1. An electronic watch comprising:
an enclosure;
a processing unit within the enclosure;
a crown assembly positioned along a side of the enclosure and comprising:
an actuation member comprising a shaft extending through an opening in the enclosure, the actuation member defining an input surface configured to receive a user input thereon;
a base structure positioned within the enclosure at an end of the shaft;
a collapsible dome coupled to the base structure and configured to collapse in response to a translational input applied to the actuation member;
a first conductive member coupled to the base structure and conductively coupled to the collapsible dome; and
a second conductive member coupled to the base structure, the second conductive member configured to conductively couple to the collapsible dome when the collapsible dome is collapsed, the second conductive member defining:
a portion of a first conductive path from the input surface, through the shaft, and to the processing unit; and
a portion of a second conductive path from the first conductive member and through the collapsible dome when the collapsible dome is collapsed, wherein
the processing unit is configured to:
determine a biological parameter of a user based at least in part on a first signal detected via the first conductive path; and
detect the translational input based at least in part on a second signal detected via the second conductive path.
