Got yesterday this watch. Still didn't had time to clean it.
Hallmarks identifies it as Swiss made, assayer mark seams to be from Geneve, imported to England at 1915.
Enamel dial, blued hands, silver case with double back doors.
Not sure if chronograph second hand is original.
Size is 35 mm without the crown, dial is 30mm wide, caliber seems to be 13 lignes
Any guesses on maker? Would appreciate any feedback.
