The Overseas collection welcomes two new additions to their line up. Both come in white gold cases but offer two distinct iterations: one in a skeleton face and the other in a deep blue dial. The Overseas perpetual calendar ultra-thin skeleton comes with the Calibre 1120 QPSQ/1 movement which has been hollowed out, finished, and decorated in such a way to accentuate the functional beauty of the mechanism. The intricacies and craftsmanship of its meticulous finishings can be openly viewed from both the front and the back.

The second iteration of the Overseas perpetual calendar ultra-thin is presented with a translucent lacquered dial with facetted and luminescent gold hour markers and hands. This timepiece is driven by the emblematic Calibre 1120 QP/1 self-winding mechanical movement, beats at a frequency of 2.75 Hz, and has a power reserve of 40 hours.
Both these pieces come in an 18K white gold case that measures 41.5 mm in diameter and 8.1 mm thick. They have a soft iron casing ring to ensure good protection against magnetic fields. They have transparent case backs and are water resistant to 50 meters.
