what your showing doesn't indicate is a watch

Old post, I know, but I was browsing around and saw that the mark wasn't identified and the OP hasn't revisited recently. Nevertheless, this may help someone in future.
It's the trademark of Société Suisse d'Horlogerie / Montilier Watch Co. SA of Montilier in Switzerland. The mark was registered in 1880. They made watch cases and movements.
