The Saxon brand has been clear from the beginning of these series, since the first watch presented at SIHH 2019, there will be a total of 10 watches within the “Lange 1 25th Anniversary” series, so each of the 10 existing models in the Lange 1 collection will receive a commemorative edition.

The step 7 of 10 is The GRAND LANGE 1, 2.5 millimeters larger than the classic LANGE 1. The fact that the dial proportions are enlarged in comparison with the original is not visible, except when the two models are viewed side by side. To celebrate the 25th anniversary of the LANGE 1, the GRAND LANGE 1 is now also available in a 25-watch limited edition in white gold with blue accents.

The GRAND LANGE 1 “25th Anniversary”

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 calibre L095.1 reflects the prominent dial architecture down to the smallest detail. The larger movement diameter of 34.1 millimetres 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.

The argenté-coloured, recessed dial of the special model is graced with thermally blued steel hands and blue inscriptions. A blue alligator leather strap and a white-gold prong buckle emphasise the elegance of the watch.

Visible through the sapphire-crystal caseback, the movement consists of 397 parts lavishly 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 discreet signature of the “25th Anniversary” collection is integrated in its blue-filled motif: a framed 25 that echoes the Lange outsize date.

Larger, thinner, inimitable! The A. Lange & Söhne Grand Lange 1 25th Anniversary will be limited to 25 pieces. Its price will be 43.700 EURO.
