Grand Lange 1 Lumen

When it was first presented, it evoked excitement and kicked off a trend that soon found many imitators: the Lange outsize date. Together with the asymmetric dial, it elevated the LANGE  1 to the status of an icon of classic design. However, the secret behind the complex mechanism responsible for this unprecedented date display format remained hidden beneath the solid-silver dial. Now, the GRAND  LANGE  1 with the Latin attribute “Lumen” reveals this secret. The name of the timepiece, which comes in a limited edition of 200 watches in platinum cases, says it all. Parts of its dial consist of semi-transparent sapphire crystal. Only the outer ring and the surfaces of the displays for hours and minutes as well as small seconds are made of blackened silver. The sapphire crystal surfaces reveal the disc mechanism of the first outsize date that glows in the dark. Additionally, the time and the power reserve are also legible in the dark.
