Record-Thin: 1.2mm Altiplano, cal20P

Piaget Record- & Ultra-Thin Altiplano: 1.2mm, Factory-Serviced ref222


CHF 7,000

WHY WE LOVE IT: With just 1.20mm it is the thinnest manual-wound movement in the '80s, '90s and 2000s until the RM-UP01 beats it with 1.18mm (!sic, so just 0.02mm less) in 2022. A legend!

Altiplano Ultra-Thin -- Rare & Important: The Piaget cal20P held the world-record for the thinnest mechanical caliber (1.20mm) since 1980s until the Richard Mille RMUP01 took it by 0.02mm in 2023 (!sic) -- so more than 40y later. The case is 3.4mm thick and the RM is significantly thinner just because the case-back is the mainplate (same as with the Delirium, innovated by Maurice Grimm and André Beyner), while the Piaget uses classical encasing of the movement. But the sheer height of the now celebrated RMUP01-caliber is basically the same as the 40y ago-designed Piaget cal20P. A horological milestone and a decade-long worldrecord in the most important horological complication: miniaturisation.

Manufactured in 1982 according to our research and so one of the first Piaget using the cal20P. Serviced in 2024 by Piaget, Switzerland and thus coming with a 24months warranty. The case is in very good and unpolished condition -- polishing was explicitly excluded from the service to keep it in a homogenous (dial & case with signs of time), sharp and authentic condition. The dial shows some signs of time and oxidation as well but we also decided to keep it like that and not ask Piaget to refurbish it during the full service.

Coming in its original box and a high quality custom-strap connecting the original 18K buckle.
