Jaeger-LeCoultre “Masterquartz”

Swiss Watch Fair 1971 BF 303
Jaegor-LeCoultre’s quartz electronic watch with new styling. Yellow gold case, two-tone dial with very detailed centre minutecircle, quite normal for a time-piece of such precision (rate variation : less than one minute per year’!). (JAEGER-LECOULTRE “Masterquartz”)
