AUTOCHRON ORANGE AUTOMATIC
77004A10
The most mechanical expression of the new Autochron. A vivid orange-gradient dial, 120-click aluminum bezel and compact 38 mm steel case are driven by the legendary ETA Valjoux 7750 automatic chronograph movement.
Racing energy, mechanical substance and unmistakable 1970s character.
Born from one of Nivada Grenchen's rarest late-1970s experiments, the Autochron returns with a new generation that preserves the original's unconventional sports-chronograph character while sharpening it for today. The Autochron Automatic Orange places the mechanical movement at the center of that revival. Its matte black dial transitions into a vivid orange gradient, framed by warm beige chronograph counters and applied luminous indexes. Around it sits the new 37 mm aluminum click bezel with 120 positive positions, giving the Autochron a more tactile and functional personality. The 38 mm vertically brushed 316L stainless-steel case, double-domed sapphire crystal and 20 ATM water resistance keep the proportions vintage while delivering contemporary robustness. Inside is the ETA Valjoux 7750 automatic chronograph with date, beating at 28,800 vibrations per hour according to the supplied product specification. The result is the purest mechanical version of the 2026 Autochron: bold on the dial, compact on the wrist and unmistakably rooted in racing culture. Available on the Autochron stainless-steel bracelet, black racing strap or orange Tropic rubber strap.
