There are a few Cellinis that look pretty good. However, even as a big Rolex fan, I've never had a desire to own one. For what they cost there have always been watches from other brands I'd rather own. Rolex produces great sports watches and all purpose watches, but IMHO dress watches are not an area in which they excel.
@no frills I get you. It's not my idea of beautiful exactly, and some of them I just find plain ugly, while at that price point it would be bordering on insane. But, as you said, putting one on the wrist does help you at least "get it".
More to the point, they are bumping right up against the likes of JLC, Piaget, Cartier, GO, Blancpain (choose your flavour) for an interesting precious metal dress watch. I don't think that's a choice from which anyone other than the most ardent Rolex brand-whore would say "I'll take the Cellini, please".
The RM watches just don't do anything for me at all. I get the engineering that goes into them, but I find them so ugly that none of them would ever make my dream wish list. I see them as a brand that has gone out of their way to be different and stand apart from others, which is fine, however different doesn't translate to better. This is another brand that when I see what they cost, there are lots of other watches I would rather own for the same money or less.
Agree completely with your assessment of Cellinis.
