The movement, Caliber G1769, also has a flying tourbillon at 6 o’clock, which rotates on a ball bearing to substitute rolling for sliding friction. The inclusion of a tourbillon is another nod to Isaac Newton, as that invention was originally developed to counteract the effects of gravity on a watch’s precision. Caliber G1769 has manual winding, 29 jewels, an Incabloc shock absorber, and a 96-hour power reserve. It is visible through a sapphire window in the back of the 46-mm rose-gold case.
The blue dial drives home the astronomical theme with 45 diamonds — 34 on the dial, 11 on the painted sapphire bezel — arranged into the constellations Camelopardalis, Perseus, Cassiopeia, Ursa Major, and Ursa Minor, with the dial’s center representing Polaris, the North Star. The bezel is designed to resemble a view of the starry night sky through a refracting telescope. The skeletonized hour and minute hands are made of the same rose gold as the case, as is the pin buckle on the blue crocodile leather strap. The price of this extremely limited, highly complicated timekeeper is also what many would consider astronomical: $280,000.
