Over the years, we have seen a handful of different photos showing Jo Siffert wearing the watch you show -- a white dialed Autavia Ref 1163, but with the MH bezel. We have seen these photos, but I can't recall anyone offering an explanation (although perhaps we have discussed it previously . . . perhaps the Search function on this forum or Google could assist).

Of course, we have also seen Jo Siffert wearing a Monaco and a black-dialed Autavia.

One thing to keep in mind is that Siffert was selling Heuer chronographs to the drivers, and anyone else who would buy them, so it is not surprising that he switched around on his own wrist, every once in a while. Also, we have seen different drivers, swapping watches with each other.

Well-spotted and thanks for sharing!!
