"In Catalonia in the 18th century, craftsmen began concentrating on making household clocks. Each one is engraved with the name of the town where they were made and they also have a part in common: an escape wheel, with characteristics that are not seen anywhere else in the world.
This clock was made in the workshop owned by the Roca family, from Arenys de Munt. Only 33 clocks from the workshop in Arenys de Munt exist today.
It works with a three-piece driving force, with a pendulum, anchor and Catalan escapement.
When the clock is fully wound it can run for one day; it strikes the hours and quarter-hours on two bells."
