Reference 840 was produced from 1951 to the late 1960s in a very small series of approximately 30 pieces. To date, less than 10 pieces are known to the experts. This rare sports chronograph is powered by the famous 13''' chronograph movement which was commonly used in wrist chronographs of that time. The silvered dial has black, distinctly raised scales and the Patek Philippe logo in the centre as well as applied silvered indexes and Arabic numerals; an angular ring for a neck loop sits at 6 o’clock. The screwed back protects the movement from exposure during outdoor use. This probably makes it the only Patek Philippe pendant/pocket watch with screw back.
A few examples of reference 840 are illustrated on pages 28-29 of "Patek Philippe Steel Watches" by John Goldberger, 2010, page 189 "Patek Philippe" by Huber & Banbery, 1982, and page 313 of Patek Philippe Museum, Volume I, 2013.
