the wall of the housing defines a surface of the passage; and

a hydrophilic surface treatment is applied to the surface of the passage.

8. An electronic watch comprising:

a housing comprising a housing wall defining:

an interior surface defining at least a portion of an internal volume within the electronic watch; and

a passage extending from the interior surface and through a thickness of the housing wall and fluidly coupling the internal volume and an external environment, and

a cover coupled to the housing, a portion of the cover set apart from a portion of an exterior surface of the housing wall to define an interstitial space between the cover and the housing wall, the interstitial space configured to draw liquid from the passage to the external environment.

9. The electronic watch of claim 8 , wherein:

the electronic watch further comprises a pressure sensing component and a battery;

the internal volume is divided into at least a first volume and a second volume;

the pressure sensing component is positioned within the first volume;

the battery is positioned within the second volume; and

the passage fluidly couples the first volume to the external environment .

10. The electronic watch of claim 9 , wherein:

the electronic watch further comprises a wireless charging component; and

the cover is a rear cover positioned over the wireless charging component.

11. The electronic watch of claim 10 , wherein:

the electronic watch further comprises a display and a front cover positioned over the display and coupled to the housing wall;

the passage is a first passage and the interstitial space is a first interstitial space;

the electronic watch defines a second interstitial space between a portion of the front cover and a second portion of the exterior surface of the housing wall, the second interstitial space fluidly coupled to the external environment; and

the housing wall defines a second passage extending through the thickness of the housing wall, the second passage fluidly coupling the internal volume to the second interstitial space.

12. The electronic watch of claim 8 , wherein the interstitial space extends along a perimeter of the cover.

13. The electronic watch of claim 8 , wherein the passage extends diagonally through the thickness of the housing wall.

14. The electronic watch of claim 8 , wherein:

the passage defines a diameter; and

a distance of the interstitial space from the cover to the housing wall is less than the diameter of the passage.

15. An electronic watch comprising:

a speaker;

a pressure sensor;

a processor;

a battery; and

a housing defining:

a first internal cavity, the first internal cavity housing the speaker and the pressure sensor;

a second internal cavity, the second internal cavity housing the processor and the battery; and

a capillary passage extending through the housing and fluidly coupling the first internal cavity with an external environment, the capillary passage configured to draw liquid from the first internal cavity to the external environment via capillary action.

16. The electronic watch of claim 15 , wherein:

the housing defines a side wall; and

the capillary passage extends through the side wall.

17. The electronic watch of claim 16 wherein the capillary passage comprises a porous drain structure.

18. The electronic watch of claim 16 , wherein the capillary passage is further configured to equalize a pressure of the first internal cavity to a barometric pressure of the external environment.

19. The electronic watch of claim 16 , wherein:

an exterior surface of the housing defines a recess;

the electronic watch comprises a wristband and an end of the wristband is positioned in the recess;

an interstitial volume is defined between a portion of the exterior surface of the housing and the end of the wristband; and
