Seiko

Seiko's legendary budget automatic caliber that powered the original Seiko 5 line and SKX diver series for decades. Lacking hacking and hand-winding, it is mechanically simple with just 21 jewels, but this simplicity contributed to its remarkable durability and low maintenance requirements. Now discontinued in favor of the NH35/4R35, the 7S26 remains one of the most iconic and beloved movements in affordable horology.
