Montblanc caliber MB 29.25

Caliber MB 29.25 is based on the Sellita SW300, fitted with an in-house module that features a worldtime complication with two turning domed hemisphere globes, which make a full rotation in 24 hours. The northern hemisphere at 12 o’clock turns anticlockwise, while the southern hemisphere turns clockwise. They are both surrounded by a scale with the 24 time zones, along with a day/night indication in contrasting colors.
