Chronograph is not running

[BFG9000]

Hello. I recently bought a repair kit so I could change my watch battery as it had died. It's a watch I found and it was never claimed so I kept it, so I don't know the make and haven't ever figured it out. Pictured is a blurry, crappy photo of the watch itself.

The problem is that the chronometer hand doesn't move at all anymore, which didn't ever happen in the several years I used it. I've also previously changed the battery once before, although a jeweler did that one for me. I changed it recently myself, but see no reason that I caused this. I didn't move/break/or really otherwise touch anything else.

I've tried

- Pressing each button, which should start/stop it

- Pulled the crown out fully and wound at least 24 hours through

- Pulled crown 1 stop and turned enough to set the correct day

- With crown out fully, pressed and held both buttons (I've been told by several sources that this should reset the chronometer)

- With the back cover off, I can see that pressing the buttons is triggering some mechanism underneath the little metal plate.

The watch keeps accurate time and the seconds hand does tick (although in odd design, the seconds hand says Chronograph over it, even though the big seconds hand is the chrono seconds)

I'm currently running the chrono (in that I pressed the button to turn it on) and waiting to see if the chrono minutes hand moves at all. A few minutes later, it doesn't appear to be moving...

You need to post a picture of the movent, not of the dial. So one can tell what it is and how much it cost to replace.

Here's a video. I press them each twice so you can see it, the second go is a bit more clear. I didn't show the crown being turned but it sets the time/date as it should)

I did like in the instructions and it didn't do anything. Is the pusher just the part you're pushing on with the button? Because that makes contact. In the video you see it cause the mechanism to change
