I've managed to acquire 2 bezels for my PAM 25H. There are many differences between them, which requires an explanation. What do you think?

-Both bezels are legit, but different generations
-One of them is "aftermarket", the other is legit
-They are both wrong...not OEM

I didn't do this as a poll because I want to know your reasoning. I don't just want an answer to my question, I really would like to build on my knowledge of this watch that I love. Thank you for taking time to help me













Additional info:
-The lume pip glows equally on both bezels. It's about the same brightness as the numbers on the dial.
-Neither bezel is magnetic. The rivets are not magnetic on either bezel
-Bezel 'B' has a little extra cut-out near the divet where the nylon bezel ring attaches

Yeah, I was looking for insight into why they are different.

Is one of them "aftermarket"? Are they from different generations or models of subs?

just on the bezel # B the numerals were " turned ", maybe for an estethycal reason

Any idea why there are so many differences?

-'A' has shiny rivets that appear to have machine-mark swirlies
-'B' has flat rivets that aren't shiny

-'A' has taller rivets than 'B'

-The '45' on the 'A' bezel has a '4' with a flat top.
-The '45' on the 'B' bezel has a '4' that is pointy on top.

-'A' has the numbers packed more closely. There is little space between the '3' and '0' in '30'
-'B' has a lot of space between digits. There is a gap between the '3' and '0' in '30'.

I've been scrubbing the net for images to try to put each bezel with a particular model and generation and I'm having a heck of a time.

Anyone able to match these to specific version of sub?

Much thanks!
