JAEGER-LeCOULTRE Geophysic True Second - Ref. JLQ8012520 - 18K Rose Gold - Box& Papers 2017 - JLC Service 09/2026 - Excellent

A superb Jaeger-LeCoultre Geophysic True Second, reference JLQ8012520, presented in luxurious 18K rose gold and distinguished by its refined combination of classic design and innovative horological engineering.

The watch features a beautifully understated silver dial with rose-gold applied indices, perfectly complementing the warm tones of the 18K rose-gold case. The elegant dial is paired with a brown alligator leather strap and the original Jaeger-LeCoultre rose-gold pin buckle, creating a sophisticated and timeless aesthetic.

At the heart of the watch is the Jaeger-LeCoultre caliber 770, an automatic movement featuring the distinctive True Second function. Unlike a conventional mechanical seconds hand, the True Second hand advances in precise one-second intervals, giving the watch the visual behavior of a quartz timepiece while retaining the craftsmanship and mechanical character of a traditional automatic movement.

This example comes as a particularly attractive complete set with original box and papers dating from 2017. It has also benefited from a Jaeger-LeCoultre service in 2026 and is offered in excellent condition.
