A watch can include a watch band having a first strap segment, a second strap segment, a nest portion secured between the first strap segment and the second strap segment, and an opening extending through the nest portion. The watch can further include a housing releasably mountable to the nest portion, and a sensor disposed within the housing and configured to align with the opening when the housing is mounted to the nest portion.

The present disclosure provides an electronic apparatus and a wearable apparatus. The electronic apparatus may include a housing assembly and an electronic component. The housing assembly is configured to connect with a connector, and includes a housing and an engaging member. The housing defines a mounting groove. The engaging member is arranged in the mounting groove and capable of moving relative to the housing to engage with the connector or disengage the connector. The electronic component is disposed in the housing. The housing defines a sink. The housing assembly further includes a baffle mounted in the sink, and the baffle defines a through hole being configured to let the connector pass therethrough.

A carbon fiber watch case includes a main body structure and a conductive structure. The main body structure has an inner surface and an outer surface. The conductive structure has a first contact on the inner surface and a second contact on the outer surface to electrically connect the inner surface and the outer surface of the carbon fiber watch case. The main body structure includes a braided body and a polymer body. The braided body includes a carbon fiber, and the braided body has a network-like structure. The polymer body at least fills a gap of the network-like structure of the braided body so that the braided body and the conductive structure form an integrated structure.
