As Nicolas, I have been very doubtful about this version.
Is this the original box for this watch?
Never seen this mix of JLC and LC marking on box, hangtag and strap.
But more importantly - never seen a Memovox with the date window at 4:30.
Would be interesting to see the movement and case back markings.
Congrats and enjoy - always great to find a NOS piece!
