Yes, that appears to be the real thing. Â Nobody would fake that screwed back, seller has a lot of feedback, price is right, markings are correct. Â Jaeger was making quartz watches then to stay afloat. Â If you send it to Jaeger for service it will cost a bundle, so have a decent watchmaker replace the battery by removing those screws. Â It's probably worth around what it's selling for now, not a lot more. Â I suspect it is a pretty small case, maybe 32-34 mm, so it is for a smallish wrist. This is not a vintage watch, nor a vintage look. You ought to look for a 1960's Omega for a nice classic look, or even a late 50's vintage Rolex.
