1. A watch comprising:
a watch body comprising:
a detector; and
a watch band configured to be coupled to the watch body and comprising:
a substrate of an elastic material defining an opening configured to stretch to engage a post; and
a conductive layer comprising conductive segments extending along a surface of the substrate and configured to move relative to each other and change a resistance along a path through the conductive segments as the opening of the substrate stretches and engages the post,
wherein the detector of the watch body is configured to:
measure the resistance along the path through the conductive segments; and
perform an operation based on the resistance.
