This watch is probably unique because the tachometer scale is located on the inside of the outer ring, and not on the outside, as is usually the case, and the numerals of this scale are horizontally oriented as opposed to a more usual radial orientation. This particularity makes this watch especially rare and interesting.Ref. 1436Split-seconds chronograph wristwatches were "the must" of Patek Philippe technology and after 1938 were generally cased with this Reference.The majority are in yellow gold. Rarely, they are in pink gold, and only three stainless steel examples are known, two of which were sold by Antiquorum:- Geneva, April 10, 1994, lot 431.- Geneva, April 23 1995, lot 457.In the mid-1950's some were produced with a coaxial button on the winding-crown for the split-seconds functions (stop and reunite).
