Overview
The Lange 1 Tourbillon Perpetual Calendar “Lumen”
The A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar “Lumen”, reference 720.035FE, in a 950 platinum case, 41.9 mm across and 13 mm high, with a black dial of sapphire crystal. Self-winding calibre L225.1 with tourbillon and perpetual calendar, on a black alligator leather strap with a platinum deployant buckle.
Lange presents the “Lumen” as a pairing of traditional watchmaking craft with contemporary design. The brand says its semi-transparent dial gives a view into the movement and lets every display glow in the dark. Lange limits this version to 50 pieces.
The movement is calibre L225.1, self-winding, with 685 parts and a reserve of 50 hours; the balance beats at 21,600 semi-oscillations an hour (3.0 Hz). Lange lists six functions, among them the tourbillon and the perpetual calendar, with the outsize date, day/night indicator, moon-phase display and day-of-week display. The case is 13 mm high and water resistant to 3 bar, with a sapphire glass case back. The strap is alligator leather, closed with a deployant buckle in the case metal.
For collectors
The “Lumen” runs on its own calibre, L225.1, and its case is 13 mm high, unlike the other Lange 1 Tourbillon Perpetual Calendar references.
