So many beautiful time pieces here, just brings tears to my eyes! Hmmm, been collecting for some time now also, but my favorite pieces these days seem to be my Rolex Oyster Royalite, c. 1940s (my IWC Portofino is my daily wearer currently). On weekends, I enjoy my vintage WWII Rolex Skyrocket (shockproof, military dial) which I inherited from my father (along with his gold Air King). Otherwise, I’ll put on my vintage Tudor Oyster Air Lion (by Rolex), c. 1950 (jet-black honey comb dial). The Royalite, Skyrocket and Air Lion are all manual wind, smaller dials (boy’s size by today’s standard, but standard size for military pieces; then, the Portofino’s not much bigger, itself a mid-size and slim, as noted above. Though I like the Tool watches/larger cases also (I love that GMT, very nice; myself have a Submariner which reminds me is due for its service/overhaul), as they serve their purpose extremely well; but I’m just as likely to put on my Ebel Discovery or Raymond Weil Sport (on black rubber) when on vacation – or even a Hammy Khaki Chrono (has the 7750 workhorse, and also an excellent entry-level Swiss in response to those asking about entry levels, in my op.), as I really don’t want to attract undue attention when taking to the drink (aka the sea as in water sports) or otherwise in foreign lands, but could just be me (I’m just saying, that’s all … ). Ah, but if I were calculating cross winds/impending doom [as per the Breitling comment above, love it and your watch! (and in terms of collecting, the more complicated, the better they say)] ... Rolex: A bit of History: That said, I personally enjoy the fact that Rolex made watches in Canada during the war, selling them to CDN soldiers going overseas at PX military stores (note: Omega, Breitling and Rodania enjoyed contracts with the RCAF to make spec chronos through the 1950s, w/ Heuer making Flieger chronos for Germany (1935-40s), and Hamilton produced for the US military, suspending all civilian production for it, I believe). Rolex further supported Allied troops during WW2 in that, on being captured and losing their watches, POWs could order a Rolex on their “promise to pay” later (saying an officer's word was enough, though Hans Wilsdorf never collected, as I recall; whole thing boosted morale of the allies in turn). Just a bit of history on Rolex, which thought some people might like to know and which I’d share, in turn for all the wonderful pieces shared here. I'll see about getting a macro so that I can share some of mine with you, and thank you all again for sharing - I say again, wonderful pieces! tl/DR Rolex supported the allies, making watches in Canada for soldiers and gifting watches to POWs in the camps during WWII, being also the first to patent/bring many firsts to market, and I like them, too (history, along w. engineering quality).
