With Patek Philippe Extract from the Archives confirming production of the present watch with Beta 22 calibre in 1974 and its subsequent sale on 10 July 1974. Furthermore delivered with copy of the retailer Grauwiler Basel purchase invoice dated 25 November 1975.
To the best of our knowledge, this watch has never been offered at auction before and is believed to be one of less than 10 examples of a reference 3603 in yellow gold with blue dial to appear in public to date.
Reference 3603 was in production from 1973 until 1982 and is together with references 3587 and 3597 amongst the largest rectangular wristwatches ever made by Patek Philippe.
The Beta-21 calibre was developed by a consortium of watch companies, including Patek Philippe, at the Swiss Electronic Research centre or CEH (Centre Electronique Horloger) in Neuchâtel. It was the first quartz movement for wristwatches with analogue display.
For a similar watch and description and illustration of the Beta-21 see Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, pp. 85, 87 & 332.
