I baught a "Breitling" in a fleemarket recently for 30 Kr (4$) all the 4 buttons were totally jammed but with something like dry tar but it was ticking. After cleaning with ultrasound and SUN dishwasher powderI got the buttons working again. The buttons 2,4 and 10 gives a function but the 8 button gives no functionality, what should be the function ? I can´t get any sound/chime out of it, is it some trick to put the sound/chime on? Anyone have a usermanual for this Watch ?
