SIHH 2019: Vacheron Constantin Overseas Tourbillon

Paul Altieri

The new Vacheron Constantin Overseas Tourbillon (reference 6000V/110A-B544) marks the first time a tourbillon complication has ever been fitted to a watch in the Overseas collection. Powered by the ultra-thin Caliber 2160 movement, the new Vacheron Constantin Overseas Tourbillon offers users an 80-hour power reserve, and features a peripheral rotor for an unobstructed view of the intricate tourbillon complication, which sits center-stage, visible through both sides of the watch.

Vacheron Constantin Overseas Tourbillon

The ultra-thin Caliber 2160 movement, which first made an appearance in 2018, is constructed from 188 individual components and measures just 5.65 mm thick – a feat that is largely made possible by its peripherally-mounted oscillation weight, which happens to be craft from solid 22k gold. The bar of the tourbillon carriage is entirely bevelled by hand – a task that requires around 12 hours just to complete this single component alone. The new Overseas Tourbillon displays the hours and minutes on its center-mounted hands, while the tourbillon complication, which is located at 6 o’clock location, serves as a running-seconds indicator.

Rather than casing the watch in a precious metal such as gold or platinum, Vacheron Constantin has chosen stainless steel for the construction of their new Overseas Tourbillon. The case and bracelet follow the same design language as other pieces in the Overseas collection, while a striking blue lacquered dial with a circular cut-out offers full a view of Vacheron Constantin’s Maltese Cross-shaped tourbillon. Like the new Overseas Perpetual Calendar watches that were also introduced at SIHH 2019, two sets of blue-colored straps (alligator leather and rubber) will be included with the watch (along with a matching stainless steel bracelet), and all of these can easily be swapped in and out via Vacheron Constantin’s tool-free strap changing system.
