Hamilton offered many European designs often not found in the U.S. catalogs in the late 60’s & early 70’s. These often had reference numbers 640XX - X. This gorgeous 1960’s Hamilton 600 Broad Arrow Diver Ref. 64034-3 is powered by cal. 64A, same mvt. as the 600 Super Compressor cased model 64040-3. It reminds me of the iconic Omega Seamaster CK 2913. Perhaps my favorite fine of 2019!
