The Islander Northport Automatic Dive Watch is a technical dive instrument inspired by the maritime heritage of the North Shore of Long Island. Its defining feature is a gradient "ocean blue to white" ripple-textured dial, designed to mimic the water of the Long Island Sound. The dial is equipped with polished silver applied markers and a color-matched 6 o’clock date window, both of which are treated with BGW9 Super-LumiNova for a blue luminous glow. To ensure long-term durability, it features a scratch-resistant sapphire bezel insert that matches the dial's gradient color scheme and is also luminescent.

The watch is constructed with a 40.5mm stainless steel case and a slim 12.5mm thickness, providing a compact profile for a 200-meter diver. A 47mm lug-to-lug distance is paired with negative endlinks on the bracelet to ensure a close fit without overhang on the wrist. The fully brushed stainless steel bracelet tapers from 20mm at the lugs to 16mm at the clasp, which includes a milled 6-position micro-adjust system for fine-tuning the fit. The total weight of the watch on the bracelet is 165 grams.

Internally, the Northport is powered by the Miyota 9015 hi-beat automatic movement, which operates at 28,800 vibrations per hour for a smooth 8-ticks-per-second motion. The movement is a self-winding caliber that also supports hand-winding and hacking for precision time setting, with a 40-hour power reserve. Protection is provided by a flat anti-reflective sapphire crystal and a screw-down crown with the Islander logo.
