The Air-King 14000 has an in-house (developed and manufactured by Rolex) caliber 3000 automatic, self-winding movement. The specs list it as having a 42-hour power reserve, but due to the age, most unserviced movements will have less than that. It is not COSC certified. I noticed an accuracy of -7 seconds per day.
