecting apparatus and is configured to receive and process the blood vessel information to obtain the pulse information of the user.

A bracelet or strap for a watch case including a first arm inside which is housed a first printed circuit portion and a second arm, where the first arm is extended by a median part arranged to be situated underneath the watch case and which includes a second printed circuit portion connected to the first printed circuit portion by electrical connection, where the first printed circuit portion carries at least one electrical energy source and a microcontroller for powering and controlling a pressure sensor, where the median part is covered by an insert arranged to act as a seat for the watch case, where a housing, inside which the pressure sensor is arranged, is provided in the insert and communicates with the exterior to allow the pressure sensor to be placed in contact with a surrounding medium, and the pressure sensor is mounted on the second printed circuit portion with the insertion of a sealing gasket between the housing and the second printed circuit portion.

A wearable device includes: a touch screen; an acceleration sensor configured to generate an acceleration signal; an optical sensor using a light source and configured to generate a touch interrupt signal; and a control unit configured to detect a wearing state of the wearable device, the wearing state of the wearable device including a not-wearing state for the wearable device, a wrist wearing state, and a hand gripping state on the basis of the acceleration signal and the touch interrupt signal, and to execute a function corresponding to the wearing state of the wearable device.

Embodiments of a watch can include a watch having an analog watch face, a first watch band portion, and a second watch band portion, where the watch can include a digital clasp having a digital display and a circuit board associated with a controller.

An insert for a watch that enables the wrist watch to be positioned on the forearm of a person such that the main body and face of the wrist watch is disposed adjacent an inner side or edge of the forearm in a convenient line of sight for the person wearing the wrist watch. The insert includes a web and a pair of flanges extending from the web. The insert is designed to be attached to the watch such that the web and flanges form an interface between the wrist watch and a person's forearm for securely stationing the main body and face of the watch on the inner side or edge of the forearm.

Embodiments of a watch can include a watch having an analog watch face, a first watch band portion, a second watch band portion and an analog watch face. The watch can include a digital clasp having a digital display and a circuit board associated with a controller.

A portable electronic device is proposed, configured for positioning on a user's wrist, for performing an electrocardiogram. The device includes exactly two ECG electrodes, the potential being imposed on one of the two ECG electrodes. The two electrodes consist of a first ECG electrode at the case back and configured to be in contact with the skin of the wrist, and a second ECG electrode.
