My collection is mostly divers, but I do have a few aviation models mixed in too. I'm not sure where the Panerai fit in because they are of dive heritage, but don't really meet the criteria that most think a diver needs, so I will just call them a socialite group.
Here's my current collection in no real order:
PAM090
PAM111
Rolex GMT II
Omega PO (biggin')
Omega X-33 (2nd gen)
Oris Carlos Coste
Sinn U2
CX Swiss Military 12,000'
Bathys Benthic (S-B-R)
Bathys 100 Fathoms (black)
Breitling Aerospace
Casio Pro Trek (PRG80L) (high end stuff)
Citizen Ti EcoZilla
Aninimo Polluce (black & bronze)
