Nivada encompassed other modern wristwatch innovations as well, creating waterproof and “rustless” watches that would stand up to the rigors of the outdoor adventures they were creating a watch for. 

In the 1930s Croton and Nivada Grenchen would form a strong partnership which allowed Nivada’s watches to be imported into the US without restrictions as long as they were sold under the Croton name, allowing Nivada Grenchen to grown they’re market tremendously, and for Croton to use the Nivada platform to continue assembling watches under their name.
