A wrist-worn training computer includes one or more biosensors; a casing; a display lens positioned against the casing to form an interface between the display lens and the casing, and to enclose together with the casing an enclosed space between the casing and the display lens; a first part of an antenna of a satellite navigation receiver disposed within the enclosed space; and a gasket positioned along the interface between the display lens and the casing to seal the enclosed space. The gasket comprises electrically conductive material that forms a second part of the antenna.

Antenna arrangement for wrist-worn training computer

A wristband, an electronics module, and a wrist device are disclosed. The wristband and the electronics module form the modular wrist device. The electronics module, when mounted to the wristband, stiffens a structure of at least a portion of the wrist device in order to enable the wrist device to firmly attach against a wrist of a user and to enable optical heart activity measurement by the electronics module.
