The radial teeth are for hte seconds register, and the other (which is simple and doesn' take away significant torque from the train) for the minutes register. -
The original 6139A manual is very clear in how to disassemble and how to assemble ...... step-by-step. However I haven't seen the 3169B manual, even in the Japanese version around, which clearly highlights the difference in center-wheel. 6139A Seiko Technical Guide.pdf 6139_A.pdf 6139A.pdf 6139b.pdf 6139B repair guide jp.pdf -
