Here are the Mikrolisk results for Leuba, including your Leuba Louis Geneve:

Trademark was registered in 1965, to Louis A. Leuba. I think that your watch is somewhere from between late 1960s and mid-1970s, but that's just based on the design, nothing else.
If you post a picture of the movement, we'd be able to tell you more.

 

Thank you, that is a great starting point. I am reluctant to open the case myself but may get somebody to do it and return with a photograph.

 

If you intend to collect vintage watches, get a case knife- it's blunt, so not that much of a risk to scratch a watch. Also, a watch holder will be useful. It's a rather basic equipment, but really useful. Ask a watchmaker to open it for you if you do not have the tools or not intend to get them- he shouldn't take any money for opening the watch up. I'm always writing this "warning", since there were a few times when I have heard of watchmakers who do take money for that (or rather take money for nothing, that's more like it).

 

Nice looking watch there. I've had a few of similar design with no second and similar casing style. All had a Peseux 7040 inside.

 

I fear that this one will just have a small ladies' "form" movement inside. I have seen watchesd with that sort of case and they had things like this insde:

The fact that the hole in the back is rather smaller than the case and that the watch lacks a seconds hand leads me to believe this.

I came across this thread when searching for information on Louis A. Leuba. All I've been able to find is that the company was established on 7 July 1952 and was dissolved on 7 October 1996. I have two chronographs by this company, both with the good-quality Venus 188 movement and each of which cost me under £200. They will probably cost more than that to service. It's somewhat crazy that there are other watches with the same movement that would cost getting on for ten times the price of these. Anyway I like these and if anyone's interested in seeing them, here they are. Both dials are original and unrefinished. There's a bit of plate loss and I'll probably get the black one replated. I've test-run them for a day and they both keep excellent time.
