New bracelet pin design for Sumo.
SEIKO changed their bracelet pin design for Sumo.
They switched over to common parts in order to cut costs.
The new pin is used by cutting, along with the Link.
It can also be used with the Seiko Shogun bracelet pin. Of course, it has to be cut.
My cheap Nipper doesn't cut well, and I was not able to cut it well like the graph shown in the upper left. I adjusted it with a file.
