Introducing the A. Lange & Söhne 1815 Rattrapante Perpetual Calendar Handwerkskunst
Watches that have been previously bestowed the honor of the Handwerkskunst title, include the Richard Lange Tourbillon Pour Le Mérite Handwerkskunst (2011), the Zeitwerk Handwerkskunst (2012), Lange 1 Tourbillon Perpetual Calendar Handwerkskunst (2013), Tourbillon Lange 1 Handwerkskunst (2014) and the 1815 Tourbillon Handwerkskunst (2015).
The addition of Handwerkskunst, to one of their watch names, is Lange’s way of saying that they’ve taken their commendable reputation for traditional hand decorations and turned them up a great many notches.
Interesting detail to note here is that the engraving and, thereafter, the enameling is done with a lot of thought to the final thickness of the dial. Because as you can see the applied Arabic numerals sit flush with the top surface of the enamel.
But, of course, it’s not all flat and flush. There’s lots of spatial interplay on the dial with the outer minute track and all of the sub-dials executed with steps.
Of course, the little lip on the side of the caseback means that this is a hunter style caseback, which when you flip open, you will encounter the caliber L101.1 within. A completely integrated split-second chronograph movement with two column wheels — one to govern the chronograph hand and the other for the split seconds.
And as a standard, some of the movement’s bridges, such as the operating-lever, cover and chronograph bridges as well as on the rattrapante and balance cocks are relief and tremblage engraved to quite the visual treat.
As beautiful as the final watch is, what you must appreciate is that the 1815 Rattrapante Perpetual Calendar is already a very complex watch to produce. But adding the Handwerkskunst title throttles this difficulty to astronomical levels. Because the accuracy that the watch promises — perpetual calendar will not require adjustment until 2100; moon-phase will run accurately for 122.6 years — cannot be compromised as a result of decorative decisions.
As such, on the matter of the 1815 Rattrapante Perpetual Calendar Handwerkskunst, A. Lange & Söhne are committing to produce only 20 pieces of it.
