I have an English KWKS pocket watch in a siver case. It has 1775 Hall Mark in the case,Birmingham hallmark and the silver hall mark. The movement is a very well made Lever escapement. It has the serial#1,107943. It also has written on it Pat. Pinion. It has the step balance bridge and the old style balance wheel.I am not sure of how to post pictures to this board but I can send them to someone wno may be able to help me ID this watch.
