With its graceful sleekness, the new 1815 time-only watch by A. Lange & Söhne reflects the horological principles of company founder Ferdinand Adolph Lange. This new hand-wound mechanical timepiece presents itself as a visibly enlarged new edition of what was the fifth Lange model of the new era when it had its debut in 1995.
The new 1815 watch unites the finest virtues of Lange watchmaking artistry. With a case enlarged to 40 millimetres and a new movement that fills it amply with a diameter of 30.6 millimetres, it fully complies with Lange’s commitment to “state-of-the-art tradition”. The engineers and product designers succeeded in preserving the balanced proportions of the timeless original in its larger sibling.

With a railway-track minute scale, Arabic numerals, and small seconds at 6 o’clock, the new 1815 inherits the style features of classic Lange pocket watches and transposes them to the wristwatch format in a contemporary manner.

With its 188 lavishly hand-decorated parts, the newly designed calibre L051.1 movement represents the very quintessence of Lange watchmaking artistry: three-quarter plate made of untreated German silver, hand-engraved balance cock, whiplash precision index adjuster, screwed gold chatons, thermally blued screws.
Inside the movement, a large glucydur screw balance beats with a frequency of 21,600 semi-oscillations per hour. When fully wound, the watch has a power reserve of 55 hours.

The case and the prong buckle of the new 1815 are made of 18-carat yellow gold, white gold, or pink gold. Its argenté dial is solid silver. Black numerals and the blued-steel lancet hands that are characteristic Lange hallmarks assure excellent legibility.

In a limited edition of 500 pieces, the A. Lange & Söhne 1815 watch is also available with a platinum case featuring a rhodié dial and rhodiumed-gold hands.
