Benzinger ONE, Patek Philippe for Tiffany & Co.: skeleton and dial

Atelier · · by Christian Bissener

This is the latest step in the Benzinger ONE – Patek Philippe for Tiffany & Co. project, following the first fitting of the naked movement, the design, the first parts finished with guilloché and engraving and the guilloché on the main plate. The main plate is now finished, all parts have been cut out by hand to form the skeleton, and the dial is complete apart from its Breguet frost finish.

Main plate and bridge

The first two pictures show the main plate and its bridge with hand-made guilloché, and the skeleton cut by hand. The skeleton is a crucial part of the work, because the smallest mistake can ruin everything. In each project the guilloché and engraving are done first and the skeletonising afterwards.

Fitted plate and dial

Next, the main plate fitted with its bridge at 3 o’clock, and the dial, whose open design gives a view of the movement. Its Patek cross is entirely engraved and skeletonised by hand. The Breguet frost finish of the dial and the colours of the plate and bridges will follow later. The last photo shows the naked movement during the first fitting into the case, which gives a better idea of the individual parts.
