According to Vacheron Constantin, the inspiration for its Métiers d’Art Mecaniques Ajourées collection (“ajourée” is French for “openworked”) came from the architectural design of 19th century European railroad stations — the Gothic arches and airy vaults of the Industrial Revolution, along with the distinctive railway wall clocks and their Roman numerals. The movement in these watches, Caliber 4400 SQ (“squellette”) is described by the company as “hand-sculpted,” featuring manual beveling, engraving, and straightening, fine interior angles and contrasting brushed and polished finishes. The outer rings (in black, gray, or blue; there is also a high-jewelry version with baguette diamonds on the bezel) are made of grand feu enamel. The white gold cases are 40 mm in diameter, and the movement bears the Geneva Hallmark.
