This watch sports the in-house Yama 3000 movement with 29 jewels. 42 hour power reserve and beats at 4 HZ. The watch has only been worn a few times and used for a YouTube video. I have everything with the watch including the bracelet, case and paperwork. I also have four extra links for larger wrists. The watch has a bi-directional bezel and GMT function that tracks three time zones.
