Various traditional elements like the minuterie, blued steel hands, Arabic numerals, screwed gold-chatons or sunk dials are reminiscent of the timepieces’ rich heritage.
The dial facet has lots of other treats for the onlooker, particularly people linked into the perpetual calendar and also the rattrapante chronograph. The former consists of 206 components, nearly a third of their 684 total element count of the L133.1 caliber. Lange’s moon stage is “true to 122.6 years” — mind you, which “accuracy” means that it takes that much time to get the moon phase screen to be off by a comprehensive moment. This form of arbitrary way is how the precision of moon phase displays in watches is usually determined, not that anybody really cares about real practicality beyond its aesthetic and technology element.The rattrapante chronograph on the other hand is one of the most technically impressive and hard complications out there. Some watchmakers I asked told me that they find it even more challenging to perform than a sonnerie or minute repeater, and definitely a much bigger pain in the neck than a perpetual calendar (unless it is instantaneous or further complex). Both laser sharp chronograph seconds palms rest a hair’s width over one another in their own reset place, with all the blue being the rattrapante hand, operated by the pusher at the 10 o’clock position of this circumstance.
