Power reserve only 12hrs or so

I've got the AR Factory Sub 904L version for about a month now. The power reserve rarely lasts over night, about 12 hrs after wearing all day. Hand winding, I'd maybe get over 12 hrs.

Is there a way to increase it by servicing or to the extreme end ...can an ETA movement be swapped in in an economical way (ie. cannabilizing another watch)?

How have any of you gotten the best performance from your reps?

Service will fix.

You can swap in ETA but make sure it has tall cannon pinion, otherwise the hands will be too low (close to the dial) and incorrect for Rolex. Standard eta movement has short cannon pinion. I would just service the existing movement or try to live with a 12 hour reserve...I do not need more than 12 hours for my requirements.
