For sale is a Jaeger-LeCoultre Master Quartz, reference 23301-42, dating from the mid-1970s. With serial number 1,384,836, this watch belongs to the very first generation of Swiss luxury quartz models, produced when Jaeger-LeCoultre embraced quartz technology during the revolutionary 1970s. It represents both a bold design statement and an important milestone in horological history.

The watch is in very good condition. It features the iconic oval stainless steel case with polished and brushed surfaces, measuring approximately 39 × 46 mm. The dial is a refined silver sunburst finish, set with elegant linear indices, luminous baton hands, central seconds, and a date window at 3 o’clock. At its heart beats the Jaeger-LeCoultre Calibre 352 quartz movement, one of the earliest high-precision quartz calibers developed in collaboration with Girard-Perregaux, based on the Beta 21 platform.

This example comes with a new old stock (NOS) unworn Jaeger-LeCoultre leather strap and the original Jaeger-LeCoultre buckle, which adds a rare period-correct detail. The watch will be delivered in our watch roll for secure storage and presentation. Please note that this is an only watch sale, with no original box or papers included.

The watch has been inspected by our Omega-certified in-house watchmaker in September 2025 and confirmed to be in excellent working order.

As a vintage model from the 1970s, the Jaeger-LeCoultre Master Quartz Ref. 23301-42 captures the futuristic design language of its time and reflects the technical innovation that defined an era. Its unique styling, historical importance, and excellent preserved condition make it a compelling addition to any serious watch collection.
