This is my audio-visual story to present you one of the most spectacular wristwatches ever made. Please enjoy the photos, the HD-video and the recording of the sound of the striking mechanism.
During your career as a watch journalist you get to see a lot of amazing watches. Over the years you somehow get used to it and for the brands it gets more and more difficult to impress you.
Guys, yesterday I was impressed!
I only once before saw the A. Lange & Söhne Grand Complication live; this was last January at the SIHH in Geneva.
Now almost a year later I rediscovered the Grand Complication again. What a privilege to do this together with Anthony de Haas, Head of Product Development at A. Lange & Söhne! The Grand Complication is one of Anthony´s ticking babies, so believe me no one else could have been a better colloquist for me.
So after sifting my material this is what I can offer you:
You can discover the A. Lange & Söhne Grand Complication from A to Z.
And this is what you have to do:
Take some time and listen to our conversation, while using my photographs to discover all the details Anthony and I talked about. Then listen to the second sound-file to discover the striking mechanism of the Grand Complication and then watch the short HD-video to see the monopusher type chronograph operating with its rattrapante function and jumping seconds (seconde foudroyante).
You are not fully convinced yet? So let me tease you: Beneath the lucidly configured enamel dial, the horological opus made in Saxony/Germany with the calibre designation L1902 incorporates scores of lavishly finished parts, bringing to life the most elaborate complications which the art of haute horlogerie has to offer: Chiming mechanism with grand (grande sonnerie) and small strike (petite sonnerie), minute repeater, split-seconds chronograph with minute counter and jumping seconds as well as a perpetual calendar with moon phase display.
The chronograph of the is a monopusher type (chronographe monopoussoir) with a rattrapante function and jumping seconds (seconde foudroyante). This rare supplementary function makes it possible to freeze stopped times to fifths of a second. A blued-steel hand on the lower subsidiary dial performs five jumps to complete each revolution along its five-second scale while the chronograph is running. Thus, the hand precisely emulates the balance frequency of 2.5 Hz.
The HD-video shows how to use the chronograph. First Anthony started the chronograph, then he stopped the split-second hand, then the reset of the split-second hand followed and finally the reset of the chronograph to zero. At “6 o´clock” you see the jumping seconds…
