Published in 1994 to celebrate 120 years of Piaget, Montres et merveilles de Piaget, 1874-1994 was written by Franco Cologni, Giampiero Negretti and Franco Nencini. Across 263 pages, the authors dig through the Maison's history using watches, movements, technical documents, period photographs, advertising and jewellery.

The book holds plenty of surprises.

One of the most striking is a 1959 gold watch powered by the calibre 6N. It came with six interchangeable coloured bezels, designed to be swapped and matched with different straps. A remarkable feat for 1959.

Elsewhere, the book reveals early shaped automatics, unusual bracelet constructions, pendant watches, extravagant jewellery pieces and plenty of Piaget creations that rarely get the spotlight today.

More than a greatest-hits collection, it feels like opening the Piaget archives and seeing just how much the Maison experimented over 120 years.

263 pages, 120 years, and more than a few Piaget pieces rarely seen before.
