Dust under sapphire

Hi All,
Been loving my omega SS 3861 (2021). Beautiful watch and movement.
Noticed small bit of dust under the sapphire crystal recently (highlighted around it).

Worth getting a service under warranty or leaving it to the service in 5 or 6 years? Also has the movement issue with the chronograph where the watch stops completely occasionally (1 time every 20 times) when using the chronograph function.

I would get a warranty service for the chronograph stopping the watch. Mention the dust while you’re at it. I wouldn’t warranty it for the dust alone. I’ve used my chrono a lot and it’s never stopped the watch. That is not normal.

Send it for service. Get rid of dust and get movement working properly.
