Authenticating Railmaster grey import without removing caseback

Hi

Am awaiting delivery from reputable Japanese dealer of new old stock Railmaster. Purchased through Chrono24 Buyer Protection but how can I be assured of authenticity? It should come with original papers and box, serial number etc. The case may be easily authenticated but how do I know that the movement hasn’t been substituted without taking the back off. Really don’t want to do that and would it be really necessary?
Thanks
Jeremy

unless it has a clear caseback, you don't/ can't.

Buy the seller. If he has many sales, and good feedback, and if the watch comes with all documentation (3 red cards) you are not likely to get a watch where the movement has been swapped. If he is a 'reputable' dealer you don't have much to worry about. There isn't much upside for a good seller to open up an authentic watch and swap out the movement for a cheap, generic unit.

Yes - does feel a bit over the top in the circumstances. Might only take a look at the movement if not all paperwork present, not running to METAS etc. Might have to expect to take a day or two to settle I guess if it’s been sitting on a shelf for best part of a year.
Very helpful - thanks
