Overview
A satellite-hour dial for the Cape of Good Hope scene
The Vacheron Constantin Métiers d'Art Tribute to Explorer Naturalists, reference 7500U/000R-B992, in 18K pink gold with a hand-engraved and enamel dial depicting the Strait of Magellan, on a dark blue alligator strap. Self-winding calibre 1120 AT with hours shown by satellite display; 41 mm, 11.73 mm high; Hallmark of Geneva.
This execution depicts the Strait of Magellan, in an 18K pink gold case, on a dark blue alligator leather strap closed by an 18K pink gold triple folding clasp.
This reference is one of four pieces in Vacheron Constantin's Métiers d'Art Tribute to Explorer Naturalists series, which the brand presents as four limited editions of ten pieces each, framed as inspired by the sea voyages naturalists made during the Beagle's expeditions in the early 1830s. This execution, in 18K pink gold, depicts the Strait of Magellan: the dial's upper register carries hand-engraved animal figures raised against a Grand Feu enamel ground, and the lower register holds a map of the strait rendered in miniature Grand Feu enamel, with hours shown through a satellite display, minutes by hand, and the hour-markers in Arabic numerals. The case is 41 mm across and 11.73 mm high, water-resistant to 30 m, with a transparent sapphire case back; this piece is worn on a dark blue alligator leather strap.
The self-winding movement is the calibre 1120 AT (Vacheron Constantin also calls it the 1120AT/1); it measures 32.8 mm across and 5.45 mm high, built from 205 parts with 36 jewels, running at 19,800 V.P.H. (2.75 Hz) for a stated 40-hour power reserve. The movement carries the Hallmark of Geneva, which Vacheron Constantin dates to 1886, when the Republic and Canton of Geneva adopted the mark as a Geneva-watchmaking quality standard that it says still stands for craftsmanship, reliability and origin today.
