...had some interesting divers during that 60s time period in which we saw the rise of so many classics from other brands such as Longines, JLC, etc.
The Felca model I have seen and liked is a compressor cased "Seascoper" I think (I may have the model name wrong).
I just saw a cool Nivada diver the other day. Not sure of the model name, but it was an honest, handsome example of a '60s dive watch.
