Seiko SKX009, SKX175 – Iconic Dive Watches

Updated February 2026

The Seiko SKX009 (and its North American counterpart, the SKX175) remains one of the most significant dive watches ever produced. While it was officially discontinued years ago, its presence in the watch community is as strong as ever in 2026. In this review, we look back at why this watch became a legend and how it stacks up against its modern successors.

The History of a Legend

Launched in 1996, the SKX009 was the “Pepsi” sibling to the black-bezeled SKX007. For over two decades, it served as the gateway drug for countless watch enthusiasts. It wasn’t just a “good for the money” watch; it was a legitimate tool watch with ISO 6425 certification, meaning it was a real-deal diver capable of handling the depths.

The Bezel and Case

The 42.5mm stainless steel case is famous for its “chunky” but wearable ergonomics. The crown sits at 4 o’clock, protected by integrated guards—a hallmark of Seiko diver design. The “Pepsi” bezel (red and blue) is synonymous with the SKX009, providing a pop of color that fades beautifully over years of use.

The Movement: 7S26

Inside the SKX009 beats the 7S26 movement. By 2026 standards, it’s a bit of an antique. It doesn’t hack (the seconds hand doesn’t stop when you pull the crown) and it doesn’t hand-wind. However, it is legendary for its durability. Many owners report their SKX running for 15+ years without a single service. It is the definition of “set it and forget it.”

The Successors: SRPD and SSK

Since the SKX’s departure, Seiko has filled the void with the Seiko 5 Sports (SRPD) line and the GMT (SSK) series. While these modern versions lack the 200m ISO rating (moving to 100m water resistance), they offer significant upgrades: hacking, hand-winding, and a massive variety of colorways.

If you want the SKX look with modern reliability and better movement specs, the SRPD is the way to go. If you need the GMT functionality, the SSK series has taken the watch world by storm.

Final Verdict

In 2026, the SKX009 is more than just a watch; it’s a piece of horological history. If you can find one in good condition, buy it. But for daily wear, the modern SRPD and SSK lines provide the same iconic aesthetic with the conveniences of a modern mechanical movement.
