Equipped with the Calibre MB 29.19 with a highly functional Manufacture complication developed in-house by Montblanc, the Montblanc Heritage Chronometrie Dual Time indicates both local time and home time in an intuitive and easy to use way. The time at the home destination is displayed by a 12-hour home-time hand in blue and a rhodium-plated minutes hand. A 24 hour subdial at 12 o'clock indicates whether it is night or day at home. When travelling, the local time - displayed by the rhodium-plated hours hand - can be easily adjusted in one-hour jumps and in both directions with the crown in the second position, while the central minutes and the small seconds at 6 o'clock continue to run. The local time is linked with the date - a trusted companion not just for crossing the International Date Line.
