Movement of watch, plain, with only cock engraved, large jewel bearings, by Adam Burdess; Coventry, England, typical of late 19th century; dia. 1½” (3.81 cm.).
The lever escapement was usual for English watches a century ago, the layout of the movement still based on the earlier verge watches. The balance is compensated for temperature changes and fitted with screws in its rim for exact adjustment.
This movement possesses one unusual feature: the keyless work patented by Adam Burdess in 1869. The lever at the bottom left is worked to and fro to wind the watch though the hands are set by turning the milled disc below the lever, which is not the best of arrangements. The barrel containing the mainspring can be seen below the plate marked ‘Coventry’.
