Description:
7S26 is one of the most popular modern automatic watch movements from Seiko. Other closely-related members of this 7S family include the 7S35, 7S36, and 7S55, along with letter revisions of the 7S26.

The 7S26 family was introduced in 1996 as a mainstream automatic watch movement, replacing the Seiko 7002 in many cases. Although earlier Seiko calibres featured quickset date, the 7S26 adds a counter-clockwise quickset day feature as well.

It is almost totally different from earlier Seiko 7002 series calibres, though it does continue the "Magic lever" bi-directional winding design. Rather than using a dedicated winding bridge to locate the lever, the 7s26 family locates it with a brass bushing on one side and the rachet wheel on the other. The keyless works have been relocated from the top plate to the bottom plate, making it easier to service these components from the back plate rather than removing the entire works. The two added jewels, compared to its predecessor, support the third wheel and escape wheel.

This family is non-hacking and not capable of hand winding, unlike its replacement, the Seiko 4R35 family.
