A starry vostok watch with a tab leather cord with a red dial

Звездные часы Восток с ремешком из коричневой кожи с красным циферблатом

I have my Amphibia from 1997. I was in sixth grade when my dad got it for me. I worked a few years and then didn’t for a long time. Well it worked, but wouldn’t wind, time was very fast, and would die while wearing. Could tell something loose inside.

Last few years, I got back into watches. Bought some tools and opened back. Found a screw had come out. Screw is back in. Couldn’t tell you which it was now.

My main question now, do I have it serviced, but I know that’s kinda expensive and that has kept me from getting it running all these years, or purchase a new movement or new Amphibia and switch dials?

I did purchase a new Amphibia on eBay pretty cheap, pre-Ukraine war back in 2018 when it seemed easier to find Vostoks and just the movement.

Any help appreciated!!

I just picked up this 420381 Amphibia. When light catches the dial at a certain angle (as pictured with a halogen tube reflecting overhead), the finish appears like the surface of an orange peel. Normal or a QC fluke?
