Just NY 2 cents and someone may have said this as I admit I have had half a bottle of champagne and 1 of wine ( with my wife not alone) so I haven't read through it.
99% OF PEOPLE CLAIMING +1 OR PERFECT TIME HAVE ABSOLUTELY NO IDEA WHAT THE ARE TALKING ABOUT, and most often pull that figure from their ass because that's what they want to project.
As an aside, if you need 100% accuracy at all times then a mechanical watch is not for you and a digital one is a better choice. I don't mean this as an obnoxious attack, it is simply that hand wound and automatic watches have never been atomic time watches. Very few people and professions require " to the second" time accuracy, and those that do ( let's say you're a navy seal coordinating an operation with 6 other units including detonation) know very well hot to get it and from where... Like a good old g shock.
Yes, you should be able to tune it ( regulate it) to make it slightly better. It's an easy adjustment that a watchmaker will take all of 20 seconds to perform... Or maybe a minute which on your watch will be about 58 seconds

As for the watch running fast that is healthier than slow since A/ it will get better with time and B/ it's very easy to reset weekly by just lifting the crown for a few seconds.
Lastly. If you're not happy with it and you can still return it do it and do it fast. Experience tells me you will not get more fond of it with time but rather less, and by then it will be too late.
