Jaeger-LeCoultre Master Grande Tradition à QP 8 Jours SQ

First Look…

Master Grande Tradition QP 8 jours SQ

This is the new Jaeger-LeCoultre Master Grande Tradition à Quantième Perpétuel 8 jours SQ, inspired by a historical Grande Complication pocket-watch from 1928.   This watch combines the best of enameling, openworking (aka skeletonizing/squelette aka “SQ”), and engraving in addition to the highly complicated Jaeger-LeCoultre Caliber 876 perpetual calendar movement in skeletonized form.

In addition to the time, the dial also displays the the date, the day of the week, the month, the year (which is absurdly challenging to read , and the age of the moon. There is also a power-reserve indicator and a day/night display with a red safety zone highlighting the calendar’s daily switching phase (i.e. indicating a time not to be setting the watch!).   You can see the pusher on the side of the case (~8 o’clock) that advances all calendar displays one day at a time for easier setting.

You can see in these images how the watch has been meticulously openworked and engraved.

Also, on the outer edge of the case — both front side and back — is ringed with bleu enamel, done in the grand fre “champleve” method.  Of course the press image renderings here do the enamel modest justice at best — the actual surface is delicately polished and will exude its own unique character and hue of blue.

A splendid watch with not only the heralded perpetual calendar function but representing a fine demonstration of the unique character brought on by master engraving, enamelling and skeleton work.

Nicely done Jaeger-LeCoultre.

    The blued hands on the original pocket watch seem to fit in with the rest of the design but they don’t seem to work on the watch – at least not in the pictures…
    Good example of fine horology though.
