An excellent late size 16 pin set movement by Rotherham and Sons of Coventry, it has a true English Lever escapement with a Breguet sprung cut compensating balance. It is jewelled as for a 15 jewel movement but with the addition of cap jewels on the lever and escape for a total of 19 and is equipped with functional Geneva stop gear
to control mainspring pressure. It is signed under the dial with the Rotherham trade mark and on the movement and face by Kemp of Bristol. Dated from the serial number to 1900.
The double backed case is in 14 Carat Filled gold, almost certainly by Rotherham.
