One of the few existing full size replicas of Giovanni de'Dondi's Astrarium, the fabled clockwork driven 14th century mechanism showing the movement of sun, moon and the planets.
The collection includes one of the early marine chronometers by Ferdinand Berthoud, a pendule sympathique by Breguet, a pocket watch with astronomical indications by Auch, several bespoke late 20th century watches by George Daniels, one of the few reproductions of the astrarium by De Dondi to name just a few highlights.
