I'de just say, ask for the reference number. Be aware that some of them need a special tool for openning which can be a pain when you just need to regulate it.
Because they are front-loaders, with no good way to release the movement from the case, at service etc, they often has damages to the dial. Especially at 12 o'clock
This makes no sense to me...if there is a fault that is causing damage to dials, it's from idiot "watchmakers" who don't know how to properly remove the movement from the case...
What I should have said also, is that I have seen quite many Seamaster Cosmic with damaged dials, to draw the conclusion that the movement is not easy to remove (without a proper tool).
