Making of the Blue Symphony by Grieb & Benzinger

This video presents you the "BLUE SYMPHONY" made by Grieb & Benzinger.

Solid 49 mm diameter platinum case with 130 grams platinum weight. Anti-reflective, domed sapphire crystal and flat sapphire crystal on the bottom. Crown made of solid platinum in inlaid with a blued-steel application. Screw-in sapphire crystal case back and hand-guilloché bezel. Navy blue alligator skin strap with platinum buckle. Hand-skeletonized Sterling silver dial decorated with an original Breguet frosted finish.

The 36-jewel movement with manual winding is based on an original Patek Philippe minute repeater movement, exclusively manufactured for the famous New York-based jeweller Tiffany around 1887. The compensation screw balance with blued Breguet hairspring beats at 18,000 semi-oscillations per hour.
In typical GRIEB & BENZINGER manner, the historical minute repeater movement with two polished steel hammers and two gongs has been awakened to enjoy a new life. The movement was completely disassembled, restored and modified to encompass a regulator indication, while the original transmission wheel has been replaced with a “mystery” wheel incorporating a specially manufactured glass inlay. All strike train parts, levers and springs were polished and beveled.

The unmistakable base plate was first hand-skeletonized and hand-guilloché before being coated with the blue platinum developed by GRIEB & BENZINGER. The visible spring barrel was skeletonized by hand. Every single bridge was hand guilloché, and coated with rhodium and rose gold. Even the wheels were guilloché, and the heads of all steel screws were polished by hand and classically tempered a cornflower blue over an open flame.
