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, this piece is in original unrestored condition.
