I mean, is it a MN24 (as you say) or an older watch sold in 2024?
In both cases, I would take it to the AD for an inspection. These movements are generally very precise.
My daughter owns a Black Bay that has exactly the same issue, -7 seconds per day, in all positions and however you wind it. In this case, the watch has surely been in the shop several years before we bought it.
