In witness of their ongoing friendship, for the second year running British watchmaker Peter Speake and Geneva Manufactory Frederique Constant have just unveiled a limited edition born from their partnership. The exceptional piece, destined for demanding collectors, features a sophisticated complication: the perpetual calendar.

The perpetual calendar is one of the most prestigious complications in Fine Watchmaking, allowing all calendar information to be read off in a single glance. It also takes into account the various changes during and between years; no adjustment is required between months with 30 or 31 days, or for February in leap years.

This rare timepiece, of which just 35 will be made, comes in a full black style encompassing the case, strap, and openwork dial, all the better to highlight the inner workings of the FC-775 manufacture movement. Featuring satin-polished components, blued screws and a sapphire crystal caseback, fine Geneva workmanship accompanies British audacity here in a watch that's as rare as it's contemporary - the very essence of High Watchmaking.
