Speedmaster 125 - a question please

Hi, I’m just about to buy a Speedmaster 125, and this example was serviced a few years ago, been told it’s running well, and whilst not perfect at all seems pretty good. Case has a few knocks and bruises but it’s 50 years old after all.

Question I have is the dial. The lume is very brown and aged, and I havent really seem many if any like this. The dial also apparently has spotting. What do you knowledgeable folk think, does it look ok? What does the dial spotting indicate, possible water ingress?

Thanks in advance

Thank you for your reply. I’m happy the movement is ok as it was serviced a few years back and all old parts are being supplied with it. So I may just need a nos dial to replace it with

Or "whiten" the lume to match the hands.
