Overview

The Vacheron Constantin FiftySix Day-Date reference 4400E/000R-B436 is a 40 mm dress watch in 18k pink gold, presenting a silvered opaline dial that carries day, date, and power-reserve indications in a composed, legible layout. It belongs to the FiftySix collection, a line introduced in 2018 that draws its design vocabulary directly from a celebrated 1956 Vacheron Constantin reference, reviving the era's characteristic cushion-influenced case architecture and clean dial philosophy. Powered by the in-house Calibre 2475 SC/2, the piece represents the manufacture's commitment to integrating practical complications within an unambiguously classical aesthetic.

History

The FiftySix collection was launched in 2018 as a deliberate homage to a 1956 Vacheron Constantin timepiece widely regarded as a touchstone of mid-century Geneva watchmaking. The original 1956 reference had introduced a case silhouette and dial sensibility that proved influential within the manufacture's own history, and the modern line was conceived to make that heritage accessible in contemporary proportions. Reference 4400E/000R-B436 sits among the more complication-rich expressions of the collection, pairing the day-date function with a power-reserve display — a trio of indications that adds practical utility without disturbing the dress-watch character. Pink gold was chosen as the metal for this reference, reinforcing the warm, approachable tone that distinguishes the FiftySix line from Vacheron Constantin's more austere complications.

Notable points

  • The 40 mm 18k pink gold case references the softly cushion-shaped architecture of the original 1956 Vacheron Constantin model that inspired the entire FiftySix collection.
  • Calibre 2475 SC/2 is an in-house self-winding movement, reflecting Vacheron Constantin's manufacture status and its ability to develop complications entirely within the Manufacture des Cabinotiers in Geneva.
  • The silvered opaline dial accommodates three distinct displays — day, date, and power reserve — while preserving the uncluttered, dressy character central to the FiftySix design brief.
  • A power-reserve indicator is a notably practical addition for a dress watch, allowing the wearer to monitor the movement's state of wind without disturbing the dial's classical balance.
  • The FiftySix collection, introduced in 2018, marked a conscious effort by Vacheron Constantin to bridge its mid-century archival aesthetic with modern wearability and in-house mechanical content.
