Reasonable to Request to See Rolex Internals before Making Online Purchase?

[westsiderkg]

Is it unreasonable to ask, in a long distance online transaction, for the seller (i.e. grey market dealer) to remove the case back (all of 1 minute) on a new watch and send a photo of the Rolex internals if you have already agreed upon a price and are 100% ready to make the purchase upon verification? Sorry if I am asking too much (don't think I am), its just I want to be certain in my mind (regardless of how many good sales a dealer has) before shelling over funds. Am I off base or does this sound reasonable? I am not a risk taker. Thoughts? Is there a better way of going about this?
