Sixty years of stone dials

The stone dial exists because a movement got thin. In 1957 Piaget introduced the 9P, an ultra-thin hand-wound calibre, and the millimetres it saved created room for something no printed dial could match: a slice of actual stone. By 1963 the house was cutting lapis lazuli, opal, tiger’s eye and malachite to roughly one millimetre and setting them on gold dress watches. The wearers tell you what those watches were: Jackie Kennedy owned a Piaget with a stone dial; so did Elizabeth Taylor.

Rolex arrived in the 1970s and made the genre collectible. Stone dials went onto the Day-Date and Datejust in small numbers, lapis, tiger’s eye on refs. 1601, 16018 and most often the Day-Date 18038, turquoise available on special order, and later onyx and marble. On some malachite and onyx examples the house omitted hour markers entirely, so nothing interrupted the stone. Today those dials trade at multiples of their standard siblings.

Then the genre went quiet, and recently it woke. Jaeger-LeCoultre put meteorite in the Master Calendar in 2015; Omega gave the Speedmaster a Gibeon meteorite face in 2016; Piaget brought meteorite to the Altiplano in 2019. Rolex returned turquoise to the Day-Date 36 in 2023 and carries pink opal in the current catalogue. In 2024, Cartier cut a carnelian dial for a 200-piece Santos-Dumont.

Reading that history, a pattern: stone dials have always been the small series inside great houses, the thing made in dozens while everything else was made in thousands. An edition of ten is not a departure from the tradition. It is the tradition, taken at its word.

Each of the ten stone pages on this site records its own chapter of this lineage; this essay is the spine that connects them.
