Common questions about the Jaeger-LeCoultre Geophysic Q8108420

How big is the Jaeger-LeCoultre Geophysic Q8108420?

The case measures 41.6mm across and 11.84mm thick. Case material: Steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

What movement is in the Q8108420?

Automatic, Caliber 772. Power reserve is 40 hours. It beats at 28,800 vph.

Is the Q8108420 water resistant?

It is rated to 50 meters, about 164 feet. That covers brief swimming. It is not a dive watch. One caution that applies to every watch on this page: a water resistance figure describes a new watch with fresh gaskets. On a piece that is years past its last service, treat the rating as unknown until it has been pressure tested.

Does the Q8108420 have a nickname?

Geophysic Universal Time. Collector nicknames are not official Jaeger-LeCoultre names, but they are what people actually search for and what they are called across a showroom.
