When you approach the most upper echelons of watchmaking, you're no longer talking about a mere watch, these are carefully crafted timepieces that is much more a piece of art than some pricey accessory. One of the finest works in watchmaking this year came via A. Lange & Söhne with their 1815 Rattrapante Perpetual Calendar Handwerkskunst.

One look at that blue watchface and you'll immediately know that there's more to this story. Built in a limited run of 20 pieces, this Handwerkskunst is named as such due to the careful artwork required to create this design. The subdials are surrounded in a blue, starry expanse that features relief-engraved stars that complement the design of the moon-phase. 


Flip the watch over and you're greeted by an detailed engraving of Luna, the mythical moon goddess, who is surrounded in a ring of raised cloud and star reliefs in blue enamel. The design also happens to be a hinged cuvette that protects the sapphire caseback, which gives you a view into what looks like a miniaturized city, a 631 component movement that is built entirely in-house. 


To say the L101.1 caliber is exquisite is a massive understatement. Every immaculately crafted component and mechanism work together in harmony to power the functions of the watch that include a perpetual calendar, the time, moon-phase, chronograph, and an up/down power reserve indicator. Not only that, the watch is able to accurately indicate the month (including leap years) until the year 2100 and the moon-phase is configured to remain accurate for just over 122 years. 

The A. Lange & Söhne's 1815 Rattrapante comes in a white gold and only 20 watches were produced. 

€290,000 (approx. $348,000),
