This one, the Senator Diary and the Panomatik Counter XL are models that are unique, as far as I know. I would not say that they are niche products but more products that appeal to a die hard watch fan who loves
mechanics and loves adjusting, correcting and "playing" in general with a mechanical watch.
This particular model needs a fair amount of time to understand but I am sure it is great pleasure using it.
Credits to GO that a complex watch like this is still keeping the GO design DNA.
