The iconic LANGE 1 family added a big model in 2003 dedicated to those who love large sized watches.
The GRAND LANGE 1 now gets a make over by equipping new movement, balancing the dial lay out and slimming down the silhouette.
With a deliberate rearrangement of watch components, the totally new manually wound calibre L095.1 made it possible to transpose the graceful dial architecture of the LANGE 1 to the perceptibly larger model.
The hours, minutes, and seconds as well as the outsize date and power-reserve indication are configured on the solid-silver dial without any overlap points. To faithfully preserve the harmonious proportions down to the last detail, the Lange outsize date was also enlarged by the same factor as the dial itself.
Furthermore, the larger movement diameter made it feasible to arrange more parts on one level. The result is a movement height of merely 4.7 millimetres.
The impressive 72-hour power reserve was achieved in a space-saving manner with only one mainspring barrel. This had a positive impact on the dimensions of the new GRAND LANGE 1 case, which has a diameter of 40.9mm and 8.8mm thickness.
The sapphire-crystal caseback reveals the splendid manufacture movement, painstakingly decorated by hand and assembled twice. Embellished with Glashütte ribbing, the three-quarter plate made of untreated German silver assures optimised stability. Its gracefully curved cutout exposes the balance that beats with a frequency of 21,600 semi-oscillations per hour and is carried by the hand-engraved balance cock.
A proprietary Lange-made balance spring assures exceptionally high rate accuracy. Seven screwed gold chatons secure the ruby jewels, accentuating the visual appeal of the movement on the plate side.
The new GRAND LANGE 1 watch is available in yellow-gold, pink-gold, and platinum case versions. They respectively feature champagne, argenté and rhodié dials.
