Jaeger-LeCoultre

Long time no post ! I was hoping someone could help me date this travel alarm clock ... please see pic Any help is greatly appreciate, many thanks LeCoultre 2 day travel clock...  

I was thinking 60's ... my local clock repair shop said it's genuine lapis on the dial as well. Googling around I haven't found but a couple 2 day travel clocks with lapis dials. What features yield the 60's - 70's guesstimate in your eyes ? And thanks fo... 

And I don't think JLC did something like this after the 70ies. Superb dial, indeed. Best, Nicolas.

Ahhh ..... interesting :) This may show my noob level, but I didn't realize that was tritium lol :) I have owned tritium sights for a Glock before, but didn't realize tritium was also on that clock lol. Thanks again, it's much appreciated :)
