Overview
The Datograph Perpetual in a 41 mm case
The A. Lange & Söhne Datograph Perpetual, reference 410.136 E, in a 950 platinum case, 41 mm across and 13.5 mm high, with a rhodié dial. Manually wound calibre L952.1 with outsize date, day/night indicator, moon-phase display, chronograph, day-of-week display and perpetual calendar, on a 950 platinum bracelet with a platinum deployant buckle.
This execution is in 950 platinum, on a 950 platinum bracelet with a platinum deployant buckle. The dial is rhodié with diamond markers. Lange limits this version to 50 pieces.
Lange presents the Datograph Perpetual as its first wristwatch to hold a chronograph, an outsize date and a perpetual calendar in one case. It is made in white gold and in platinum on the same calibre.
The movement is calibre L952.1, manually wound, with 556 parts, a reserve of 36 hours and a balance beating at 18,000 semi-oscillations an hour (2.5 Hz). Lange lists the outsize date, day/night indicator, moon-phase display, chronograph, day-of-week display and perpetual calendar. The case is 13.5 mm high, water resistant to 3 bar, with a sapphire glass case back.
For collectors
The white gold and platinum versions of the Datograph Perpetual share calibre L952.1 and a 41 mm case 13.5 mm high. They differ in case metal, dial and what holds the watch on the wrist: a leather strap or a bracelet.
