OK REDID IT. IT SHOULD WORK NOWThe video is still not working… Did you make sure you published it and made it available to all?
Just quizzing myself- would it be gaining time because a worn bushing would be robbing power from the escapement and causing the balance to swing with less total rotation and therefore increased BPH?If it is gaining time, the problem is almost always worn out bushing.
As already stated, the movement is a Hermle. There are two sizes available, yours takes the larger one. It's called a 'click wheel' but non clock people usually call it a ratchet wheel.
Other parts may also be damaged.

I got the the new wheel in. And a new spring . Wind it all the way up and it's working great. Using pegwood to clean out the holes and reoil it. It my frist clockThat's an old style stamped click wheel. Hermles now have a machined version.
Hopefully the new wheel will be the improved versionm. If not, it would be a good idea to 'improve' it yourself, as Bugs just mentioned. Willie X
