How accurate is your 1120?

I purchased a 2254 from the bay earlier this year. The seller stated watch was serviced in 2015 and provided spare parts to prove it. I hadn’t paid much attention to the accuracy until recently. I set the watch to my atomic time app on 7/15 this month. It fell behind a few seconds for a few days and slowly started gaining. I checked this morning (7/29) and found it was +3 seconds. Average that out and I have a watch that has run +0.21 seconds for 2 weeks. Curious to know what others have seen from this movement. I have a 2255 “electric blue” that runs a consistent +5 per day. Being that it is so consistent, I wonder if it too can be regulated to the same accuracy as my 2254?

.20sec per day.
Was my watch for a year, then sold it to Woman to help subsidize a Speedmaster Pro. She dives in it regularly, as well as general, everyday wear. It doesn't get treated with kid gloves.

My 1120 SMP was always +2 until I sold it.

I’ve tried regulating my 2255 and can’t seem to get it just right. It either runs 5 seconds fast or a second slow per day. Either way it’s within COSC standards, but would love to see it run as good as my 2254.

+4 seconds a day.
