Right when I got it I had it looked over, the did a full cleaning on the bracelet and inspected the movement but it was in good shape so all they really did to the head was pressure test it.
The plexi has some character, and I like it like that. Ideally, I'll never have it polished and it just remains as is, it's nicely worn and in good shape. My only fear is if I wear it the lugs will incur more damage, I'm fine with how they are I just don't want them to get worse. In some pics it might look like a shadow but it's actually a chunk of the lug that is worn away, as it is now (aesthetically) it doesn't bother me, but I worry if it gets worse that the case will be ruined. I just don't know if this type of wear happens slowly or rather sudden.
