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.
Croton was the US name found on Nivada Grenchen watches.
