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.

Community
Owners widely praise the Seiko SKX009 as a desirable daily beater and a favored summer watch for its looks, comfort, and tool watch feel, with one owner noting an inexplicable quality that makes them choose it over more accurate watches. The unique Arabic date wheel and red strap are specific points of appreciation, and it was a forum favorite for first-time diver purchases. Some owners find the stock bezel insert "hideous" due to its second markers and Pepsi colors, while others chose the watch specifically for it. The Seiko SKX009 is noted as having been discontinued. On balance, owners rate the Seiko SKX009 highly for its enduring tool watch appeal and distinctive aesthetic, making it a beloved, albeit now discontinued, choice.
