Clocks are fairly expensive decorations. Requiring 2 Wood and 1 Iron to make, along with an Anvil, A Wood Detailer , and a Carpenter's Bench to make, the only indoor decoration that's more expensive to make would be Bird in a Golden Cage.

It is recommended that you place Clocks in Taverns , Tavern Rooms , Personal Rooms , and Dining Rooms to provide maximum effect.
