The Overseas, first debuting in 1996, is Vacheron Constantin’s household sports watch line. Currently in its third generation, the collection is diverse and well-developed, showcasing pieces with a wide range of complications and aesthetic nuances. One of its most beautiful and complicated offerings is the Overseas Perpetual Calendar Ultra-Thin.

Driving the Overseas Perpetual Calendar Ultra-Thin is the 276-part, 36-jewel Calibre 1120QP/1, developed and manufactured in-house by Vacheron Constantin. The self-winding movement has a power reserve of 40 hours and operates at a lazy 2.75 Hz beat rate. The low-ish power reserve and languid oscillation of the balance wheel (to save energy) is common in perpetual calendar watches as the complication is power hungry. This is even more the case in thin perpetual calendar timepieces such as the Overseas Perpetual Calendar Ultra-Thin where the mainspring barrel is restricted in size. The movement is, impressively, only 4.05 mm thick.

As to be expected from Vacheron Constantin, the Calibre 1120QP/1 – certified with the Hallmark of Geneva – is finely finished. Decorations such as Geneva waves, perlage, black polishing, and chamfering are done by hand and can be seen through the exhibition case back. The most eye-catching part of the movement is the 22k gold oscillating weight, adorned with a wind rose and multiple types of contrasting finishes.
