Take one Seiko SKX007J (or K*),
one set of Seiko SKZ211K hands (we’ll see what these look like shortly) and proceed as follows:
1. Remove bezel and bezel click spring
* the K variant of the SKX007 likely emerges from the same factory as the J variant and that factory may or may not be located in Japan. The K probably refers to different destination market rather than implying that models so designated are somehow inferior to those with the J.
