I've never really thought about it to be honest, as in i've never told myself to stick to certain gen budget etc.
That said i get what you mean, most of watches are ones that people wouldn't question me on the authenticity of it in the position i'm in at 22, 8k hublots, 6k rolex's etc, that said i recently bought a daydate and as amazing and i really mean it the reps of these are really nice, i just didn't feel comfortable wearing it and sold it on as i want to enjoy wearing watches not want to hide it everytime someone takes a look!
I guess it's also dependent on the brand of the watch, for example i didn't feel comfortable wearing a 30-40k rolex rep but yet i have an a.lange & sohne datograph that is one of my favourites and i'm always comfortable in that and they're 50k or so? but noone has a clue, it looks like an expensive watch but the vast majority of people my age wouldn't know ALS!
I've got the new AP rubberclad on the way - my first AP aswell! - and to be honest i hadn't realised the rrp of the gen's of these, i think i will feel fine after i've had the cyclops modded etc but we'll see. They're becoming a lot more popular in UK recently so more and more people know about them so i'm slightly worried i might find it uncomfortable to wear.
That said the RGRC is one of my grail watches so i'm sure it'll be fine.. but then so was a rolex DD.
