Question regarding the ETA 2784

I'm curious to know the power reserve time and also the bph, (is it 28,800)?

Thanks,

Greg

Yes its a 17J 28800 BPH movement but power reserve would be closer to 42 hours.

Yes as there is wear in the barrel and the spring gets weaker over many many years. But power reserve on a full manual wind around 36-42 hours plus or minus a hour or so.
