With Patek Philippe Extract from the Archives confirming production of the present watch with applied gold luminous hour markers in 1956 and its subsequent sale on 28 May 1957.
To the best of our knowledge, this watch has never been offered in public before.
In today's market, reference 2508 is undoubtedly amongst the most popular "time only" wristwatches by Patek Philippe. Its plain yet masculine and sporty look make it a great collector's watch, especially since its case proportions are very much identical to the much celebrated screw back chronograph reference 1463.
Reference 2508 was launched in 1951 and remained in production until around 1960. The model is illustrated in Patek Philippe by Martin Huber & Alan Banbery, 2nd edition, p. 204, pl. 328.
