Thunderbolt

A grade 5 titanium case brushed, bead-blasted, and coated in black DLC creates contrast and sheen against the bright orange aluminum part-line and the Fastbacks signature cushion shape matte black ceramic bezel. DLC coated titanium push-pieces enveloped in grade 5 titanium crown guards extend the Fastback’s high-tech purposefulness by providing large start, stop, and reset contact points to activate the customized Dubois Dépraz DD-268 skeletonized chronograph module.

A unique two-piece crown design in full grade 5 titanium with a DLC coated center hub and three-spoke claw design sends power to the mighty ETA 2892-A2 automatic caliber via Dubois Dépraz’ patented Stem Transmission System (STS), providing a balanced external pusher crown alignment. To ensure optimal nighttime usability, all chronograph indications, including hands, counter scales, and tachymeter, are treated in X1 Super-LumiNova. Our italic Gorilla logo inspired the Thunderbolt name. Consequently, the luminescent-filled, bathtub-applied logo sits riveted against a lightning bolt design background.

The open-worked dial of the Fastback Thunderbolt chronograph is designed to evoke the flamboyant spirit of motorsport with its luminescent Arabic numerals and the recognizable powder blue and orange color combination, and yet not obstruct the skeletonized movement’s intricate beauty or compromise on time measurement readability, even in dark conditions.

The Fastback Thunderbolt chronograph proudly celebrates the Gorilla x Dubois Dépraz collaboration by engraving their signature on the movement “couvre” of the 99 numbered pieces of this mechanical time-measuring instrument born in the cradle of watchmaking.

The Thunderbolt is a Limited Edition of 99 pieces.
