Hi! I have Hamilton Below Zero Chrono with ETA 7750. Automatic day change works without problem, but automatic date change is broken. Is it possible to change only broken part for date change and what cost of repair should I expect? All other functions of the watch works fine, only automatic date change is broken. Thank you in advance!
If only the date change wheel is worn down (at 0:35 the brass colored wheel a the bottom) replacement should be relatively low cost. Otherwise, you might need a full service.
Almost 7750 movements are held by the metal movement holder. Sometimes very tightly held by the holder, then you slightly turning the holder by pair of tweezers.
늦게 확인해서 죄송합니다. 해당제품은 bergeon 6436 입니다. 하지만 지금은 bergeon 7010 을 쓰고 있습니다. 차이는 6436은 폴리스티렌 재질로 무른편이며 개인적으로는 쉽게 부러졌습니다. 또한 한쪽끝이 그냥 원통으로 마감되어있습니다. 7010은 폴리아미드 재질로 더 강하고 한쪽끝이 플랫하게 마감되어 있어 좀 더 다용도로 사용할 수 있습니다.
Thanks for watch my video. It was extracted from the genuin MIDO watch. As you know, there are some differences between ETA 7750 and China's copy product. What was the basis for judging it as a copy?
