Warning: May Contain Hornets 
As a watch ignoramus, I need to ask a question. I suspect it might be "sensitive" to some, so all the more reason:
How big is too big? I mean, the obvious answer is "whatever you like" and "depends how it looks on the wrist", etc. But I sense there is a stronger orthodoxy than that among the real wit-stolen watch lovers. The ones who spend more than they can afford and, well, "collect", in their own words. Well, you guys no who you are. The Watch Appreciation Thread Royalty!
It seems to me that way back in the day, a man's watch was about 33-36mm. Now 36 is considered small, 33 is for girls, and something like 38-40 becoming the "moderate". Meanwhile 40-42 is just a bit obvious, but not excessive, and mainstream makers are offering 45+ in established models. And of course, the girls no longer wear girl watches all the time - small and medium "man" watches are now their thing.
The impression I get is that for those who have serious collections, or a decade or two of active collecting and learning, the big monsters are considered inherently bad form. Would that be fair to say? As well as all you Patek-flashing high rollers out there, I'd be interested to hear from Mr Stitch, who as both a dealer and Panerai lover, might have a different slant.
So come on, spit it out: are big watches silly, and where do you personally draw the line?

(One of the reasons I ask is that I tried the above watch on yesterday, while taking my old (35mm!) Omega for repair: this felt like a real blunt instrument. It also appealed to my inbuilt affinity with excess, and didnt' look entirely stupid against my vast cow-eating body. But...is it just wrong?)
