OK thanks panerai153. I will be sure to get it serviced. Do you know roughly how much this should cost me? I know i'm going to be quoted a range of prices and don't want to ripped off.

Thanks everyone. I rarely wind it as I wear it non-stop, so I've given it a proper 40 revolutions and I think it's already better. Will report back in a day or so to see how it's been keeping.

Aeromatic - Thanks for the info. Do you think it's best to get this done at a watch shop "in town" or send it back to original seller to get it serviced? SSTEEL - I will be sure to share a positive experience as soon as possible. I just wanted a bit of help. Apologies.

Hi all, A year ago exactly I purchased a Swiss ETA-2836-2 25j automatic Submariner. The watch was great, could leave it off for days with everything still ticking on, no loss of time. Recently it has been playing up. I'll take it off and it'll stop within the hour. It doesn't keep time. Falls behind over a day. I know the movement was second hand in the first place, but this seems odd for a swiss 25j movement? It's acting like an Asian 21j cheapo. Anyone have any thoughts? Or is this normal? Thanks v much
