Picked up a watch new recently with an ETA2824 in it.

It's not keeping great time at the moment at about +25 a day and at £1000+ that doesn't seem correct.

Are running in periods still a thing or is it worth getting looked at straight away?

Is regulation of a 2824 something one can do with a suitable set of tools (minis a timegrapher) or more a job for a watchmaker?
