Prescot, late 19th or early 20th century.
Ebauche intended for a lever watch with complicated work.(1)
Ebauche Marks: 10313 JP.(2)
Frame: 3/4 plate layout, the back plate is supported by four turned pillars and intended to be retained by screws. The underside of the back plate is punched 13 and has a shallow recess turned in the centre. The front plate is 4.3 mm thick and deeply recessed for underdial work, leaving a broad rim for the dial seating. A circular aperture is cut through the front plate probably to accommodate a barrel, with a bridge fitted across the aperture in the front plate recess. The bridge has a straight grained finish and the recess in the front plate is finished with a light circular scratching. The train pivot holes are drilled, and screw holes threaded.
Dimensions: diameter 44.6 mm, height 8.3 mm, pillar height: 2.3 mm.
Provenance: Presented by A.G.M. Clark in 1968. This gift comprises parts and movements used in connection with the manufacture of watches in London in the late 19th and early 20th century.
(1) Although it is difficult to be certain, the complication was probably repeating work.
