Watch case

Solid 47 mm diameter platinum case with anti-reflective, domed sapphire crystal and a flat sapphire crystal on the case back. The crown pusher is made of solid platinum and guilloché. Screw-in sapphire crystal case back and hand-guilloché bezel. Hand-skeletonized Sterling silver dial with and overlapping displays and decorated with original Breguet frosted finish.


The 17-jewel movement is based on an historical monopusher chronograph movement from about 1926 with manual winding. The screw balance with blued Breguet spring beats at 18,000 semi-oscillations per hour.
In typical GRIEB & BENZINGER manner, the historical movement within this oeuvre has been awakened to enjoy a new life. The movement was completely disassembled, restored and decorated. The unmistakable blue base plate was first minutely hand-skeletonized to its barest minimum, hand-guilloché and finally coated with the blue platinum developed by GRIEB & BENZINGER.


The visible spring barrel was skeletonized by hand. Every single bridge was hand guilloché and plated with rhodium or rose gold. The balance cock was hand-engraved, rhodium-plated and then coated with rose gold. Even the wheels were guilloché, and the heads of all 34 steel screws were polished by hand and classically tempered a cornflower blue over an open flame.
