Before the chronometer, the mariner read the sky. The Celestial Navigator is an homage to that older science — a wrist‑borne astrolabe whose dial sweeps through a painted night: the green fire of an aurora, the silent dust of a nebula, a comet drawn across the dark.
At its heart, a gilt star‑rose turns beneath three classic hands. Turn the watch over and the heart itself is laid bare — a skeleton rotor orbiting a perlage‑finished calibre, visible through sapphire.
Each dial is painted by a single hand in the TechGrapple atelier, so no two nights are identical.
