The process actually takes about 15 seconds. So much of what you get is watching the process take action. There are two hidden plates in the watch that act like a double scissors. These "close" and the upper and lower dials are covered over with grayish plates. At the same time the lower dial actually moves down like a little elevator. Internally the watch is going mad with gears and changes to make sure everything works properly. This is not a sport watch my friends, something that you are wise to be delicate with.After the change is complete the Arabic numeral dial for the hours is now replaced with Roman numerals. This dial and the minute hand still tell the time. The seconds hand is now a seconds hand for the chronograph, and the date display is now used for the chronograph minutes - which is quirkily labeled 1-31 for obvious reasons.
Over the date dial is a transparent bridge made out of synthetic sapphire. When you get bored of this, you can transform the watch into chronograph mode.Montblanc was wise to use the metamorphosis name for the watch. While in a sense it does transform, much of the detail is internal. So while the timepiece change is anything but Kafkaesque it is more of a change of face and function than a serious transformation *** you feel like you have something totally new on your wrist. The process of changing the watch is longer than you would expect. First you need to press the monopusher chronograph button in the crown, then slide the lever on the left s ide of the case.
