Overview
The Lange 1 Perpetual Calendar in a 41.9 mm case
The A. Lange & Söhne Lange 1 Perpetual Calendar, reference 345.033 E, in an 18-carat pink gold case, 41.9 mm across and 12.1 mm high, with a grey dial. Self-winding calibre L021.3 with perpetual calendar, moon-phase display and outsize date, on a brown alligator leather strap with a pink gold prong buckle.
Lange describes the calendar displays of the Lange 1 Perpetual Calendar as jumping precisely when they change, with a month ring running around the edge of the dial. The brand presents the combination as its own mechanical and conceptual approach to the perpetual calendar.
The movement is calibre L021.3, self-winding, with 621 parts and a reserve of 50 hours; the balance beats at 21,600 semi-oscillations an hour (3.0 Hz). Lange lists five functions: the outsize date, the day/night indicator, the moon-phase display, the day-of-week display and the perpetual calendar. The case is 12.1 mm high, water resistant to 3 bar, with a sapphire glass case back. The strap is alligator leather, closed with a prong buckle in the case metal.
For collectors
The Lange 1 Perpetual Calendar is made in pink gold, white gold and platinum on this one calibre, in the same case size and height. The choice between those executions is one of case metal, dial and strap; the movement and the dimensions stay the same.
