1. Is this a genuine MIYOTA minute wheel?
Yes. It is a Japanese factory-original part for the 82S7 movement, not a copy.
2. What are the symptoms of a damaged minute wheel?
Symptoms: the crown feels too loose (no resistance) or too tight when setting time; the minute and hour hands do not align after setting; hands wobble or timekeeping is inaccurate.
3. What should I pay attention to during installation?
The minute wheel sits above the center wheel. Ensure proper meshing with the intermediate wheel and hour wheel. Follow the MIYOTA technical guide. Professional installation is recommended.
4. Does this part fit other MIYOTA calibers like 8215?
