<p>A wrist-worn device clasp has a first side 20 and a second side 30 and secures a strap of the wrist-worn device. The wrist-worn device has a magnetic securing mechanism with a first magnetic part 100 on the first side and a second mechanical part 130 on the second side. The first magnetic part engages with the second magnetic part to secure the clasp. A magnetic sensor 110, such as a Hall effect sensor, detects whether the magnetic field of a third magnetic source 140 is above a threshold.</p> |
