I dont know about repaustrias watch, but the pics pt provided look legit to me. maybe it was because he ordered a Datejust and not a Submariner? Subs have a different bracelet and are overall the more popular watch, I would say.
Also as far as I know, not even genuine rolexes have solid gold crowns, because that would be total [censored] for a crown. Gold is too soft for a crown! The threads would stripe pretty quickly.
As for the bezel, I dont know, I have no idea how they are constructed or anything like that.
Maybe a solid gold bracelet was just put on a regular TT datejust? Have no idea, but PT should comment on this.
