Jaeger-LeCoultre has updated the Geophysic True Second with a deep blue dial, exclusive to its online boutique

The Jaeger-LeCoultre Geophysic True Second first launched in 2015, an elegant 39.6mm watch with a dead-beat seconds hand (read our hands-on review here). 
Jaeger-LeCoultre has now released a new limited edition variant with a dark blue sunburst dial, sporting silver hour markers and triple-faceted matchstick hands.

The original Geophysic was launched for the International Geophysical Year in 1958, a tool watch for a year of cross-border scientific collaboration that marked a relaxing in Cold War tensions.
A reinterpretation of the original 1958 chronometer, the new Geophysic True Second retains the instrument feel – the cross-hairs can be seen clearly in the centre of the dial. The new blue dial shade does bring a little more fun to the watch than the 2015 white dial did.
