Jaeger LeCoultre Q8108420 Geophysic Universal Time SS Silver Dial

Reference Q8108420 belongs to the short-lived Geophysic revival that Jaeger-LeCoultre introduced in 2014, a technically ambitious line built around precision timekeeping rather than conventional dress-watch restraint. This Geophysic Universal Time pairs a 41.6mm stainless steel case with the brand's caliber 772, an automatic movement notable for combining a world time display with Jaeger-LeCoultre's deadbeat seconds architecture, a rare construction in modern serial production. The caliber runs at 28,800 vibrations per hour, uses 36 jewels, and delivers approximately 40 hours of power reserve. On the dial, the Universal Time layout centers the watch around a world map display and rotating 24-hour ring, giving the reference a more mechanical, instrument-driven character than the simpler True Second model in the same family. The silver dial variant offers a brighter and more restrained presentation than the more commonly seen blue execution, while still preserving the line's clean applied markers and sharply faceted handset. Jaeger-LeCoultre rooted the Geophysic collection in the legacy of the 1958 original, but this reference is firmly contemporary in its engineering and display logic. The black alligator strap keeps the case profile lean and emphasizes the watch's crossover appeal between travel watch and modern daily wearer. No evidence surfaced that Q8108420 was a country-specific, boutique-only, or numbered limited edition, so it is best understood as a standard production reference from the mid-2010s. For collectors, the appeal is the combination of an in-house world time caliber, deadbeat seconds, and a case design that sits outside the more familiar Master Control and Reverso catalogues, giving the watch a distinct place in recent Jaeger-LeCoultre production. Excellent Condition with Jaeger-LeCoultre box.
