Dunno why this doesn't get more wrist time - it's a little bland looking but it feels great on; it's so solid you could drive nails in with it! Seiko 6139-7002 from December 1972. Acquired for about 20% of what it cost me to get it serviced and running
Those beautiful Big Eyes! 1960's Universal Geneve Uni-Compax "Big Eye" Ref. 884100/02 (UG Cal.125) & 1960's Seaboard-Yacht Chronograph - Valjoux 7733, 3rd edition blue dial. Manufactured for & sold by Seaboard Marine Supply Co. out of Islip, NY on Long Island.
Something has to be said about this dial/hands configuration combined with the blue insert which I've always thought to be amongst the most attractive of all brands of classic sports watches.
