In my continuing pursuit of a Speedmaster 3520.50, Mark 40, one of the problems I come across is in finding that most listings do not provide a view of the movement. On enquring some say they they don't have the equipment or ability to open the case, even though they have sold hundreds of watches! I do ask for an accuracy figure but from what I've learnt, essentially on here, is that this isn't a definitive indicator of the health of the movement? Cutting through my usual waffle what I'm asking is, is it reasonable to ask for an image of the movement and should I exclude those listings without? Grateful as ever, folks, for any advice, and to OF.
