I spoke to Gerhardt, head technician at VC in New York today (Mon, 27th) about these overseas and winders. He said to set the winder for 1100 turns counter clockwise for dualtime model and 1000 turns clockwise for chronograph. As my Belino's highest setting is 950 turns I'll set it for that and see what happens.
My dualtime as been on the winder now over 24hrs and has NOT lost any of its power reserve. This is a good sign, I will report back at the end of the week.
