I think I saw a post somewhere saying that if Omega re released the De Ville as a 38/40 mm that it would be extremely popular. It'd still be an especially expensive watch to me, but that aside, the 1963 Sea Master below in a 38 might be my favorite watch I'd have seen in months of looking at this thread, chrono24 and WatchUSeek threads. I like the simplicity and see at as elegantly refined where someone else might see it as boring. The Intramatic might have worked as a more easily attainable substitute if only it were 3 handed.
42mm as a dress watch especially feels a little large to me. 34mm today, especially on a bit of a bigger guy and I'm afraid it would read as I were wearing a woman's watch, otherwise I'd go grab an $800 vintage Omega tomorrow.
