There are some issues with this, but an interesting case!
You're right that the markers aren't solid gold; to the best of my knowledge this is the case with all watches with exception of those with solid gold dials.
My main worry with this one is the red gold case - I would expect matching gold dial furniture, not yellow gold as here. Had it been a steel case it wouldn't be as clear cut, but my educated guess is that the dial and possibly also the movement came from a different watch.
