GREUBEL FORSEY
Double Balancier Convexe
This newest addition to the Convexe series finds the watchmaker ’ s existing Double Balancier movement ( in its latest 2016 iteration ) presented in a convex titanium case with a dramatic curved layout displaying the caliber ’ s openworked gears , wheels and bridges .
Within the undulating bezel , which Greubel Forsey first presented in 2019 , we see the watch ’ s gear train in all its multi-level , highly finished splendor just below a semicircular black-treated titanium bridge .
Flanking each corner are the watch ’ s namesake two balance wheels , each inclined at 30 ° and separated by a constant spherical differential that ‘ calculates ’ their average timing rate .
Greubel Forsey explains that it constructs each hand for this watch ( and for many watches in its collection ) with individual geometry , finish and color . Thus , the hour hand and the minute hand are curved and filled with SuperLuminova to complement the hour indexes .
The small seconds hand is polished and blued steel , as is the four-minute hand ( set between the two balances ) that shows the rotational speed of the spherical differential . Finally , the power reserve hand is polished , openworked and tipped with red .
Greubel Forsey offers the new Double Balancier Convexe on either a textured rubber strap or titanium bracelet . The manufacturer will make twenty-two per year between 2022 and 2024 for a total of sixty-six pieces overall .
