Christie’s Geneva to Auction a Jacob & Co. Astronomia Flawless Diamond Watch

From 18 to 30 May, Christie’s Watches Online: The Geneva Edit will offer a selection of remarkable timepieces curated from a refined circle of ultra-exclusive timepieces at the nexus of high watchmaking and high jewellery. A highlight of this auction is the spectacular one-of-a-kind Jacob & Co. Astronomia Flawless Diamond Watch.

The Jacob & Co. Astronomia Flawless Diamond watch has a ground-breaking 4-arm movement seemingly floating inside a sapphire crystal case.

Four unique mechanisms, one at the tip of each arm – a globe of magnesium representing Earth with hand-lacquered oceans and continents of white gold, a one-carat Jacob-cut spherical diamond with 288 facets, a patented triple-axis tourbillon, and an hours and minutes complication with a patented differential gear system – orbit around the 3.02-carat diamond crowning the vertical movement.

Jacob & Co. Astronomia Flawless Diamond Watch

The estimate of this unique JACOB & CO., sapphire triple axis tourbillon “Astronomia Flawless” with 3.02 carat D flawless diamond, Ref. A125.80.AA.UG.B, from 2022, has been set at CHF 200,000-400,000.

Introduced in 2018, the “Astronomia Flawless Diamond” remains a testament to JACOB& CO.’s incredible creativity, boldness and engineering genius – a feat of multidisciplinary mastery in high watchmaking.

At the centre of the watch, an unprecedented vertical four-arm movement that demonstrates next-level watchmaking prowess, both creatively and technically.

At the tip of each arm, an element which again evokes the sensibility for art and storytelling, a hallmark of JACOB& CO.: the patented triple-axis tourbillon; the likewise patented hours and minutes complication with timepiece-differential gear system; the planet Earth made from a globe of magnesium, with hand-lacquered oceans and white gold continents; and as the Moon, a spherical diamond with 288 facets achieved with the exclusive Jacob cut.

All four orbit around the 2.88-carat white diamond, a miniature solar system floating in a spectacular sapphire crystal case. The “Astronomia Flawless Diamond” is a one-off piece that dazzles by its presence and by its substance.

The triple-axis tourbillon is at the forefront of modern watchmaking. The delicately decorated cage encapsulates the balance wheel, hairspring, escape wheel and several other important components.

Characterised by an open-worked cage, the JACOB& CO. tourbillon rotates on three axes simultaneously, a constellation of superbly finished components that ensures the Astronomia calibre’s absolute accuracy throughout the 60-hour power reserve.

A vast number of lots from The Geneva Edit May 2023 online sale will be exhibited at the new Christie’s Geneva Office between 22 and 26 May.
