A. Lange & Söhne GRAND LANGE 1

Prestigious German haute-horlogerie manufacture A. Lange & Söhne has released a new generation of its GRAND LANGE 1 watches.

With the first outsize date integrated in a wristwatch and the off-centre dial displays, the A. Lange & Söhne LANGE 1  instantly became a design icon when first presented to the public in 1994.

The GRAND LANGE 1 was introduced in 2003 for the aficionados of exquisite, mechanical timepieces who prefer slightly larger cases. With a case diameter of 41.9 mm, it is larger than the iconic LANGE 1  watch. Available in gold and platinum case versions, the first generation GRAND LANGE 1 watches usually sport a dual-tone dial design.

Released this year, the new GRAND LANGE 1 references feature reworked, mono-tone dials. Until recently, the implementation of the delicate azuré grooves – a relief structure composed of concentric circles – on the larger dial with the hour and minute indication was thwarted by technical constraints. Meanwhile, a new tool has made it possible to apply this noble decoration on larger-diameter areas as well.

The new GRAND LANGE 1 watch is available in yellow gold, pink gold, and platinum with matching monochrome solid-silver dials in champagne, argenté, and rhodié.

The exclusive manually-wound movement (calibre L901.2) is superbly finished to Lange’s highest quality standards, the twin mainspring barrel for a power reserve of more than three days, the progressive power-reserve indicator, and the patented outsize date.
