A single analog wall clock with a blank white face and plain black hands, photographed straight-on against a saturated mustard-yellow backdrop. Its glass is slightly fogged. Several translucent multivitamin tablets, in the speckled orange-tan of a real multivitamin, rest on the clock's lower rim and in front of its face.

Soft, diffused studio light from the upper left creates gentle shadows on the yellow. The camera is at eye level with a shallow depth of field. The mood is wry and skeptical, curious but unconvinced.
