IDENTIFIERS ----------- id: 207301 accession number: PW.32-1923 DATE AUDIT ---------- created: Wednesday 9 December 2015 updated: Wednesday 14 March 2018 DESCRIPTIVE DATA ---------------- object type: Verge watch in silver open face case. This is a good example of the verge watch in its last stages of development, as indicated by the seconds hand and the comparative flatness of the movement. MOVEMENT: Full plate movement engraved on barrel bar 'North No. 5671 Lombard Street LONDON'. Balance cock with table pierced and engraved with two birds, urn on pillar on neck. Cock foot engraved. Blued steel end piece, diamond end stone. Underside of foot stamped 'I' and scratched 'X503' and '13583'. Polished steel balance. Slide plate engraved, silver regulation disc marked 10, 20 and 30 in Arabic figures. Barrel bridge with engraved chamfered edge. Turned fusee iron post, polished steel winged case bolt, in slot in plate, nib in brass edge. Potance with moulding at end of foot, screwed, counter-potance riveted to plate. Stop lever pin to contact contrate wheel. Pillar plate with four turned pillars ringed at ends. Centre wheel recessed. Third wheel bar. Stop lever, slit in pillar plate for pin to stop contrate wheel. Fusee and chain, set-up click under dial. Verge escapement. Train planted clockwise. A balance stop is fitted, operated by a nib on the edge of the movement. Moving this brings a frictional brake into contact with the contrate wheel, and so stops the hands. As the verge escapement is self starting, the watch is ready to go again as soon as the brake is taken off BRASS EDGE: Plain gilt brass, three feet, recess for stop lever. DIAL: White enamel on copper, three feet. Ladder minute ring, diamond marks at quarters, radial Roman chapters. Seconds dial at 6 o'clock, with ladder seconds ring, long 5 second lines, radial Arabic figures every 10 sec. HANDS: Gold, poker and spade. CASE: Silver, plain, double-backed. Cover and dome London HM 1848. Maker's mark of a round cameo 'RO' over 'JE'. Small (around 1mm) round 'V' punch mark. The nib can be operated by opening the front glass, without swinging the movement out, and it enables the watch to be used as a stop watch. title: watch NOTES ----- type: history note value: Unknown before S.G.
