I had it serviced at a specialist shop. The motor was also replaced, and the operation has been confirmed. The exposure meter also works, but it requires a battery (dedicated adapter included) as shown in the last image. It's an old model, but it's clean with no major scratches or dents. I was actually using it, but I'm selling it because I no longer have the opportunity to use it due to the rising cost of film.
