The 1960s and 1970s were tumultuous times in the watch world as the introduction of the Quartz movement threw the watchmaking world into panic. These new movements were powered by battery and ran more accurately and dependably than their mechanical predecessors. The very first reference that Patek produced with a quartz movement was the reference offered here, the Reference 3587. Large in scale compared to other Patek Philippe watches and futuristic in design, this watch stood out in the catalogue and made a lasting impression.
