I am writing to the experts here who could better explain the difference between what ETA describes as its 'entry-level composite' ETA F06.411, found in the Certina DS Action, and the 'high-end brass' ETA 955.652, sold as the Breitling SuperQuartz calibre 74.
I have been looking through the ETA documents trying to understand what the main difference is that makes one 'high-end' and the other entry-level. My main qualm is that the F06.411 is sold as 'replaceable' rather than repairable. With my limited knowledge of quartz movements, I understand some cheaper movements are designed to be disposable. I would like to think that the movement in my timepiece can be repaired long in the future, and last the long haul. If the movement is designed to be wholesale replaced in the future, that immediately turns me off.
Besides the obvious i.e. 3 jewels vs 7, and the much larger 3 volt battery in the 955.652, can someone please clarify the differences between the two movements in terms of quality and construction?
