Overview

The 1815 Tourbillon in a 39.5 mm case

The A. Lange & Söhne 1815 Tourbillon, reference 730.094F, in a 950 platinum case, 39.5 mm across and 11.3 mm high, with a black dial. Manually wound calibre L102.1 with tourbillon and ZERO-RESET mechanism, on a black alligator leather strap with a platinum deployant buckle. Lange limits this version to 50 pieces.

Lange says the 1815 Tourbillon is the watch in which it first paired the tourbillon, with a stop-seconds mechanism of its own, and the ZERO-RESET function. This reference carries both on a manually wound movement.

The movement is calibre L102.1, manually wound, with 262 parts, a reserve of 72 hours and a balance beating at 21,600 semi-oscillations an hour (3.0 Hz). Lange lists the tourbillon and the ZERO-RESET mechanism. The case is 11.3 mm high, 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.
