37 vs 41 Popularity?

[dmash]

Is the Royal Oak popularity still like that as of 4-5 years ago where the 37 15550ST has a much smaller following than the 41 15510ST? I’m pondering going in to pitch myself for a silver ROC 41 and then a matching silver RO 37 for the wife. Is this a reasonable play or are the 37’s hard to obtain as well and it doesn’t really give me an advantage? Actually not technically wanting until next year after the 50th rotors are discontinued anyways, just seeking a collection date of sometime in 2023.

Any help would be appreciated!
