However, there is no other Le Coultre Memovox with a dial like this.

This is my Le Coultre Memovox Jumbo 14 kt case 38,5 mm. The index at 6 and 9 seem look like those like the Cross of Vacheron. It is possible that there was a collaboration with Vacheron for the construction of this wristwatch?

Thanks for the answere.
