With Patek Philippe Extract from the Archives confirming production of the present watch with diamond indexes in 1957 and its subsequent sale on 23 October 1957. To the best of our knowledge it has never before been offered in public.
Reference 1593, launched in 1944, is one of Patek Philippe's best designs ever given to a rectangular wristwatch. For over 20 years, this model was available in gold, only few examples were cased in platinum. It is interesting to note that the majority of reference 1593 in platinum was fitted with the diamond-set dial (see lot 423 in this auction).
The model is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pages 128 & 129 and 141 & 142.
