Wearable Electronic Device with a Compressible Air-Permeable Seal

Embodiments are directed to a smartwatch including a housing that at least partially defines an internal volume, and a touch-sensitive display positioned at least partially within the internal volume. A front cover can be positioned over the touch-sensitive display and can define a front exterior surface. A seal can be positioned between the housing and the front cover and configured to transition between an uncompressed state and a compressed state in response to an increase from a first external pressure on the front cover to a second external pressure. In the uncompressed state, the seal has a first density and is air-permeable allowing an internal pressure of the internal volume to equalize with external air at the first pressure. In the compressed state, the seal has a second density, greater than the first density, and is configured to inhibit ingress of water at the second pressure.
