Jaeger-LeCoultre Master-Quartz Owner Review : Amazing, innovative and symbolic

I fell head over heels for this model to the point of buying two! What a thrill this watch is, which for many takes up the codes of the Patek Philippe Nautilus while the two I have date from 1972… including one from March 1972, before Basel World of the same year which will see the presentation of the Royal Oak! And yes, this Jaeger-Lecoultre Master-Quartz is equipped with the Girard Perregaux GP352 caliber, one of the two Quartz calibers developed by the Swiss watch industry with that from the BETA21 consortium. Note that Girard Perregaux was at the time one of the most innovative Swiss brands. This watch is therefore equipped with a battery and a Motorola chip allowing the watch to be dated with a number showing the date of the week and the year! This JLC therefore predates Gerald Genta's two blockbusters. Its design has everything to please me, TV box, integrated bracelet from Chatelain, absolutely fantastic striped blue dial! What is it missing? Reliability, quite simply! An electronic circuit that is over 50 years old was not designed to have such a long lifespan... So it is a capricious watch far from being able to be used as a Daily! No problemo if we have understood this paradigm.
