Notes

Ref. 3587/1Production of this reference started in 1970.The firm Patek Philippe with other Swiss manufacturers became part of a new company "Electronic Watch Centre" (CEH) to jointly study a quartz wrist calibre. Developed and finished after one year of research, the calibre Beta 21 (29 x 24,3 mm) was ready for production in 1969 and was presented at the Basel Fair in 1970.A similar watch is published in Patek Philippe Wristwatches, by Martin Huber & Alan Banbery, 1998 Edition, p. 332.
