The **Grand Lange 1** (German: **Große Lange 1**) is a luxury watch by [[A. Lange & Söhne]].

For lovers of larger watches, this model is a variant of the [[Lange 1]] in a case with 41.9 mm diameter.

With the UP and DOWN display the winding state of the [[double barrel]] can be determined. Fully wound it features a power reserve of three days. Depending on the chosen model the hands are in gold or in [[blued]] steel.

Since [[2008]], there has been a new series of the **Grand Lange 1** with a revised dial.

[[2012]], the Große Lange 1 was again redesigned: the case became slightly smaller and a lot flatter, and it also received a movement developed from scratch, the caliber [[Lange L095.1|L095.1]].
