Islander Bayport ISL-310 – Maroon Wave Dial – 200M Automatic Dive Watch

The Islander Bayport ISL-310 is a beautifully proportioned automatic dive watch featuring a distinctive maroon wave-pattern dial, premium enthusiast-level specifications, and an extremely wearable 40mm stainless-steel case.

The centerpiece is the richly textured maroon dial, featuring a repeating wave pattern that creates impressive depth as it catches the light. Partially skeletonized hands and updated hour markers give this generation of the Bayport a more refined, contemporary appearance while maintaining excellent dive-watch legibility. (Long Island Watch)

Power comes from the proven Seiko NH35 automatic movement, featuring self-winding, manual winding and hacking seconds, along with approximately 40 hours of power reserve. A date window is neatly positioned at 6 o'clock. (Long Island Watch)

The stainless-steel case measures a highly versatile 40mm in diameter, 48mm lug-to-lug and 13.5mm thick. Islander pairs it with an H-link stainless-steel bracelet featuring negative end links, allowing the bracelet to wrap naturally around the wrist for increased comfort. (Long Island Watch)

Protecting the dial is a scratch-resistant flat sapphire crystal with internal anti-reflective coating. Surrounding it is a 120-click unidirectional bezel with a sloped ceramic insert. The bezel insert is treated with C3 Super-LumiNova, complementing the generously lumed hands and hour markers for excellent nighttime visibility. (Long Island Watch)

A screw-down crown and solid caseback help provide 200 meters of water resistance, giving the Bayport genuine dive-watch capability rather than simply dive-inspired styling. (Long Island Watch)

The solid stainless-steel bracelet uses screwed links for easy sizing and includes a particularly useful tool-free ratcheting micro-adjust clasp, allowing the fit to be fine-tuned directly on the wrist. (Long Island Watch)
