When it comes to dive watches, few models have achieved the cult status and legendary reputation of the Seiko Prospex Diver’s Pepsi Automatic Blue Dial Men’s Watch (SKX009K). Known simply as the "SKX009" to watch collectors and enthusiasts, this timepiece represents the perfect balance between professional-grade functionality, everyday versatility, and timeless style. Built to Seiko’s exacting standards, the SKX009K has earned a place as one of the most beloved dive watches in history—and for good reason.
In this article, we’ll dive deep (pun intended) into what makes the SKX009K such a legendary piece. From its rugged construction and reliable automatic movement to its iconic Pepsi bezel and rich legacy, this is a watch that continues to stand tall among both divers and collectors alike.
A Brief History of the SKX009K
Seiko has been a pioneer in dive watches since the 1960s, introducing professional-grade timepieces that combined Japanese precision with robust durability. The SKX series, introduced in the 1990s, quickly became a cornerstone in Seiko’s lineup. Alongside the black-bezel SKX007, the SKX009 distinguished itself with its vibrant blue dial and red-and-blue “Pepsi” bezel.
Over time, it became more than just a tool watch—it evolved into a cultural icon. Praised by professional divers, casual wearers, and serious collectors, the SKX009K earned respect for offering ISO-certified dive capabilities at an accessible price point. Even though production of the SKX line has ceased, its reputation endures, and the watch remains highly sought-after.
Case & Build Quality: Rugged Yet Refined
The 42.5mm stainless steel case of the SKX009K strikes a balance between presence and comfort. Its robust construction ensures it can withstand the rigors of underwater exploration, while its well-proportioned design sits comfortably on most wrists. At 13mm thick, it has the heft of a professional tool watch without being overly bulky.
Seiko equips the watch with a scratch-resistant Hardlex crystal, designed to handle knocks, scrapes, and pressure changes with ease. The screw-down case back and crown further reinforce the watch’s durability, ensuring a watertight seal that contributes to its impressive 200-meter water resistance rating.
The unidirectional rotating bezel is both practical and iconic. Featuring a blue-and-red “Pepsi” color scheme, it allows divers to track elapsed time underwater while lending the watch a striking, sporty aesthetic. The bezel’s firm clicks and precise alignment reflect Seiko’s meticulous craftsmanship.
The Iconic Blue Dial
At the heart of the SKX009K is its deep blue dial, which pairs beautifully with the Pepsi bezel. This combination creates a bold yet versatile look—equally at home on a wetsuit during a dive or on the wrist during a night out.
The dial layout is classic Seiko: large, LumiBrite-coated hands and indices provide outstanding visibility in low-light or underwater conditions. The day-date window at 3 o’clock adds practicality, while the overall design maintains excellent balance and legibility.
Unlike many modern dive watches that lean toward oversized and flashy designs, the SKX009K achieves timeless appeal through its clean, functional layout and subtle color contrasts.
Movement: The Seiko Caliber 7S26
Powering the SKX009K is the tried-and-true Seiko Caliber 7S26 automatic movement. This self-winding mechanism has long been celebrated for its reliability and durability rather than elaborate complications.
21 jewels ensure smooth operation and reduced friction.
A 40-hour power reserve means the watch will keep running even if you set it aside for a day.
The movement beats at 21,600 vibrations per hour, delivering consistent accuracy.
While the 7S26 does not feature hacking seconds or manual winding in its earliest iterations, its workhorse reputation has cemented its place in horological history. Known for requiring little maintenance, this movement can run for decades with proper care—a true testament to Seiko’s engineering philosophy of creating watches “for everyone, everywhere.”
Professional Diving Features
The SKX009K isn’t just about looks—it’s a professional-grade dive watch, certified under ISO 6425 standards. This certification guarantees its ability to handle underwater pressures and environments safely.
Key diving features include:
Unidirectional rotating bezel for measuring dive times accurately.
200-meter water resistance, suitable for recreational and professional diving.
Screw-down crown and case back to prevent water ingress.
LumiBrite-coated hands and markers for exceptional readability in dark or underwater environments.
For divers, these features provide the confidence needed when venturing into the depths. For non-divers, they ensure a rugged, dependable watch that can handle everyday life with ease.
Strap Options & Comfort
The SKX009K typically comes with a durable black silicone strap that’s comfortable for long wear, even in wet conditions. The strap is fitted with a secure pin buckle, ensuring it stays in place whether you’re diving, swimming, or simply going about your day.
However, one of the joys of the SKX009 is its versatility with aftermarket straps. Enthusiasts often pair it with NATO straps, stainless steel bracelets, or leather bands, allowing the watch to transition from sporty to casual to even semi-formal settings.
Why the SKX009K is a Collector’s Favorite
The SKX009K’s enduring appeal lies in its combination of:
Heritage: A continuation of Seiko’s pioneering dive watch legacy.
Affordability: Professional features at a price point accessible to many.
