I have had this watch for quite some time, but unfortunately didn't have the chance to post the pictures here. I guess this watch uses a Seiko movement because the face design is very similar to Seiko SPC003P1. I have not opened the case back so I'm not sure about it, but the dial configuration is the same.
Here's the video I have made of how the chronograph functions:

I'd be glad to answer your questions.
