Vacheron Constantin 4000S/000R Harmony Complete Calendar 18K Rose Gold Silver Dial

Introduced in 2016, the Harmony Complete Calendar reference 4000S/000R-B123 is one of the most distinctive expressions of Vacheron Constantin's anniversary-era design language, pairing the collection's refined cushion case with a full calendar and precision moonphase display. Its 18K pink gold case gives the watch notable warmth, while the silver-toned dial preserves the formal, highly legible character expected of the Harmony line. The watch is powered by the self-winding caliber 2460 QCL, a Geneva Hallmark movement that reflects the brand's long-standing commitment to classical finishing and mechanical integrity. Collectors tend to value this reference for its balanced execution of useful complications, with day and month apertures, a hand-date display, and moonphase arranged in a manner that feels both traditional and unmistakably Vacheron Constantin. At 40 mm across with a notably elongated cushion profile on the wrist, it offers a dress-complication presence that differs meaningfully from the brand's more familiar round cases. The caliber itself is well regarded for its reliability, elegant architecture, and practical automatic winding, making the watch more versatile than many formal calendar pieces. Within the broader Harmony collection, this reference stands out as a less common and more nuanced alternative to simple time-only or chronograph models, appealing to buyers who appreciate restrained complication over overt sportiness. It was not a stated limited edition for a specific country or boutique, which only strengthens its appeal as a pure catalogue expression of the collection at its most classically composed. For collectors focused on modern Vacheron Constantin complicated watches with strong case design, a prestigious movement, and understated market visibility, the 4000S/000R-B123 remains a compelling choice.
