In addition to its stirring aesthetic appeal, this stunning High Jewellery model is driven by a mechanical self-winding GP330-00900 movement, designed, developed and produced by Manufacture Girard-Perregaux in accordance with the finest Swiss watchmaking traditions. This 218-part movement with its 46-hour power reserve is also distinguished by its splendid finishing. The bridges and the mainplate are straight-grained on the sides and on the rounded parts of the ridges. They are then chamfered, circular-grained and adorned with a Côtes de Genève pattern, while the gold oscillating weight is graced with a “GP” tapestry motif. The transparent case-back provides a chance to admire the meticulous craftsmanship that enhances the power of this exceptional model.
