Antique Swiss made, 8 day, travel clock in leather case

This is a very old travel clock with a leather case. One the face it says Swiss made and above that it says 8 day. There is no writing on the back of the clock part. I would like to know who might have made it. The back has hinges L Sandoz Vuille is stamped on the inside with the serial number 179582 and it says 6 jewels. Anything that you can tell me about this little travel clock would be appreciated. I can't seem to find one with a leather case anywhere!
