Hi, everyone:
I've just joined this forum, being a new first-time owner of a Jaeger-LeCoultre watch. This is a 6B/159, with MOD dial and cal. 450 movement. Now, I was wondering, is it possible to get an idea of manufacture date for this watch, other than by paying Jaeger-LeCoultre 250 Swiss francs to look up the watch in their records? The movement's serial number is 143563, and the watch's RAF serial is A20330. Thanks!
