GRIEB & BENZINGER Blue Sensation Split-Seconds Skeleton Regulator Chronograph in Solid Platinum

Germany based custom watch brand GRIEB & BENZINGER presents The Blue Sensation, a new unique piece in solid platinum based on a historical Patek Philippe split-seconds chronograph movement.

Hermann Grieb, watchmaking genius and one of the three partners of GRIEB & BENZINGER, has opened his horological treasure chest to charm out a valuable, historical, rare chronograph movement made in 1889 by Patek Philippe and delivered in 1890 to Tiffany.

The intense workmanship associated with the skeletonization and guilloché as well as the technical modifications of plates and bridges of this split-seconds chronograph took much more time and intense attention than all the minute repeaters worked on before it, however. Countless hours of detailed restoration, hand-skeletonization, hand-engraving, and guilloché were invested.

The fine guilloché work of the plates and bridges necessitated moving original drilled holes by less than one-twentieth of a millimeter, and the movement needed to be continuously reassembled, adjusted, disassembled, and reassembled in order to guarantee full functioning of the great number of levers and wheels despite their elaborate treatment.

The movement was disassembled more than 20 times before being reassembled in order to guarantee all functions, even those applying to the additional modifications.

A skeletonized dial with a rare Breguet frosted finish with overlapping displays in the characteristic GRIEB & BENZINGER style unequivocally shows the connoisseur the technical prowess needed to turn such a masterpiece into a regulator—a style for which the workshop is known. Additionally, it allows a view of the blue platinum coated base plate, a signature element of GRIEB & BENZINGER.

With The Blue Sensation, GRIEB & BENZINGER sensationally offers the only split-seconds skeletonized regulator chronograph on the market. This unique watch has a retail price of 197,500 euros (plus VAT).

With its 49 mm diameter, this unique timepiece is not only a design statement on the wrist, with a full weight of more than 150 grams, it is once again the heaviest platinum watch in the world.
