Vacheron Constantin Debuts First Minute Repeater in Overseas Collection

Summary

• Vacheron Constantin’s Overseas Grand Complication Openface is the first minute repeater in the Overseas collection
• It features a 44.5mm titanium case with a complex, openwork sapphire dial
• Its 2755 QP caliber includes a minute repeater, perpetual calendar and tourbillon

Vacheron Constantin has unveiled the Overseas Grand Complication Openface watch — the first minute repeater in the Overseas collection. It represents the culmination of a significant endeavor to integrate a grand complication mechanism into an elegant case.

Featuring a 44.5mm case diameter, the timepiece comes in a titanium build with a highly complex sapphire crystal dial. The dial showcases an openworked design, adorned with 18k white gold indices and hands. Meanwhile, the chapter ring and the day, date, and month counters all exhibit a sophisticated blue color, adding a touch of color to the watch face.

Viewable through the watch’s open caseback is the 2755 QP movement, which provides approximately 58 hours of power reserve. Despite its slim 7.9 mm thickness, the movement incorporates several complex complications. These include a minute repeater, a perpetual calendar, a tourbillon, and a power reserve indicator. Vacheron Constantin also paid particular attention to the aesthetics of the centripetal regulator — an arc-shaped bar crafted from gold that secures the regulator. Beneath it, the circular-grained inertia weights are engraved with the initials of Jean-Marc Vacheron, the founder of the Maison in 1755.

Water resistance typically presents a challenge for watches with a minute repeater function due to the sliding mechanism that activates the repeater. For this specific model, Vacheron Constantin ensured the water resistance of the Overseas case. This was achieved while adapting the case design to accommodate the caliber. This process involved 18 months of research and development, including a complete redesign of the caseback to accommodate the minute repeater mechanism, all the while preserving the characteristic slender curves of the series

The Overseas Grand Complication Openface is confirmed as a limited production, available with a matching titanium bracelet as well as two additional straps in alligator or rubber. For more details regarding the watch’s availability and price, visit Vacheron Constantin’s official website.
