Size 12, 19J Rotherham.

English watches are still in very short supply but the few I am getting in are rather good.

This is another classic size 12, 19 Jewel Pin set Rotherham  and Sons of Coventry, it has a true English Lever escapement with a Breguet sprung cut compensating balance.

It is signed under the dial by Rotherham and on the movement:
