Lot Essay
Accompanied by Patek Philippe Extract from the Archives confirming production of the present watch in 1974 and its subsequent sale on 10 April 1974. To the best of our knowledge, it has never been offered at auction before.
Reference 3603 was in production from 1973 until 1982, the majority made with yellow gold cases. The present watch is thought to be only the fifth example of this reference in white gold to appear in public to date.
The Beta-21 caliber was developed by a consortium of watch companies, including Patek Philippe, at the Swiss Electronic Research center or CEH (Centre Electronique Horloger) in Neuchâtel. It was the first quartz movement for wristwatches with analog 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.
