Case: Gilt-brass tambour case, the band engraved with Moresques enclosing foliate motifs. The push-on base has ringed decoration on the inside. The outside is decorated with a border similar to that around the band and enclosing a left facing portrait bust of a classical warrior wearing a helmet.. Part of the case band has been cut away at the bottom. Dial: The dial is integral with the case band and has a raised rim decorated with wheat-ear motifs. Around the outside of the recessed dial are a circle of touch pins at the hours. The chapter ring has hours I-XII with * half-hour marks and an inner circle 13-Z4 with single-dot half-hour marks. The steel hand is not original. Movement: All steel movement with three shaped pillars rivetted to the back plate. The front plate is retained by pins. The open mainspring is attached at its outer end to one of the movement pillars and there is a central steel post to restrict the expansion of the mainspring. On the back plate the stackfreed assembly consists of the usual stop-work, cam and spring and roller. Four wheel going train of steel wheels,, the second, third and contrate wheels with three crossings each. Verge escapement, with a very light steel crown wheel running in a single double ended clip attached around one of the movement pillars. The verge pivots in the balance cock in the normal way and in a scroll-shaped steel cock rivetted to the front plate. Dumb-bell balance with a scroll-shaped balance cock, the repaired foot and retaining screw are not original. The aperture in the back plate is shaped with decorative corners. Hog's bristle regulator. The movement is retained in the case by two latches. The motion work consists of a pinion of report on the great wheel driving a central dial wheel. Detachable alarm : Case: Gilt-brass tambour case with three sprung feet which attach to the rim of the main clock case when the alarm is in use. The movement slides into the case and is retained by two screws, one of which is now missing. The release lever is pivoted on one of the three feet which attached the mechanism to the main clock case. Movement: All steel movement with a centrally mounted open mainspring hooked around one pillar. A large contrate wheel mounted on the mainspring arbor drives a crown wheel and verge escapement with the hammer mounted on the verge. The crown wheel pivots between a single double ended clip attached around one of the movement pillars. The bottom plate carries the pillars and the top plate is pinned. The alarm is locked by a spring-loaded sliding arbor of square section. Notes: 1. The hog's bristle regulator is perhaps not original, as there is no register of dots on the back plate against which it should indicate. 2. Two similar clocks exist in the British Musuem collections, one by Nicolas Lancz of Innsbruck dated 1549 (reg.no. MLA 1888,12-1.109) and the other punched with the maker's initials SZ conjoined (reg.no. MLA 188,12-1.108), both clocks formerly in the Octavius Morgan Collection.
