Overview

The Lange 1 in a 38.5 mm case

The A. Lange & Söhne Lange 1, reference 191.025, in a 950 platinum case, 38.5 mm across and 9.8 mm high, with a rhodié dial of solid silver. Manually wound calibre L121.1 with outsize date and power-reserve indicator, on a black alligator leather strap with a platinum prong buckle.

This execution is in 950 platinum. The dial is rhodié in solid silver, and the strap is black alligator leather with a platinum prong buckle.

The Lange 1 is the model Lange calls the classic of its collection, crediting it with giving the whole watch industry fresh impetus. The brand points to two things: the layout of the dial and the outsize date. This reference carries both on a manually wound movement.

The movement is calibre L121.1, manually wound, with 368 parts and a reserve of 72 hours; the balance beats at 21,600 semi-oscillations an hour (3.0 Hz). Lange lists two functions, the outsize date and the power-reserve indicator. The case is 9.8 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

At 38.5 mm the Lange 1 is made in pink, white and yellow gold and in platinum on this one calibre, in the same case size and height. The choice between those executions is therefore one of case metal, dial and strap; the movement and the dimensions stay the same.
