Engineer's comment
The internal lubricating oil had deteriorated and accuracy had deteriorated significantly. Since the mainspring was broken and could no longer be operated, a new mainspring was installed.
The malfunction of the crown was caused by mandrel wear, so we replaced it with an aftermarket part that has the same performance as the genuine product.
In addition, the rotor core was also worn out, so we replaced it with an external product as well. After repair, stable accuracy has been restored and the product is safe for daily use.
