Is that most of the dealers that I have spoken to for both used and new pieces say that greatest demand is for 40mm...(amongst normal watch buying public, probably not those who frequent internet forums!)
even Panerai CEO said in an interview most important bread and butter watch is PAM 50.
Ironically, the rarest models are 40mm...
Here's wishing for 1950 in 40mm....but if I hold breath any longer, I'll look like a smurf
