Well, since you asked, here's my 'solid-caseback' mech PAM rep list in order of preference:
- "Old-school" 1B-L (PAM001B L-dial) - the whole rep is just awesome, caseback is close to perfect, with re-lume and cannon pin fix you get one of the closest Pam reps available.
- PAM061D, in Titanium (brown sausage dial), the whole watch is unbelieveble, the caseback looks like it was 'removed' from the gen - simply perfect!
- DSN 5218-201/A (with either his own or standard rep's Logo caseback)
- "Logo 5 G" (PAM005G)...G-series caseback is spot on, standard rep dial has some minor issues though. DSN dial as an alternative.
- "Logo Base G" (PAM000G)...again G-series caseback is great, slightly wrong OP number though, dial is nice, logo close to 1:1 but letter 'R' is wrong shape/font.
...my 2 cents...
