Blancpain Villeret Quantième Annuel GMT 6670-3642-55B
About This Watch
The Blancpain Villeret Quantième Annuel GMT is one of the most complication-dense watches in the Villeret collection, combining an annual calendar, second time zone, and moon phase within the classical Villeret dress watch format. The annual calendar mechanism requires correction only once per year at the end of February, while the GMT function provides a second time zone readout via a 24-hour sub-dial. The caliber 67A5 manages to incorporate all three complications while maintaining a 72-hour power reserve. The white opaline dial arranges the multiple displays with the legibility and balance that defines the Villeret collection: day, month in apertures, date by central hand, second time zone at 3, moon phase at 6. The 40mm rose gold case keeps the watch refined and wearable despite the mechanical complexity within. Under-lug correctors preserve the case's smooth profile. For the traveling collector who wants a complete calendar, second time zone, and moon phase in a single classically elegant watch, the Villeret Quantième Annuel GMT is a remarkably comprehensive solution.
In-Depth Review
The Villeret collection represents Blancpain's commitment to refined watchmaking without unnecessary complication, and the annual calendar GMT variant exemplifies this philosophy perfectly. The 40mm rose gold case strikes an elegant balance between presence and wearability, while the white opaline dial maintains the understated aesthetics the Villeret line is known for. The caliber 67A5 movement, beating at 28,800 vph with a generous 72-hour power reserve, demonstrates the technical competence underlying the design. What distinguishes this particular model is its practical complication set: the annual calendar reduces adjustment frequency to once yearly, the GMT function addresses modern travel demands, and the moon phase adds a touch of horological poetry. The brown alligator leather strap reinforces the watch's versatility, equally at home with business attire or smart casual wear.
This timepiece appeals to collectors who prioritize utility and design coherence over maximalist complication. The ideal owner values the annual calendar's practical advantage over a perpetual calendar's complexity, appreciates the heritage associated with Blancpain's founding collection, and requires genuine GMT functionality rather than novelty. It suits executives, seasoned travelers, and watchmakers who respect traditional manufacturing while acknowledging modern lifestyle needs.
At approximately $24,000 on the secondary market, the Villeret GMT competes directly with Patek Philippe's Aquanaut Travel Time and Omega's Seamaster Planet Ocean GMT. While the Patek offers greater prestige, it sacrifices the annual calendar simplicity and approachability. The Omega provides superior water resistance and sports-oriented aesthetics, but lacks the understated elegance Blancpain delivers. For those seeking Swiss luxury with restrained design language, the 6670-3642-55B remains a compelling choice.
