On another forum there has been considerable debate about whether servicing Asian 7750 as a preventive measure, or just waiting and see how it goes.
Since when Ziggy said that lacking of service does not necessarily make for a permanently damaged movement (it's not like a car running out of oil, he said) most members seem headed towards not have it serviced, especially if the cost of the watch (or of the movement) is not sensibly higher (say, 3x and up) than the cost of servicing it.
If this applies to Asian 7750, let you figure to ETA...
