A LOCK THAT COUNTS HOURS

CLOCKVAULT

Twelve brass faces ring one door. Each must be set to its mark. But the faces are coupled: turn one on a quarter and the next follows it forward a whole hour, while the one behind it falls back a whole hour. The last face you set is never the last one you need.
