A. Lange & Söhne Grand Lange 1

Grand Lange 1 in rose goldIt’s been 18 years since A. Lange & Söhne put German watchmaking on the map with its now-iconic Lange 1 model. The collector community took notice of its boldly off-center dial design and large date, as well as traditional Saxon elements in the movement, like the three-quarters plate, screwed gold chatons and screw balance, and the watch quickly became the foundation of Lange’s collection. This year, the Lange 1 gets a big brother, the Grand Lange 1, which boasts not only a larger case (40.9-mm diameter, as opposed to the original’s 38.5 mm) and elegantly scaled-up dial design, but also a brand-new manufacture movement, Lange’s hand-wound Caliber L095.1.

Because the movement is larger than the Lange 1’s Caliber L901.0, the dial architecture of the Lange 1 can be transposed onto the larger, solid silver dial of the Grand Lange 1 without any overlapping of elements. The hours and minutes remain on the large subdial at 9 o’clock, the running seconds on the subdial at 5 o’clock, the power reserve hand at 3 o’clock, and the “outsize” date window (which has also been enlarged by the same factor as the dial itself) at 1 o’clock.

From a technical standpoint, the bigger diameter of the new caliber (34.1 mm) also allowed Lange to arrange more parts on one level; the result is that Caliber L095.1 is only 4.7 mm thick. Another advantage of the larger dimensions is that the watch can achieve a 72-hour power reserve by using only one space-saving mainspring barrel. Of course, the case — which is available in yellow gold, rose gold, or platinum — is also correspondingly thin despite its large diameter: 8.8 mm thick.

The yellow-gold and rose-gold models are $39,300 and the platinum model is $53,200.
