Accompanied by Patek Philippe Extract from the Archives confirming production of the movement in 1909. It was completed and encased in 1963 and sold on 9 February 1965.
To the best of our knowledge, the present watch is the only example of a reference 841 known to exist to date. Part of Patek Philippe's "Série Moderne" made in the 1960s, including references 836 to 839, 841 to 845, 847, 850 and 853, it was only known from literature.
Fresh to the market, this watch also features the rare and desirable tandem wound two train movement, one for the going and one for the repeating work. Traditionally, the repeating mechanism of a watch is activated by pushing a slide in the case band, thus winding and releasing it at the same time. The train of a trip repeater is wound in conjunction with the going train and released at will through a button in the crown. The advantages of this system are the clean lines of the case, the enhanced dust resistance and most importantly permitting the owner the activation of the repeat train many times at will from only one winding.
