1. Is this a genuine MIYOTA balance wheel?
Yes. The product clearly states “Genuine MIYOTA” and “Made in Japan”, meaning it is an authentic factory part from MIYOTA (Citizen Japan), not a third-party copy.
2. Which movements is this balance wheel compatible with?
It is designed specifically for the MIYOTA 9015 automatic caliber. Different variants of the 9015 may have slightly different dimensions – verify with the parts diagram or consult a watchmaker. Not compatible with ETA, Sellita, or other brands.
3. Will my watch keep correct time after replacing just the balance wheel?
After replacing the balance wheel, you must also inspect the hairspring (replace if damaged) and perform dynamic balance and timing regulation (via regulator or balance screws). Professional watchmaker assistance is strongly recommended.
4. What should I pay attention to during installation?
Balance wheels are extremely delicate. Avoid shocks, static, and contamination. Carefully handle the shock protection system and ensure both pivot tips are intact. Do not attempt without proper training.
5. Is there any warranty?
As a brand new genuine part, it typically comes with the supplier’s quality guarantee. Please check with your seller. Damage caused by improper installation is not covered.
