Designed to capture the sublime experience of peering toward the ocean's surface from the depths, the dial features a dynamic ripple-wave texture with a vertical dégradé gradation transitioning from bright turquoise cyan at 12 o'clock to deep oceanic navy at 6 o'clock. Bold, oversized applied circular and baton hour indices line the perimeter, accompanied by the iconic split-wedge marker at 12 o'clock—a hallmark design trait that originally earned the silhouette its \"Sumo\" nickname. Every hour marker is generously filled with Seiko’s proprietary LumiBrite compound, which glows in contrasting blue and green hues to guarantee instant legibility in pitch-black marine environments. The prominent arrow-style minute hand is highlighted in high-visibility cyan blue, matching the critical first 15-minute decompression timing sector on the bezel insert. A date calendar aperture sits neatly at 3 o'clock, balanced by the official PADI collaboration logo displayed above 6 o'clock. Framing the dial is a unidirectional 120-click rotating dive bezel fitted with a scratch-resistant, mirror-polished navy blue ceramic insert with an engraved 60-minute scale and a luminescent pip at 12 o'clock. Beneath its tailored exterior, the watch is powered by Seiko’s high-grade in-house Calibre 6R35 Japanese automatic mechanical movement, engineered and manufactured at Seiko’s dedicated horological facilities in Japan. \u003cspan class=\"citation-909\"\u003eOperating at a steady frequency of 21,600 vibrations per hour (3 Hz), this 24-jewel self-winding caliber delivers an extended
