Notes

Ship and cabinet chronometers by Omega first appeared in 1914. The BB 120 JS model was available with the ?Exact Time? plaque in four different languages: ?Heure Exacte?, ?Exact Time?, ?Ora Esatta? and ?Ora Exacta?. Very few of these chronometers have survived; the present lot is in original unrestored condition.
