It’s a good point for concern, but one that you might assure yourself of by taking another critical look at the TF, again. I don't have a rubber bezel Breitling, but I do have a Mido with a somewhat similar setup. It’s more of a very hard plasticized material rather than rubber in my case. Stands up to wear very nicely. True, it is the reverse of the Breitling in that the numbers are metal and the bezel is the synthetic material. In this case it may be an all in one and not separated, a little difficult to tell.
If the TF numbers are a little spongy to the feel, then perhaps that might be an even better arrangement as bouncing off or glancing may be less damaging than something harder. If the projection of the numbers is low, they are less likely to get caught or snagged. Higher profiles might be levered out much more easily.
Just some thoughts.
You've set my mind at rest about it, so all I need to do now is get that deal!
Yeah I don't do too many wrist shots (or photos in general) as I don't share everything publically. But if I manage to land one of these, then rest assured I will be posting some pics...... if for no other reason that to prove I've "gone over to the Buck side" (to quote Al)!
