The Prospex PADI Special Edition SPB325 automatic dive watch commemorates the joint efforts of Seiko, the manufacturer of Japan’s first diver’s watch, and PADI, the world’s leading scuba diver training organization, to protect the ocean for future generations. This new model is a reinterpretation of a classic Seiko design with modern materials that continues a rich legacy of innovative, high-intensity timepieces and marks a new era of collaboration between Seiko and PADI.

Seiko began to manufacture dive watches during the 1960s. These early landmark models earned a reputation for durability, reliability and capability through several Japanese expeditions to the Arctic and Antarctic. These dependable divers would eventually lead to the creation of Seiko’s Prospex line—high-quality, hard-wearing tool watches designed to meet any challenge with technological excellence and style, with a continual dedication to improving reliability and safety.

Better Together

Seiko and PADI previously collaborated on several Prospex dive watches, which reinforced the brands’ shared commitment to high-quality dive equipment and safety. The SPB325 commemorates a significant milestone in the brands’ relationship as they partnered together toward another critical issue facing the dive community: marine conservation.

In 2021, this developed into a mutual dedication to ocean stewardship when Seiko became an official sponsor of PADI’s Marine Debris Program—a shared conservation framework developed by PADI and the PADI AWARE Foundation to address critical ocean challenges through measurable conservation goals.

This program harnesses the collective power of scuba divers worldwide to combat marine debris. At its heart is Dive Against Debris, the PADI AWARE Foundation’s flagship initiative, which empowers divers to remove waste from underwater environments and report their findings. Since its launch in 2011, this citizen science movement has built the world’s largest underwater marine debris database—owned and managed by the PADI AWARE Foundation—with over 90,000 divers reporting more than 2.5 million pieces of debris and aiding over 35,000 entangled marine animals to date. Seiko’s support helps sustain and expand this impact by funding training, events, program maintenance and data validation, ensuring the program continues to drive meaningful ocean change.

Seiko’s contributions enable action at the local, national and international levels. Other operational expenses supported by Seiko include the PADI AWARE Community Grant program, which provides much-needed financial resources to on-the-ground marine debris removal and prevention initiatives spearheaded by local PADI dive centers and resorts.

To Mark the Occasion

The SPB325’s 45 mm stainless-steel case is inspired by Seiko’s iconic 1968 hi-beat diver’s watch. It is treated with a super-hard coating for enhanced durability. Outfitted with a screw-down crown and caseback, it is waterproof up to 200 meters/660 feet. The 24-jewel automatic movement has a frequency of 21,600 vibrations per hour for extreme accuracy and a 70-hour power reserve. The included blue silicone strap is both practical and comfortable. It dries quickly and offers easy fitting over bare wrists and a variety of different diving wetsuits.

A black unidirectional timing bezel provides a reliable method for measuring elapsed dive time underwater. Made of scratch-resistant ceramic, it has a mirror-like shine when it catches the light. The black dial contrasts readily against the large LumiBrite-coated hands and markers for easy, instant legibility in all conditions. It includes a date window at the 3 o’clock position.

PADI’s name adorns the dial just above the 6 o’clock position, and the globe-patterned background references PADI’s iconic logo—a scuba diver carrying a torch illuminating the globe. The watch’s darker color palette provides a sense of sophistication, while its bright-blue accents, dive styling and subtle nods to the world’s premier dive-training agency maintain a sporty attitude that makes it easily transition from the office to the dayboat.

Seiko’s deeper involvement in PADI’s Marine Debris Program reflects a natural progression of its mission to support divers in exploration to actively protect the environments that divers explore. The Prospex PADI Special Edition SPB325 is a wonderful tribute to this new era of collaboration and conservation.

A PROGRAM FOR SUCCESS PADI’s Marine Debris Program includes a variety of initiatives aimed at ridding the ocean of waste. Dive Against Debris empowers divers on the individual and community levels to clean up the underwater world. The debris removed by divers is cataloged in a Global Marine Database, which provides critical information to inform environmental legislation and conservation efforts. PADI AWARE Community Grants provide funding to various organizations, including PADI Dive Centers and marine conservation groups across the world. These grants support cleanup events, public outreach and other conservation projects. The Marine Debris Removal Program also trains divers to safely remove entangled marine life, improve waste management and advocate for plastic pollution policies.
