Watchman's and Tell-Tale Clocks
Partially verifiedClocks that record whether a night watchman made his rounds.
Movement & mechanism
- A rotating dial with movable pegs or a paper tape records each visit
- A key at each station, or a pin pressed at the clock, marks the time of the round
- Portable versions were carried and punched a paper disc
Identification
- A recording dial with pegs, or a paper disc holder
- Provision for station keys in portable versions
- Surviving paper discs are valuable documentary evidence
Terminology
- Tell-tale clock
- Watchman's clock
- Station key
Known variations

Collecting notes
Originality decides value and interest: check that movement, dial and case belong together, and prefer honest wear over refinishing. Movement work belongs with a clockmaker; cleaning a dial or case yourself commonly destroys the evidence that dates the clock.
