A old chronograph Suisse !
A reasonable watch made as Souvenirs for tourists I believe/ according to internet, same as swiss chocolate, cuckoo clocks ect
Is it running ? The minute hand could have a broken pinion but may have just fallen off !
Probably Landeron movement but maybe a Valjoux . It looks like a thin gold plated/ capped case, the case backs had to be reinforced as the gold was so thin . Yours looks to be in good condition and should polish up nicely.
Value wise not a great deal as it's got some issues , a couple of hundred at the very best.
