Silver filigree pair-cased verge watch with date indicator

Description — British Museum

Movement frame: Circular gilt-brass plates with four pierced tulip pillars. Riveted potence and riveted counter-potence. Engraved decoration around the verge aperture. Four lugs in the edge of the pillar-plate engage in recesses in the case band. There is a potence-hole in the pillar-plate but the short potence does not pass into it because the deep set second wheel is in the way. Mainspring & set-up: Gilt-brass barrel with snap-in cap and riveted steel hook. Tangent-screw set-up on the potence-plate, the worm gear held by two cut-steel brackets. Fusee & stop-work: Gilt-brass fusee with chain and English stop-work. Train: Four wheel train of brass wheels, the second and third wheel with three crossings, the contrate with four. The second wheel is planted almost in the centre of the plate. Escapement & balance: Verge escapement, the crown-wheel ungilded, the verge and balance replaced. Screwed-on balance cock, pierced and engraved with scrolling foliage. Dial & hand: Around the outside a separate pinned-on ring is engraved 1-31 for the date. Within this a rotating ring carries a pointer to indicate the date. In the centre the pinned-on dial has Roman hours I-XII and foliate half-hour marks surrounding a quarter-circle. In the middle of the dial is an engraved landscape with a castle in the background and two standing figures in the foreground. Pinned-on single blued-steel hand. Cases: Plain silver inner case with a rotating winding-hole cover. Plain silver hinged bezel, split and glazed. Silver pendant with loose ring. Silver filigree outer case.
