It runs like a charm???? :thumbsup: Yes!

[Awaken]

Runs smooth as silk. (closer match with la seda).
Runs like a dream.
Runs like a top.

I personally wouldn't use "charm" with the verb "runs," but the meaning would be easily known.

Agree with Awaken. 'It works like a charm' is more commonly said.
