Seldom seen 1960’s Calatrava reference 3440 which is a self-winding watch utilizing Patek’s 27-460 movement. Very nice condition with a tiny ding on the bezel around 7 o’clock which would potentially be minimized with some light work from a polishing cloth. Sharp and clear hallmarks on both sides of the lugs. Prominent raised enamel Patek logo which goes well with the thick, rotund bezel. Non-Patek buckle and strap.
