Hi all, Sorry for the elementary question but I am contemplating a purchase and was hoping to seek your collective wisdom. What is that blue stuff you sometimes see over the seahorse on a Speedy Pro caseback? I know Omega at one time used red paint as a way to see if a case back had been opened following a service. What is the likelihood that this is genuine, and not just made to look like it was factory serviced? The bracelet also appears to have been refinished. How much of a dealbreaker is that? Possible service hands..not sure. Will ask for more pics. Here are some for reference. Thanks for your help.
Protective caseback sticker applied before delivery, that apparently was never taken off. Not sure how it ended up just inside the hippocampus though
