The watch is equipped by a new world-time complication
developed by Montblanc’s watchmakers at Villeret: two
globes turn in opposite directions and effect one complete
rotation in 24 hours. Encircling the two globes is a graduated
scale with the 24 time zones, which also indicates day/
night by means of contrasting colours. This complication provides
an instinctive way of reading the time zones. The use of
SuperLumiNova® on the continents improves the watch’s nighttime
visibility and performance.
