  • Catalogue Essay

    The Patek Philippe deck chronometer ref 739 (like its sibling the ref 738) was introduced in the late 1930s for navigational purposes.

    It is interesting to note some movements were made earlier and later encased such as the present watch. The typical construction consisted for these precision timepieces featured an oversized case measuring between 59mm to 62mm diameter, and with a caliber 19”, 21” and 22” movement depending on the case size. The cases were manufactured in silver and stamped with the FFBA (Fédération des Fabricants de Boîtes Argent) Swiss silver hallmark. The dials typically carried the movement number enabling ease in check in the Bulletin certificates, and the watch would have originally been issued with a wooden deck box. These deck chronometers were produced in four series:

    • 738-open face chronometer with subsidiary dial
    • 738-1-open face chronometer with up/down indicator and subsidiary seconds dial with vertical orientation
    • 738-2-open face chronometer with up/down indicator and subsidiary seconds dial with a horizontal orientation
    • 739-open face chronometer with subsidiary dial, renamed reference 738, like the present watch

    The Stern Frères dials were made in metal, silvered or enamel.

    The present example features a movement made in 1914 but the watch was only sold in 1942 to A. Lünser a watchmaker based in Berlin whose name is further engraved on the inner caseback.

    The movement is superbly executed and finished, it features a fine adjustment, wolf’s tooth winding and a Guillaume balance, a balance made of steel and nickel alloy with anti-magnetic properties and un-affected by varying temperatures. It was an invention that enabled its inventor, Charles-Eduard Guillaume, to obtain the Nobel Prize for physics in 1920.
