The Grand Lange 1, which, since its debut in 1994, has become the ambassador par excellence of A. Lange & Söhne, best encapsulates the spirit of this legendary German brand from Glashütte. Characterised by the large date window at 1 o’clock, the Grand Lange 1's double date window was directly inspired by the five-minute clock gracing the stage of the Semper Opera House in Dresden. The hours and minutes are displayed in an off-centred dial with Roman numerals and the small seconds are displayed in a dial at 5 o’clock. The AUF/AB indicator is a power reserve indicator and will let you know when the watch needs winding after a period of roughly 72 hours of impeccable performance thanks to the in-house manual-winding movement. This 40.9mm pink gold model has a slim profile with a height of just 8.8mm and you will be hard pressed to find a finer or more elegant classic mechanical wristwatch on the market today. Available at Watches of Switzerland.
