Sizing

[JSolano305]

I'm about to buy my first Rolex next week from one of the trusted sellers here. Now I know the whole buying from AD experience includes sizing and what not. I would like to do that here in Miami but the prices at AD's are high. Anyways I've always resized my Movado's/Tag's myself as I've ever never bought them at a store. I know the Tags are harder to resize. So how are you guys resizing your Rolex...by yourself or you take your watch to a local jeweler? I have my own tools for that. But I've never tried it on a $5,000+ watch. Your feedbacks are appreciated. Thanx.
