I am new to this watchmaking hobby, and on the re-assembly of a watch I took apart to replace the movement, I had this shiny, black metallic dial that I simply could not get clean.

No matter what I did, dust in large quantity would find its way onto the dial. To me, it seemed like a static charge was being created somehow because brushing and blowing only made things worse.

Just wondering if I’m the last one to know the solution to this or maybe I need to build a clean room, ha.

Wondering potential causes of limited power reserve on an automatic movement.

Received a new Chinese NHxx movement for a build that only runs a few hours, have to set it every morning.

Has zero beat error and +- 5 sec/day.

The only thing I could guess is broken or overlubricated mainspring but being new to this hobby I’m looking for experienced opinions.

Easy enough fix for me, just gonna swap the movement and disassemble the one from the watch to learn…

I had an NHxx movement running well and being new to the hobby, I removed the balance just to practice installing a balance.

The movement refuses to run now, and I’m struggling to understand what it could be.

I didn’t break anything. I removed, cleaned and lubed the cap jewels to see if that would help, No luck.

Just wondering if anything jumps out as a cause to the experienced.
