Of Citizen’s chronograph range, the model most likely to have a badly worn bezel is the 67-9054. The design leaves the bezel exposed to wear and tear, so finding one in good condition is quite a challenge.  As a result I very rarely wear this one!:

With a solid link bracelet and a chunky case, this model feels good – it’s a shame that the bezel is so vulnerable – it’s hard to see in the pic, but the bezel sits slightly proud of the case so the edges are particularly exposed 😦
