Lot Essay

With Patek Philippe Extract from the Archives confirming production of the present watch in 1971 and its subsequent sale on 10 November 1971. The Extract further confirms the white gold bracelet.

The present watch is fitted with the celebrated Beta-21 electroquartz movement, developed by a consortium of watch companies, including Patek Philippe, at the Swiss Electronic Research Centre or CEH (Centre Electronique Horloger) in Neuchatel. It was the first quartz movement for wristwatches with analogue display and introduced at the Basel Fair in April 1970.

The first model of the series, reference 3587 such as the present watch, was fitted with caliber Beta-21 and became reference 3597 in 1973 with the introduction of Beta-22. It was in production until around 1982. Reference 3603 was introduced into the market in 1972, also until around 1982.

The three models, the largest wristwatches ever produced by Patek Philippe, were available in different case, dial and bracelet colours and variations and are highly collectable timepieces.

References 3597 and 3602 as well as the Beta-21 are described and illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 332.
