How did you regulate your watch? Mine is running -15 sec a day for the last week consistently. I have never regulated a watch before, but I want to see if I can get this within COSC. Thanks

I used a pic from Puretime to show:
1st: I assume you don´t have a timegrapher. That´s fine, you don´t need one. I used the App "Watch accuracy meter" (Android, no clue if they have it for Iphone).
2nd:You open the caseback (Use a rubber ball or something with high grip, works like a charm).
Then you can see the balance.
3: you can se two levers on the balance. I marked them, 1 and 2. The Lever 1 is the Regulator and 2 is the stud holder. Never touch the mobile stud holder (2) if you don’t have a device to measure the beat rate with. You only deal with lever 1 and STAY AWAY from lever 2.
Moving the regulator (1) towards the stud holder (2) will effectively lengthen the hairspring and will make the watch run slower. So in your case you need to move 1 away from lever 2.
How do you move the levers: Do not use metal parts (might be magnetized and can also leave scratches) but instead a hard plastic tool is perfect. Some even use wood but I´m afraid of splinters falling in. I just used a plastic golfing-tee that i sharpened down to look like a flat screwdriver of 1-2mm width.
CAREFULLY move the lever. I mean that. a Millimeter can let your watch run minutes off per day. so just gently, very gently move it. when you have moved it a very tiny bit, just take the watch and hold it to your phone microphone to let the watch check the accuracy in different positions. Crown down or up, face down or up, etc. with caseback open. So when you managed to get like +5 crown up and -5 crown down for example, that´s fine.
When you moved it a bit too far, no worries, just move it back and forth until you get what you are looking for, a slight plus. It took me 2 hours until i was satisfied and trust me, I also moved it too far every now and then. Hope it helps!
Oh yeah and of course don´t touch the hairspring. Place the "flat screwdriver thing" or whatever you use at the side of the very end of the lever and gently push in a direction without touching the spring. It was actually the first time i did that, too, so just give it a try, worked for me.
