Omega Speedmaster dust

Hi there,

I've owned my Omega Speedmaster 2021 saphire for coming up to a year but have recently noticed that it had a small black dust spec in the exibition case whilst I was admiring the movement!

I was wondering if any watch experts could fill me in with what they would recommend I do. If it will be no problem then I'm happy to leave it till service but I would want to get it rectified if it is going to likely cause an issue down the line.

Please find the attatched image:

Unfortunately, dust can appear. Is it still under warranty? The OB can get it taken care of but they will have to open the caseback and do a full service. Had a similar issue with my watch that was under warranty--they took out the dust fleck and also adjusted the amplitude. No polish or part changes.
