The Lange 1 115.046, seen from the bench

The Grand Lange 1 Blue Italia, reference 115.046, features a white gold case of 40.9 mm housing the L901.2 manual-winding calibre developed entirely in Glashütte. The iconic asymmetrical dial displays hours, minutes, small seconds at 6 o'clock, power reserve indicator at 1 o'clock, and the patented large date in the upper right corner. The lug width is 20 mm. This model represents the resurgence of Saxon watchmaking tradition introduced in October 1994.
