This.
I don't know the specific movement in that watch, but a quick google search indicates Miyota (Citizen) Automatic movements have an accuracy tolerance between -20 and +40 seconds per day. So you are doing good methinks. It might settle down with time. You could take it to a watchmaker and see if they can regulate it, it may be possible to make it better, but it most likely will never run to COSC Chronometer standards.
My Tudor Black Bay is accurate to a few seconds per week, but it's a Certified Chronometer and cost several thousand dollars.
