@Giovannii
Do you have pics of before the service?
both
@kaplan and
@gbesq are correct.
The lume is poorly done and your watchmaker should have asked before he carried out such a major change to your watch.
However, if the lume fell apart when removing the hands he may have replaced the filling as an additional service. ( as a benefit or to cover some clumsy hand removal)
Did he charge an additional amount for reluming?
Does the lume glow (ie is it superluminova?)
Either way, communication is key here - talk to your watchmaker and have him rectify the blob and colour match the lume.
While he’s in there, ask him to regulate the movt.
Unless there is something worn in the watch (which he should have mentioned) a cal551 should be able to run spot on and not not 20 secs out.
BTW is there something going on with the minute hand just beyond the lume?
It looks a bit odd in some of the pics.
