Abstract: In embodiments of wearable device heart monitor systems, a wearable device has electrical contacts integrated in a housing base of the wearable device as electrodes designed to contact skin of a user while wearing the wearable device. A housing bezel of the wearable device designed as an additional point of contact on the wearable device. The wearable device includes an electromyography (EMG) system to receive electrical signals from at least two of the electrodes and detect muscular movement of the user. Further, the wearable device includes an electrocardiogram (ECG) system to receive and combine the electrical signals from the electrodes when the user touch contacts the housing bezel while wearing the wearable device to complete an ECG loop between the electrodes and the housing bezel for a heart rate reading of the user.

Abstract: A device includes a case having a case sidewall defining a circular receiver having a receiving opening and a central axis. A device body, which is waterproof in one or more applications, includes a sidewall defining a receiving aperture. A crown stem includes a push button disposed within a duct of a threaded bushing and one or more O-rings disposed about the actuation stem to allow translation of the actuation stem in the duct while preventing liquids from passing through the duct. The crown stem inserts through the aperture in the case so that the threaded bushing can hermetically seal the receiving aperture when the device body is inserted into the circular receiver to prevent the liquids from entering the receiving aperture.

Abstract: A device includes a case comprising a case sidewall defining a circular receiver having a receiving opening and a central axis. An inner wall of the case defines one or more engagement members. A device body includes a sidewall defining a receiving aperture. The device body inserts into the circular receiver along the central axis at a first rotational alignment. A bezel is coupled to the device body, and couples to the case at the receiving opening. The bezel includes an annular engagement ring defining one or more complementary engagement features to engage the one or more engagement members. A crown stem serves as an axial retention device to retain the device body in the second rotational alignment.
