Description

The present reference is the Vacheron Constantin Patrimony Contemporaine Ultra-Thin Calibre 1731 ref. 30110/000R-9793, a minute-repeating wristwatch unveiled in 2013, distinguished by an acoustic architecture developed to give its chime exceptional clarity and resonance.

At the heart of the watch is Calibre 1731, whose striking mechanism reflects a carefully considered relationship between movement and case. Rather than sitting side by side, the gongs are stacked and connected directly to the case middle to amplify their sound. Airflow around the mechanism is also carefully managed, while the case’s joint-free construction promotes direct metal-to-metal interaction, enhancing acoustic transmission. A flying governor regulates the cadence of the hammer strikes, ensuring a measured delivery of the hours, quarters, and minutes.

Each repeater requires several months of assembly and adjustment, with its individual voice shaped by the master watchmaker before undergoing further assessment by the manufacture’s striking-mechanism specialists. Particular attention is paid to the balance between the low and high notes. Testing takes place at 4:49, when four hour strikes, three double quarter strikes, and four minute strikes allow the rhythm and transitions to be closely evaluated.

The ref. 30110/000R-9793 thus offers a particularly intimate expression of haute horlogerie: a timepiece whose defining craftsmanship is not merely seen, but heard.
