The scuffed bezel, where it says 20. Maybe some people don't mind that sort of thing but for me a total deal breaker. Pity, because otherwise it looks really nice.
These are very nice watches. I have a Mint one I picked up many years ago. Not sure of the value of yours but I just had mine valued for insurance purposes by a valuer and it came out at $3800 NZD, so about $2500USD.
Quite rare especially if you can get the divers kit with it which mine doesn't have.
What did you pay for yours or are you still considering?
