Nivada Grenchen Watch: Blue Automatic Autochron

Nivada Grenchen Autochron: automatic chronograph straight out of the 70s

The Nivada Grenchen Autochron Automatic Blue reinterprets a classic 1970s chronograph design in a modern and unconventional format. The blue dial with aged black sub-dials at 9 and 12 o'clock recalls the brand's vintage chronographs.

The case of the Autochron Blue is machined from 316L stainless steel with an alternation of polished and brushed surfaces. Its 38 mm diameter, 46.5 mm lug-to-lug length, and proportions faithful to the original model allow it to fit a wide variety of wrists. The double-domed sapphire crystal with anti-reflective coating effectively protects the dial while maintaining the aesthetic of vintage chronographs.

At the heart of the Nivada Grenchen Autochron Blue beats the famous ETA Valjoux 7750 automatic chronograph caliber. A true benchmark in the world of Swiss chronographs, this movement offers hour, minute, small second, chronograph, and date displays, as well as a 48-hour power reserve. Known for its robustness and ease of maintenance, it is one of the great classics of contemporary watchmaking.

Water-resistant to 200 meters, the Nivada Grenchen Autochron Blue is a genuine tool watch capable of accompanying its owner both in everyday life and during sporting activities. Available on a Flat Link steel bracelet or on various leather or Tropic rubber straps, this Autochron Blue offers an excellent balance between historical heritage and modern versatility.
