News: A. Lange & Söhne reveals 1815 Rattrapante Perpetual Calendar

A. Lange & Söhne unveiled its 1815 Rattrapante Perpetual Calendar a decade ago, another technical milestone from this much-praised German brand that shows no fear of tackling the crème de la crème of prestigious complications.

To celebrate the watch’s tenth anniversary they’ve released this outstanding version in 18k white gold with a rose-gold dial (the brand prefers not to use the term “salmon pink”, thank you very much).

Naturally, this being Lange, no corners are cut here. Hands and markers are a mix of rhodiumed gold, blued steel and rhodiumed steel, and the four subdials are symmetrically positioned for a harmonious aesthetic. As well as the standard two chronograph pushers, an additional pusher at 10 o’clock operates the rattrapante—aka split seconds—function.

Powering this is the very same hand-wound L101.1 movement found in previous models—a movement that won the grand complications category at the Grand Prix d'Horlogerie in Geneva in 2013.

The small seconds subdial at 6 o’clock incorporates the moonphase display while the 30-minute chronograph subdial at 12 o’clock also accommodates the power reserve indicator. At 42-hours the power reserve on this watch is hardly generous, but this is a superb piece its fortunate owner will enjoy engaging with when manually winding it every other day or so.

This is limited to just 100 pieces.
