Nivada Grenchen 77003A45 Autochron Blue Dial Automatic 38mm

A true revival of a 70s prototype, the Autochron Blue Petroleum is a vintage-inspired automatic Autochron with a modern twist. Its matte petroleum blue dial features a granulated texture, creating a striking visual effect alongside the embossed black sub-dials. The dial is enhanced with Super-Luminova-coated baton indices and hands, ensuring excellent readability.

Powered by the Valjoux 7750-ETA automatic movement, this timepiece delivers 42 hours of power reserve and features a tachymeter scale for speed measurement. The 38mm stainless steel case is topped with a domed sapphire crystal and features a bidirectional fluted rotating bezel with a yellow dot accent at 12 o'clock.

Water-resistant up to 200 meters (20 ATM), the Autochron Blue Petroleum is available with Tropic rubber, leather, and steel straps, offering versatility for any occasion.
