I'm very clumsy and my watches find every door knob in a room, in fact there's one in my house that I've been thinking about removing since I hit it constantly, so I fully expect the bezel to get scratched up. At the moment, it's too early to tell, only run into 2 door knobs, but I've been wearing titanium watches everyday for the last few years and haven't managed to dent any of them and only accumulated minor surface scratches, nothing that you can feel. If anything the polished sections on Ti seemed to show less scratches than the brushed unlike say the polished links on a Rolex that seem to scratch so easily you'd think they were platinum. Between the hardness of the material and the bezel being narrow and rounded I think it should develop maybe a nice patina of micro scratches that softens the look a bit but I think it will wear very well and not look beat up. Maybe that'll even make the polished hour spheres recessed in the bezel stand out more.
Out of curiosity how long did they tell you it will take to receive the watch? Mine took about 2 months for one that was already on order by the AD but not yet allocated....
