I know there was an earlier thread on this, and I also was not sure about the tachy bezel on the 11063 model but really I am not so sure after seeing this watch. The photos are really clear of the bezel and I think that two things are apparent:
1) the bezel insert fit looks absolutely perfect; I'm not sure this would be possible if the insert was from a 11630. I'll do some accurate measurements tonite but my instinct is that the 11630 bezel insert was wider than the 11063.
2) the finish of the bezel insert looks semi-gloss, almost matte. The finish of the 11063 MH bezel inserts is much less glossy than earlier Heuers.

So...I am begining to think that this tachy version is correct and actually I bid on this thing (but not enough).
