Grieb & Benzinger Blue Sensation, 1889 Patek movement

The Blue Sensation is an extraordinary piece made in collaboration by Hermann Grieb and Jochen Benzinger. For it they chose a rare Patek Philippe split-second chronograph movement from 1889, originally made for Tiffany & Co.

Hermann Grieb rebuilt the movement to give it a régulateur display, and Jochen Benzinger finished the whole movement with guilloché, engraving and skeletonising, all by hand. More than 1,000 hours of craftsmanship went into it. The case is hand-made in platinum and weighs 265 g.
