Nivada Grenchen Autochron Watch with Black Dial #77002A45

The revival of a rare vintage watch from the 70s
The new Autochron stands out for its elegant design, advanced technical features, and most notably, its one-of-a-kind face. Indeed, its dial is both striking and original, deserving a closer, deeper look to fully appreciate its exceptional beauty: a textured matte black background; two embossed sub-dials (minutes and seconds) in taupe with a hint of khaki, positioned in an inspired move at 12 and 9 o'clock. The tachymeter scale surrounding the dial adds a sophisticated tool watch touch. The pointed baton indices, enhanced with white Super-LumiNova® and a white or yellow dot, underscore the design's refinement. Similarly, the hands, also filled with yellow or white, echo the elegance. The bold white logo and the Art Deco typography contribute to a fascinating sense of visual depth.

Another notable element is the dial's origin, designed by Jean, one of the greatest dial makers in Switzerland. His exotic creations, such as the Omega Speedmaster Racing and the Heuer Skipper, are among the most sought-after in the watchmaking world. The Autochron incorporates these successful elements with a unique style that is sure to captivate discerning collectors.

To enhance wearability, the Autochron also features a push-button deployant clasp 18mm, offering optimal comfort and precision fit for the modern wearer.

At the heart of this watch beats the automatic Valjoux-7750-ETA movement, featuring a 42-hour power reserve and full functions: central hours, minutes, seconds, date, and more (see below). The 38mm 316L stainless steel case, with a thickness of 12.7 whitout glass (15.7 with glass), is protected by a domed sapphire crystal with an anti-reflective coating, ensuring both durability and clarity. The Chronosport also boasts a stunning fluted bidirectional rotating aluminum bezel, highlighted by a white or yellow dot at 12 o'clock that elegantly makes it pop. Water-resistant up to 200 meters, this watch is both a stylish and practical choice for aquatic activities.
