Compressible seal for rotatable and translatable input mechanisms

A watch, comprising:

• a housing defining an opening and an aperture;
• a display positioned within the opening;
• an input mechanism having a shaft positioned at least partially within the aperture, the input mechanism configured to rotate without tactile feedback;
• a tactile dome switch configured to actuate in response to an inward translation of the input mechanism;
• an optical sensor positioned along a side of the shaft and configured to produce an output that varies in response to a rotation of the input mechanism;
• a first O-ring gasket positioned between a surface of the shaft and a smallest diameter portion of an inner surface of the aperture;
• a second O-ring gasket positioned between the surface of the shaft and the smallest diameter portion of the inner surface of the aperture, the second O-ring separated from the first O-ring gasket by an offset;
• and
• a processing element configured to modify an output of the display in response to each of:
• the actuation of the tactile dome switch due to the inward translation of the input mechanism;
• and
• the output of the optical sensor in response to the rotation of the input mechanism.

A watch comprising:

• a housing defining an aperture that extends from an external surface to an internal surface;
• a display positioned at least partially within the housing;
• an input mechanism comprising a shaft that extends through the aperture;
• a first gasket positioned along the shaft at a first position within the aperture;
• a second gasket positioned along the shaft at a second position within the aperture, the first and second positions located at a smallest diameter portion of the aperture and separated by an offset;
• a tactile dome switch configured to detect a translation of the input mechanism;
• and
• an optical sensing element configured to detect a rotation of the input mechanism;
• wherein:
• the first and second gaskets are configured to support the input mechanism within the aperture of the housing during the translation of the input mechanism and the rotation of the input mechanism;
• and
• an output of the display is responsive to each of:
• the translation of the input mechanism;
• and
• the rotation of the input mechanism.
