Grieb & Benzinger Blue Merit Watch Based On A. Lange & Söhne Tourbillon Hands-On

Back in 2014, the German team of Grieb & Benzinger that produces one-of-a-kind highly decorated watches debuted a lovely timepiece that began life as limited edition A. Lange & Söhne. Inside the Grieb & Benzinger Blue Merit watch is a movement produced by A. Lange & Söhne which has been taken out of its original Lange case and thoroughly modified.
