If you want to actually try on some watches, try Wanna Buy a Watch on Melrose. They have a very nice selection of vintage everything, Subs, GMTs, Day Dates, Date Just etc., and other brands. Oliver and Clark, by appointment only but a very large assortment of rare vintage Rolex and others. Just down the street from LACMA. Second Time Around has a few Date Just only (usually) but worth a look, just south of Wilshire on Beverly Drive.
