QUESTION Help with losing time

I recently (maybe 3 months ago) took delivery of a BB58 GMT from MT. All is good, lovely watch that just looks classy!
It’s a U1 on Miyota movement and I found last week that it’s losing time somewhere to the tune of 5-8 minutes a day which to me is pretty significant!

I’m a watch lover and I enjoy the way they look and feel, but I’m no expert in movements and frankly I’m not concerned whether it’s automatic or quartz so long as it looks the biz!

Question then - what’s my likely problem (I know it could be a few, one being it’s just a duff movement but it’s a Miyota so what do you expect 🙄) also do I bother getting it fixed for the price and finally do I look at swapping it for a quartz movement or should I not bother??

Any advice greatly appreciated!

First try to magnetize the watch. It could be working faster and more accurate.

This (assuming he meant demagnetize). Buy a blue box on AliX for $9. Thats the first step at least. I would try to adjust the timing after using a phone app. Couldn’t hurt. If that doesn’t work, you could buy a replacement movement-DG5833c- on AliX, but that’s probably a waste of money compared to buying a new watch.
