  • Catalogue Essay

    Patek Philippe’s groundbreaking reference 1526 was a landmark model as it was the very first serially produced perpetual calendar wristwatch. Launched in 1941 and in production until 1952, it forged a new path for the manufacture and would set the benchmark and standard for many perpetual calendar models to come.

    The apparent simplicity of the case and dial underlines the exquisitely complicated movement, one that mechanically calculates the length of each month throughout the year, whilst also accounting for leap years. Over the decade reference 1526 was in production, only 210 pieces were ever made, the large majority in yellow gold, an extremely low number in pink gold and only one in steel known to date.

    The present lot is amongst the first generation models produced as it has a double circle around the aperture for the moon phases, one indicating the constant seconds, the other one the date of the month.

    The attractive dal displays minimalist Arabic numerals, retains its original hard enamel printing throughout. The present watch is furthermore housed in a well-preserved pink gold case, with a crisp hallmark beneath the lug.

    A truly special timepiece, it will appeal to the collector looking for not only a very well preserved and extremely rare specimen, but also one of the first perpetual calendar wristwatches ever made.
