Following in your footsteps, here are my "pride and joy" watches that will always stay in the collection, others will come and go, but these are permanent..
(especially this one - this is probably the most comfortable and accurate (for a mechanical) watch I own, good for juts about any occasion, I call it the "stealth Rolex" as it has a lot less flash that most of the other Rolex models.)
Ref 114270, Explorer I, Caliber 3130, 31 J automatic, nice bit of history with the Explorer I, too. Tenzing Norgay wore the orginal model, on the first ascent of Everest. That model, the ref 6350, is the grandaddy of this ref 114270. Picked this one up new, in 2006.


1940's Omega 30T2 manual wind - from the "International" line:

Another Omega, F300, ESA 9164 tuning fork movement:

Another Omega - bumper auto Seamaster:

And another hummer, Logines Ultronic, ESA 9164 movement:

Yet another hummer Accutron 218 RR (1973) in a 14K gold case.
