So close

Soft-serve machine.... it looks like it controls flow for dispensing something

We have already covered this. Yes it dispenses something. Not ice cream or sno cones

Not really. I googled @shane0911s object and it showed me a bunch of wristwatch parts but didn't say the name of any of them

Part for a cotton candy machine?

Not part of a wristwatch or a cotton candy machine

Think shopping malls and grocery stores and barber shops

ICEE? Slush puppie?

That would be a big ass wristwatch.

NO
