The Geophysic 8108120 (aka: Q8108120), seen from the bench
The Jaeger-LeCoultre Geophysic 8108120 (Q8108120) is a modern interpretation of the 1958 original, engineered for intense magnetic environments. It features the caliber 772 manufacture movement with jumping seconds and World Time function for 24 time zones. The stainless steel case measures 41.6mm with mixed finishing—satin on the sides, polished on the angles. The 20mm lug width ensures compatibility with standard aftermarket straps, though the integrated lug design requires properly dimensioned straight-end straps for visual alignment.
