Hi all, well what an interesting discussion to land on. Great to see you boys delving into the finer details of vintage Heuer. It can be a little cloudy but i promise you its an enlightening experience
Ok lets spit out some basic facts
There are NO ABSOLUTES when it comes to which insert the 1163/1163V/73463/73663 family of cases should wear ( this case series all use the same size bezel and insert ) !! We've seen so many exceptions over the years that its now accepted that you could choose your bezel style when you purchased your watch !!
Ok now lets look at some of the examples you guys have linked above.
The one Jens has linked wearing the MH bezel - there's a very high chance that the case is an 1163, not an 163V. Before the Viceroy run in 1972 the majority of 1163 black dials wore MH bezels ( please note - just because it has a MH bezel does not make it an absolute that its an 1163 case )
Hasse Varg's lovely NOS Viceroy - yes it has a lume dot at the top & this usually indicates that its one of the last run of the Viceroy ( usually serial number over 270xxx ).
We also often see these lume dot bezels on the 7734 & 7736 manual wind versions - but this makes sense as these manual winds were often produced at the same time as the last of the Viceroys.
Hope i've made it clearer for you guys - cheers - Darren
