In 2009, after extensive research on multiple regulators at Greubel Forsey’s EWT Laboratory—Experimental Watch Technology—, the inclined Double Balancier was introduced as a prototype at Baselworld. The two inclined regulating organs —then positioned on top of each other— now occupy distinct and separate three-dimensional spaces. Released for the first time at the SIHH 2016 in white gold, then in rose gold at the SIHH 2018, now comes this amazing Greubel Forsey Double Balancier in the most complex case material possible.
