I just saw the 5140 in the flesh and I must say I'm enamoured. It has a more modern size of 37.2mm and has the perfect face.
Appreciate if owners of the 5140 or 3940 can comment on ownership experiences, eg reliability, fragility etc. I know the issue of investment brings scathing comments, but I'd just like to know what the chaps here think. When I hand it to my children in 30 years time, whether it'll have appreciated at least somewhat.
Thanks, David
