Wrist-borne structures (such as watches) include: (a) a wrist band assembly defining a recess and a first aperture; (b) an electronic or mechanical device assembly having a first control element positioned in the recess so as to be accessible at the first aperture; and (c) a first user interaction element engaged with the first control element via the first aperture. The first user interaction element may be at least partially located external to the recess and at least partially on an opposite side of the recess from the first control element. Methods for assembling watches or other wrist-borne structures like those described above also are described.
