Hello, everyone. This time, I'd appreciate some help with an UG chronograph: an Uni-Compax, equipped with cal. 285. My main concern is its case: seller informs it's gold plated, with a SS caseback. The thing is: I've never seen any UG chrono with a gold-plated case! All of these ones seem to be either solid gold made, or SS. Doesn't help the fact that caseback bears no engravings (nor inside, neither outside) indicating serial number.
Dial seems ok. I was able to find at least one specimen showcasing a similar dial and similar hands. Movement seems too good to be true. My main concern is that it could be a franken. Seller is asking a really low price for this one (compared to what I've seen for sale online). Hence, my caveat. So, what say you, gentlemen?
