Introducing Seiko Launches Three Stunning Diving Watches

Seiko’s dive watch legacy dates back to 1965, when the brand released its very first diver’s timepiece, a model that laid the groundwork for decades of underwater innovation. Over the years, the Japanese watchmaker has strengthened its reputation not only through technical advancements but also by forging lasting partnerships, most notably with the Professional Association of Diving Instructors (PADI). This long-standing collaboration continues in Seiko’s latest Prospex releases, which include 2 new diver’s watches in green and an additional blue SRPL51.

Leading the new lineup is the SPB501 Diver’s Watch 1965 Heritage PADI Special Edition. This model pays homage to Seiko’s very first dive watch with a compact 40mm stainless steel case, a thickness of 13mm, and a lug-to-lug length of 46.4mm. Its silhouette may nod to the past, but the execution is thoroughly modern. Alongside it are two additions to the brand’s popular “Samurai” sub-series, the emerald green SRPL53 PADI Special Edition and the matte blue SRPL51, a standard production model. These Samurai designs come with slightly larger cases, measuring 41.7mm in diameter, 12.3mm thick, and stretching 49.5mm from lug to lug. Each model maintains a robust stainless steel build that reflects Seiko’s commitment to rugged performance.

As expected from serious dive watches, the water resistance ratings meet professional expectations. The SPB501 offers 300 meters of water resistance. Meanwhile, the SRPL51 and SRPL53 are both rated to 200 meters.

The SPB501 and SRPL53 share an emerald green gradient dial that darkens toward the bottom, an artistic nod to how colors fade in the depths of the sea. The surface features a textured ocean-inspired pattern, and both models are equipped with prominent applied indices, a discreet date window between 4 and 5 o’clock, and a rich coating of Seiko’s LumiBrite for superior readability in low light. A key design difference lies in the branding layout, the PADI logo appears prominently on the lower half of these dials, pushing the Prospex logo to the upper portion just beneath the Seiko name.

In contrast, the SRPL51 introduces a matte blue dial and bezel, continuing the angular Samurai aesthetic but with a cleaner, more traditional layout. With no PADI insignia to accommodate, the Prospex logo remains in its usual position near the bottom of the dial. The hands and indices across both Samurai models maintain a bold design language, with a spear-like hour hand, sword-shaped minute hand, and a luminous-tipped seconds hand.

Beneath the caseback of the SPB501 ticks Seiko’s in-house Caliber 6R55. This automatic movement operates at 21,600 vph (3Hz), and offers a 72-hour power reserve. The SRPL53 and SRPL51 are powered by the Caliber 4R35, another automatic movement known that beats at the same frequency, and delivers a power reserve of 41 hours. 

The SPB501 stands out further thanks to its upgraded strap configuration. It comes on a three-row stainless steel bracelet coated for enhanced scratch resistance and features Seiko’s latest clasp, which combines a six-step tool-free micro-adjustment system with a wetsuit extension. Seiko also includes a secondary Seichu fabric strap, crafted from upcycled fishing nets. On the other hand, the SRPL53 and SRPL51 are fitted with a standard stainless steel bracelet secured with a folding clasp and safety lock. 

As for pricing, the SPB501 is priced at €1,700 ≈ AED 7,300, and the SRPL53 comes in at €670, ≈ 2,900 while the matte blue SRPL51 is priced at €650 ≈ AED 2,800.
