Have aquired a Swiss watch I believe to be Circa WW1. The movement is marked : Swiss Made, 15 Jewels, DF&C, Sets and runs OK ( 6,8,10 hours on one wind) but urgently needs a clean and service. Case is marked 925 Silver with London import mark and date mark b.  DBs at top.  On bottom is E7   107403.  The case is Hinged back and front.  The lugs are wire.   If someone more Clewed up than me could put a makers name, date and aproximate value  on this watch I would appreciate it.  Thanks for yor time.
