The A. Lange and Sohne Lange 1 Moon phase in platinum features a 38.5mm case, sapphire-crystal caseback and luminous power reserve, hour and minute hands. The Lange 1 Moon phase also features patented outsize date and a hand stitched black crocodile strap. This watch has some minor blemishes that can be easily polished out but I prefer to keep it unpolished.
Case is 38.5mm diameter, 3 piece, in platinum.
Dial is silver with small offset dial, patented large date window, 72 hour power reserve indicator, white gold luminous hands, and moon phase. The Lange moon phase differs from most traditional moon phase as it is connected to the seconds hand and continuously advances given it extreme accuracy.
