For the last year, the Kalpa XL Hebdomadaire Anniversaire has been creating a sensation, thanks to a steel middle that houses a movement made from solid gold. In its wake, this new creation has added another chapter to the history of a collection that knows how to maintain suspense.

The Kalpa XL Hebdomadaire is driven by the PF 110 hand-wound movement, with a tonneau shape that perfectly marries the contours of its housing. This proprietary double-barrel movement ensures an 8-day power reserve and features a patented display system. Its powerful aesthetic owes much of its impact to the repeated semi-circular forms of the bridges. Their shape is based on a cutting technique which allows for greater complexity and more internal angles. The "Côtes de Genève" decoration, the swan-neck featured on the balance, and the hand-bevelled bridges are amongst the subtle touches that demonstrate the high standards demanded by the Manufacture.

The rose gold case contains a silvered yellow 12-sector flinqué effect dial. The materials and colours of this piece were selected to create a synergy, to the most beautiful effect. Beyond its obvious opulence, the rose gold of the case suffuses the watch face with an amber glow, giving the Kalpa XL Hebdomadaire a unique colour scheme.

To ensure the ideal proportions so dear to Michel Parmigiani, the indicators at the top and bottom of the dial are perfectly balanced. While the identity of the piece lies in its tonneau shape, this quest for harmony creates a striking aesthetic. The delicate contemporary numerals, the solid gold indices and the original alignment of the numerals around the small seconds dial ensure perfect readability and complete this vibrant dial.

Ergonomic, with a large power reserve for optimal practicality, the Kalpa XL Hebdomadaire is both assertive and refined in its appeal.
