I’d value the pulsometer at least equal to a DoN, if not significantly more. Say 100-150% the value of a comparable DoN.
If proved to be vintage, the telemeter/decimal one would be say 80-100% the value of a comparable DoN bezel.
A month ago, a telemeter bezel (in miles), in a really good condition, has been sold for almost 3k chf. I'm not even sure that it's a vintage one (I think it was a flat 3).
A vintage decimal in average condition has been sold for 1600 chf.
Was the decimal bezel the one displayed on ricardo.ch ?
