With Patek Philippe Extract from the Archives confirming production of the present watch with diamond hour markers in 1949 and its subsequent sale on 5 December 1949.
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. The present watch fitted with the attractive diamond-set dial represents a most elegant and rare version of this reference.
The model is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pages 128 & 129 and 141 & 142.
