You need to ask Zaf Basha,
www.classicwatch.com. He's got a special section on his website where people can ask for (free) estimates of JLC vintage watches. He wrote an authoritative collectors' reference book about Jaeger LeCoultre watches.
But before you do that you need a very crisp picture of the dial so people looking at it can make sure it hasn't been refinished. Serious vintage collectors simply don't buy "redials". At the very least it would lose 60% of its value if refinished.
This picture cannot be used. You also need a more crisp picture of the movement so its condition can be ascertained better.
You can post here first if you want so people can tell you if it's good enough.
Cheers
