Regulating a GMT Seamaster

Hello everyone. I've got a Seamaster GMT 2535.80 Co-ax which I've had for a few months now and am very happy with. It runs very consistently at about 3 seconds fast per day. I don't mind this and I know it's well within COSC spec, but was wondering if I could get it regulated at my dealer to slow it down 3 secs per day, leaving it in theory keeping perfect time?

Specifically I was wondering:
- if any AD can regulate the watch or would they need to send to Omega?
- what the increments are by which a watch can be regulated i.e. can they specifically slow it down by 3 seconds, or is it a case of a quarter turn of a tiny screw somewhere which may or may not slow it down by about 3 seconds, give or take a bit?
- any reason I shouldn't get it regulated with the aim of getting it to run within 1sec per day?

Any answers, opinions or advice appreciated.
