What does the dial look like?

The dial is legit, the current service cost for a Futurematic is $600.

It's a U.S.A. market watch, for which JLC Switzerland has no records. Sometimes, if there is a number. in addition to the case a serial number of the case back, that is the case reference. I can service your watch at approximately 1/3 of the factory cost, assuming no parts are required. See here: ht...

The 2 register ones usually have UG movements in them.

Any gold LeCoultre is "relatively rare" but it doesn't necessarily translate into huge dollar amounts. The dial on this watch has been refinished. Value is under $1000 in my opinion.

Hi, this isn't a military watch per se, but a "military-like" watch.

I would say spend your service money on a watch that has a higher value than this one as you'd be underwater if you ever decided to sell it.

It's the same family.

Next one that comes in for repair, I will note what our shop used for the crystal.

How do you know it's an original crystal is more my question. In my opinion, there is no way to tell, so best not to worry about it. If it clears the hands you are likely to have the right crystal profile anyway.

How do you know that is the correct dome height?
