Accuracy 🤔

I bought my CW Trident Atoll 3 months ago. For the first month I wore it religiously. It was running about +4 seconds a day every day for that month. I set it down to see what would happen if I let the power reserve run though. Well I waited 2 days till it stopped and started wearing it again. Ever since it’s been running -0.2 seconds a day. I mean I’ve personally never had an automatic this accurate. I’m wondering if this a fluke or if anyone else shares this experience.
