We kick off another splendid aestival week (look it up) with the GRAND LANGE 1. This 25th-anniversary edition is 2.5 mm larger than the classic LANGE 1. It’s such a subtle increase that it’s not noticeable to the human eye except when the two models are viewed side by side.
To celebrate the 25th anniversary the GRAND LANGE 1 is available in a 25-watch limited edition in white gold with blue accents. The special feature of the GRAND LANGE 1 is what doesn’t meet the eye, or at least not right away.
On the asymmetrical dial, the proportionally enlarged displays for the time, the outsize date and the power-reserve indicator are arranged so that they do not overlap. What at first seemed trivial had far-reaching consequences: Because the hand arbors had to be slightly shifted toward the periphery, it was necessary to develop a bespoke movement for this model.
The manually wound caliber L095.1 reflects the prominent dial architecture down to the smallest detail. The larger movement diameter of 34.1mm allows a more compact arrangement with only one spring barrel. Thus, in comparison with the LANGE 1, the case is thinner but the power reserve is still 72 hours.
Visible through the sapphire-crystal caseback, the movement consists of 397 parts painstakingly finished by hand. Seven of the 42 bearing jewels are seated in gold chatons secured with blued screws. The oscillator, composed of a classic screw balance and a Lange balance spring, is suspended beneath a hand-engraved balance cock. The “25th Anniversary” collection is discreetly integrated into a blue-filled motif: a framed 25 that echoes the Lange outsize date.
The argenté-colored, recessed dial has thermally blued steel hands and blue inscriptions and the watch comes on a blue alligator leather strap with a white-gold prong buckle.
