This museum, on on the first floor of the local château, is run by the Aliermont Clock and Watchmakers’ Association. The collections comprise some 300 items which retrace the history of clock and watchmaking in Saint Nicolas d’Aliermont since 1725, with household clocks (tall-case clocks, mantel clocks, alarm clocks, carriage clocks, wall clocks, etc), scientific and technical timepieces (marine regulators and chronometers), and time-control devices including ticket machines and all manner of time clocks. Visitors can also enjoy a presentation of local history featuring the use of old watchmakers’ tools.
