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 subdials at 9 and 12 o'clock recalls the brand's vintage chronographs.

The Autochron Blue's case is crafted from 316L stainless steel with alternating polished and brushed surfaces. Its diameter of 38 mm, lug-to-lug length of 46.5 mm, and proportions faithful to the original model make it suitable for 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 renowned ETA Valjoux 7750 automatic chronograph caliber. A true benchmark in the world of Swiss chronographs, this movement offers hour, minute, small seconds, chronograph, and date displays, along with 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 true tool watch capable of accompanying its owner both in daily life and during sports activities. Available with a Flat Link steel bracelet or various leather and Tropic rubber straps, this Autochron Blue offers an excellent balance between historical heritage and modern versatility.
