If you take away the "superficial similarities", what are you left with? Looking at the cvstos beyond its stylistic similarities (or blatant knocking off- w/e you feel it should be described as), I dont see a particularly compelling watch. I dont know enough about the company and its movements, but are you basically left with a franck muller? better? worse? Why do they exist? can they justify their existance? Well, if they find a market then they will continue to be around- thats the best you can ask for. I think, given the economy we are entering into, this type of watch will have trouble, and many of the people that would be interested in this type of watch are already in trouble financially.
Perhaps the argument supporting it would be that entry level RMs are completely overpriced and not worth it, but their design is great, so why dont I just buy a cvstos?
