NOTES: Nivada Grenchen is a Swiss watch company founded in 1879 in the town of Grenchen, Switzerland. Grenchen is the same town where several watch manufacturers were also established, including Breitling SA, ETA SA, Fortis, Eterna SA and Titoni Ltd. Very little information is available on these ultra-rare timepieces, which also makes them highly collectible.
One can also find in this earlier Chronomaster the prestigious movement: the Valjoux 23 (and subsequent 92), an icon in the history of the Swiss column-wheel chronograph movements from the mid twentieth century that was used by brands like Jaeger and Rolex for its robustness.
