Not sure if anyone saw Darren’s beautiful bespoke piece he had Thomas Prescher create with a vintage Zenith movement in the AHCI section ( http://ahci.watchprosite.com/show-forumpost/fi-16/pi-5270788/ti-787468/s-0/ 
but I kinda like it and thought it’s a nice way to revive some great movements.
Or is it?
What do vintage collectors or collectors in general think of this?
I was kinda thinking of doing the same in a series of 3 for my 3 kids with what are considered (I read that is) to be 3 great vintage movements in the likes of:
Longines 13ZN

Omega 30T2RG

Zenith Cal 135

I did think of the Peseux 260 and the Valjoux (I think) VZSS movements but they seem to be really tough to find.
So is this considered a sacriledge in the vintage collecting world?
