Help authenticate BREGUET & Omega pocket watches
Working my way through passed down collection of pocket watches doing ok with English & American but stumbling with these two .
BREGUET measures 32mm gold & silver case 5020 +as yet unidentified hallmark BREGUET name on movement but no s/no.
The Omega marked case 3055603 14U markings 45mm also has no s/no or make on face or movement but runs really well in spite of obvious tampering/repairs .having only a blued finish to the case is it likely two be services watch
Thanks for any suggestions
