Trust me, I am really not a fan of the bigger watches, the 15400 is way too large IMO even for bigger wrists. I think even the 15300 or 15202 is very large but I have been considering them solely for the reason that they are good franken bases. The 15450 is simply too new for that and would end up being some fantasy model (because I doubt I could find a non-vintage dial in blue or black at a decent price).
I do not share the opinion that the 15450 is a lady's watch at all btw, I was simply shocked that they labeled it as such in a respectable german watch magazine and it kind of offended me in a way because I was considering the even smaller 14790.
My main watch will be a 5-digit (kinda vintage) Daydate franken that has a diameter of 36mm but wears a bit larger.
Can anyone comment on the thickness compared to genuine regarding the 15450 ? This seems to be a problem for all the royal oak replicas.
If thickness is your concern than 15400 is the closest match, since its just a 1mm compared to gen. But 15450 is much more if not mistaken.
Reading from the above comments, I seriously do not see this case size as an issue. Perhaps you may not be comfortable with larger watches, i've started up with a Panerai as my first rep, without even trying the gen on my small 6 1/4 wrist. At first I felt extremely uncomfortable, thinking it was way too big for my wrist, but over the years i've learned to cherish bigger watches and have a couple of 42mm divers, 44mm ROOs. My recent procurement was the 15400, and during my much earlier phase into replica I really couldnt understand why people were all dying to own one of these. But I got to say the 15400 is one of the greatest off the shelves rep ive bought so far. I know its not perfect, the dial is farfetched but it just captures so much attention compared to the rest.
A few months ago, I bought a franken Paul Newman Rolex Daytona from a member, the case has been reshaped like gen to 37.8mm, and even with the black contrast bezel which is suppose to make the watch look oversized, I felt it was very small on my wrist. Not sure why, perhaps I wasn't used to it.
Anyways, just letting you know from my experience.
By the end of the day, im looking to sell most of my reps and only keeping the frankens.
