Master series, the only version consistent with the authentic
About the movement:
Automatic winding system: YL version of the movement is a two-way winding, while other versions of the market are single-up winding
Automatic winding noise: The YL version has only a slight chain sound (same as the original product), while other versions in the market are the noise generated by the automatic rotor rotating the friction bottom cover and the movement deck
The structure of the movement: the YL version of the movement is demolished by disassembling the genuine movement of the same model, and the structure is basically the same. The matching of the movement parts is more than 95%, while the other versions of the movement are modified with the Japanese 9015 movement. Come, the structure is different
Movement shock absorber: The Yl version of the movement shock absorber is the same as the original KIF shock absorber, while the other versions on the market are the original ecological shock absorbers of the Japanese 9015 movement.
After repeated testing ~ the stability is comparable to the original!
