The community take
Owners talk.
Owners and reviewers widely praise the A. Lange & Söhne 1815 Rattrapante Perpetual Calendar for its beautiful pink gold dial and pocket watch-inspired layout, which offers flawless readability. The 636-part L101.1 manual-wind movement is a highlight, featuring German silver plates, a hand-engraved balance cock, and screwed gold chatons. Some find the rattrapante activation at 10 o'clock to be an unconventional design choice. The 41.9mm case is considered a reasonable thickness at 14.7mm for its complications, and its price is noted as significantly lower than comparable models from other high-end brands. On balance, owners and reviewers rate the A. Lange & Söhne 1815 Rattrapante Perpetual Calendar highly for its exquisite finishing and traditional aesthetic.
