Piaget’s pursuit of ultra-thin calibres opened a new door to creative possibilities during the 60s and 70s. With an energetic explosion of colour expressed through Piaget’s creation from the era, stone dials certainly propelled the brand to a new level. The use of stone dials was first introduced in 1963, lapis lazuli, jade, opal, malachite, tiger’s eye, onyx, you name it, Piaget has got it covered. Paired with infinite possibilities of combination and style, the charm of these exquisite and unique designs were seen on the wrist of Jackie Kennedy, Elizabeth Taylor and Elvis Presley.

Extremely well-preserved from the era is the present yellow gold pocket watch sized at 38mm diameter. Paired with a minimalistic bullseye appeal thanks to the rich black onyx contrasting to the warmth of yellow gold, three rings of diamonds encircles a subtle feature of this timepiece. Indicating the hour with a single diamond with one minute hand, this is a highly rare mystery pocket watch from the 70s. While such design are seen mostly on wristwatches with integrated bracelet, only a handful of mystery pocket watch with stone dials have surfaced in the market.

Housed within this exquisite pocket watch is the ultra thin manual wind calibre 9P introduced since 1957 with a thickness of just 2mm. Boasting a strong case with crisp hallmark on the caseback and a flawless dial, it also comes with a matching yellow gold diamond-set chain that is ready for its next owner to style it with their own flair.
