On the right: small cylindrical gilded clock, engraved with dragons around the side. On the left: detachable alarm bell on a gilded stand. This drum-shaped gilt-brass table clock has a spring-driven movement, horizontal dial, single steel hand and chapter ring marked with Roman hour numerals I-XII. The clock has a separate alarm mechanism, which rests over the dial in use. The alarm bell rings when the hand reaches the time that the alarm is set to go off and a detent (trip lever) is released. The clock is small and portable and the alarm can be detached when travelling. The drum is chased with dragons and foliate ornament and stylistic evidence suggests that the clock was made in France, possibly by the maker Guillaume Javin, of Avignon (c.1540-89). Both clocks are gilded and made of copper alloy and steel.
