What’s the best way to polish a watch bracelet with a lot of micro scratches AT HOME?

I would like to bring my wife’s everyday watch to its former glory, but I have no tools or a shop available.

Is there a simple way to polish it (it’s the bracelet I’m looking for, the watch itself isn’t even that scratched) at home by hand? The scratches are very minute, not deep, just a lot of them.

Any good reference YouTube video for this?

I’m not looking for it to be perfect by all means, I just want to get rid of 80% of the marks and make it look better.

Thank you for helping a noob.
