Questions about Tudor ..

[Stonedcl]

I have been seeing a lot of nice Tudor watches you guys have been posting and I really like the one that looks like the daytona but has the date which is a big plus for me.. I live in the states (nj) and am thinking if I see one of the Tudors I might pick it up.. I know they do not have tudors in the states so if I was to get one would rolex fix \ maintain it? I also see some Tudors with a rolex crown and some with Tudor crown , when they they stop using a rolex crown?
Thank you
