recently I noticed that my speedy works loud when I move the wrist. Its like the automatic mechanism frictions (maybe with caseback?) when used. Besides the watch works well. Should I worry?

The sound you are describing sounds like the bearing in the oscillating weight is worn out, allowing too much play. This allows the weight to scrape against the inner cover. If the previous service didn’t include a new bearing you may need to have it replaced.

well, having in mind that there is DD module, i hope that its possible to just replace the bearing and not the whole mechanism?

It’s part of the base movement so not related to the module.
