Overview
An ultra-thin perpetual calendar, read entirely by hand
The Vacheron Constantin Patrimony Perpetual Calendar Ultra-Thin, reference 43175/000R-9687, in 18K pink gold, with a silver-toned opaline dial, a starry-sky moon phase, on a brown alligator strap with an 18K pink gold triple folding clasp. Self-winding calibre 1120 QP, 41 mm, 8.91 mm high, certified to the Hallmark of Geneva.
This execution is the same Patrimony Perpetual Calendar Ultra-Thin case and calibre 1120 QP movement, in the same 18K pink gold, with a silver-toned opaline dial rather than midnight blue and a moon phase the page describes as a starry sky with two gold moons rather than the champlevé enamel sky. The strap is brown alligator leather rather than dark blue.
This is Vacheron Constantin's Patrimony Perpetual Calendar Ultra-Thin in 18K pink gold, a 41 mm case, 8.91 mm high, water-resistant to 30 m with a transparent sapphire case back. The calendar is read entirely by hands rather than through apertures: hours, minutes, a hand-type day and month, and a leap-year counter running to 48 months, set out on a midnight blue, sunburst-finished dial with a 'pearl'-style minute track built from 48 polished 18K gold pearls. At the dial's centre, an 18K gold moon disc carries a champlevé enamel sky with two hand-decorated moons. The brand states the calendar mechanism keeps correct until the year 2100.
The self-winding calibre 1120 QP is an ultra-thin base fitted with the perpetual calendar module: 29.6 mm across and 4.05 mm high, with 276 parts and 36 jewels, running at 19,800 V.P.H. (2.75 Hz) for a stated 40-hour power reserve. The watch is certified to the Hallmark of Geneva, the mark the Republic and Canton of Geneva introduced in 1886, which the brand ties to reliability and traceable origin rather than to any one technical detail. The case back is transparent sapphire, closed by an 18K pink gold triple folding clasp on the strap.
For collectors
The calendar is shown entirely by hands, with no date aperture and no window-style readout for day, month or leap year — unlike the standard-production Patrimony Self-Winding elsewhere in this bundle, which shows its date through a simple aperture.
