It features a manufacture world-time complication created by Montblanc's watchmakers in Villeret: two domed globes (Northern and Southern Hemisphere) moving in opposite directions, each completing a full rotation in 24 hours, topped by a 24-time-zone scale and a day/night indicator. Luminescent continents improve visibility in the dark. The watch also shows a second time zone and the date.
