Islander Hudson “Harpoon Diver” ISL-305 – Degrading Sea Green Dial – 200M Automatic

The Islander Hudson “Harpoon Diver” ISL-305 is one of Islander’s most distinctive premium dive watches, combining a vintage 1970s-inspired case with a creative shark-and-ocean theme, a high-beat Miyota 9015 automatic movement, sapphire components, and serious 200-meter dive-watch capability.

The centerpiece is the unusual degrading sea green dial, featuring a subtle pressed shark pattern that becomes visible as the watch is viewed from different angles. Boat-hull-shaped hour markers appear to pull toward the center of the dial, while the rope-pattern chapter ring adds another nautical detail. Even the dial itself incorporates lume, producing a soft background glow in darkness. (Long Island Watch)

The watch earns its “Harpoon Diver” nickname from its specially shaped minute hand. The counterbalance of the seconds hand incorporates the silhouette of a swimming shark, continuing the ocean theme without overwhelming the design. At 6 o’clock is another particularly unusual feature: a luminous date display, an Islander first when the Hudson was introduced. (Long Island Watch)

Inside is the highly regarded Miyota 9015 automatic movement, a slim, high-beat Japanese caliber offering automatic winding, manual winding and hacking seconds. The 9015 operates at 28,800 vibrations per hour, giving the seconds hand a smoother sweep than the lower-beat movements commonly found in watches at this price level.

The stainless-steel case measures a very wearable 40mm in diameter and 47mm lug-to-lug. Case thickness is just 12.1mm excluding the crystal, or approximately 13.4mm including it. A vintage-inspired box sapphire crystal with internal anti-reflective coating provides excellent scratch resistance while maintaining the retro profile of the watch. (Long Island Watch)

Surrounding the dial is a 120-click unidirectional dive bezel fitted with a curved luminous sapphire insert color-matched to the sea green dial. Look closely at the red bezel triangle and you'll find yet another detail—a hidden shark dorsal fin. (Long Island Watch)

The coin-edge screw-down crown helps provide 200 meters of water resistance and even features a luminous Islander logo. Flip the watch over and the shark theme continues with a custom screw-down caseback depicting a shark breaching the water and the playful “HELP!!! SHARK” engraving highlighted in red. (Long Island Watch)

The Hudson is fitted to a brushed stainless-steel mesh bracelet with quick-release spring bars. It measures 20mm at the lugs and tapers to 18mm at the clasp. A tool-free micro-adjustment system makes it easy to fine-tune the fit throughout the day, with additional shark-head detailing incorporated into the clasp and extension mechanism.

The ISL-305 Hudson Harpoon Diver has far more personality than the typical automatic diver. Between the sea green shark-pattern dial, harpoon minute hand, luminous date, luminous sapphire bezel, glowing crown logo, shark-themed caseback and Miyota 9015 movement, there are small details to discover everywhere—while underneath all of that character is a genuinely capable 200M automatic dive watch.
