Introducing the A. Lange & Söhne 1815 Tourbillon with Enamel Dial
With the caliber L102.1, Lange put together two of their own patented mechanisms — the Zero-Reset and Stop-Seconds — into a manual wound tourbillon movement.
Lange introduced the Zero-Reset mechanism in 1997, with the Langematik. The mechanism is such that when the watch’s crown is pulled out to the time setting position, the running seconds hand jumps back to zero and stays stationary, while the time is adjusted. As a result, when you have set the desired time, you can zero it with another time source and push back the crown to let it start running just then.
Marked to be produced in a limited run of 100 pieces, the platinum cased version shares nearly all of the dimensions of the original save for the height of the watch, which is now 11.3mm. The pink gold cased version is 0.2mm slimmer at 11.1mm. The excess height results from the enamel dial that is ever so slightly thicker than the regular solid silver dial. Point of interest: Even the number 12 is red enamel, making this quite the complex dial that has to be achieved with multiple layers of enameling.
