I've always wanted one of these, but I've never seen one in person. I suppose this would be considered my "grail" watch, since I've never really felt I needed one badly enough to actively pursue the purchase, yet it constantly calls to me. I believe they used the Cal. 321 movement. I know they are a bit small-ish, by today's standards, at around 36mm. I already have a 34mm 1961 Seamaster that typically only gets worn on dressier occasions, when I want something slim and sleek to disappear easily under my cuff. I would want to wear this anytime, though. Not having seen one up close, I don't want to build the watch up in my mind to be something I'm disappointed in when I actually get to hold one. So, I wondered if any WUS members have some owner reviews or opinions to share on one of these. Is it one you'll never give up, or was it a catch and release...and why? TIA.
