Claim 9:
10. An electronic watch comprising:
a housing that defines an internal chamber of the electronic watch;
a cover coupled to the housing and defining a front surface of the electronic watch, the cover configured to move from a first position to a second position in response to an increase in pressure on the front cover;
a processing unit positioned within the internal chamber; and
a compressible seal positioned between the housing and the cover, the compressible seal configured to increase in density in response to the cover moving from the first position and to the second position; wherein:
when the cover is subjected to an ambient air environment, the compressible seal is configured to resist an ingress of water at a first water pressure and equalize an air pressure within the internal chamber with an air pressure of the ambient environment; and
when the cover is subjected to a submerged water environment, the compressible seal is configured to resist an ingress of water at a second water pressure greater than the first water pressure.
