How much time is it losing? Is it ETA?
BP Factory is known to install crappy old, used movements in their "ETA" powered reps.
It's an ETA clone, and it looses quite a few seconds a day. I'd say within 2 weeks it's two minutes slow or so, and will require a resetting. Never appears to gain any time.
Like I said I sent it out to one of our modders, whom now is kinda inactive around here. I paid him to overhaul it, but same result, never gains time, always looses.
