Opening Context
The Harmony collection was introduced by Vacheron Constantin in 2015 as part of the maison’s 260th-anniversary celebrations, drawing inspiration from a cushion-shaped chronograph produced in 1928. Its softly curved case offered a distinctive alternative to the traditional round architecture of the Patrimony and Traditionnelle families. The Harmony Dual Time 7810S/000R-B141 applies this elegant form to a practical travel complication, combining an 18K 5N pink gold case with a second time zone and day/night indication in a refined, distinctly Vacheron Constantin interpretation of the traveller’s watch.
Why This Reference Matters
The Harmony Dual Time is immediately recognisable through its unusual cushion-shaped case. Measuring 40 × 49.3 mm, its broad curves, short lugs, and gently rounded geometry create an architectural presence quite different from Vacheron Constantin’s conventional dress watches. The warmth of 18K 5N pink gold further emphasises the sculptural quality of the design.
Its silver-toned opaline dial balances this unconventional case with a restrained, highly legible layout. Arabic numerals give the watch a slightly more relaxed character, while the second-time-zone indication allows the wearer to track another location independently from local time. A dedicated day/night indicator provides immediate context for the second time zone, making it particularly useful when travelling or communicating internationally.
At its heart is the automatic Calibre 2460 DT, developed around Vacheron Constantin’s manufacture movement architecture specifically to accommodate the dual-time functionality. Offering approximately 40 hours of power reserve, it combines self-winding convenience with a complication designed for genuine everyday utility.
On the Wrist
Although its 40 × 49.3 mm dimensions suggest considerable size, the Harmony’s cushion-shaped architecture creates a very different impression from a similarly dimensioned round watch. The curved case distributes its visual mass across the wrist, while the absence of conventional elongated lugs helps maintain a cohesive silhouette. The 18K pink gold provides substantial precious-metal presence, balanced by the understated silver-toned dial. A black leather strap introduces a formal contrast and is secured by an 18K pink gold triple-blade folding clasp, completing the refined presentation.
Condition & Transparency
This example features a 40 × 49.3 mm cushion-shaped case crafted from 18K 5N pink gold, paired with a silver-toned opaline dial displaying Arabic numerals, a second time zone and day/night indicator. It is powered by the automatic Calibre 2460 DT, offering approximately 40 hours of power reserve, and is fitted to a black leather strap with an 18K pink gold triple-blade folding clasp. Particular attention should be given to preservation of the distinctive case geometry and original finishes, dial and numeral condition, movement performance, correct adjustment and alignment of the dual-time indication, day/night functionality, strap condition, folding-clasp operation, and overall set completeness—communicated strictly on verified information.
Why It Belongs in a Collection
The Harmony Dual Time 7810S/000R-B141 appeals to collectors seeking Vacheron Constantin in a form that is both historically informed and visually different from the maison’s better-known round watches. The Harmony case gives the reference a strong identity, while the dual-time complication provides genuine practical value rather than complexity for its own sake. Its association with the collection created for Vacheron Constantin’s 260th anniversary adds another layer of historical context. Within a thoughtfully curated collection, it offers an appealing combination of shaped-case design, useful complication, precious-metal craftsmanship, and modern Genevan haute horlogerie.
Closing
The Vacheron Constantin Harmony Dual Time 7810S/000R-B141 is an elegant and distinctive interpretation of the mechanical travel watch. Combining its sculptural 18K 5N pink gold Harmony case, restrained silver-toned opaline dial, practical second-time-zone and day/night displays, and automatic Calibre 2460 DT, it demonstrates Vacheron Constantin’s ability to unite historical inspiration with contemporary functionality—creating a watch that is recognisably classical in craftsmanship yet refreshingly unconventional in form.
