Who it's for
Travel-watch buyers who want an affordable automatic GMT with Islander’s Long Island-themed JFK styling and 200m water resistance.
Before you buy
- 42mm case is larger than many dress GMTs
- NH34 is an affordable automatic GMT, not a high-end flyer GMT caliber
- Cloud dial and Pepsi bezel are intentionally playful
- 200m water resistance is useful, but Long Island Watch’s general manual does not treat 200m dive-style watches as ISO 6425-rated scuba divers
- This record tracks ISL-206 specifically
FAQ
Is the JFK GMT automatic or quartz?
The JFK GMT is automatic. The Seiko NH34A winds itself from the motion of your wrist, so it needs no battery. A full wind holds roughly 40 hours, so it keeps running overnight off the wrist; left longer it stops and restarts once you wear or hand-wind it.
What movement does the JFK GMT use?
The JFK GMT is powered by the Seiko NH34A from Seiko Instruments, an automatic caliber with 24 jewels, a 40-hour power reserve, and a 21,600 bph beat rate. Being automatic, it winds from the motion of your wrist and needs no battery.
Does the JFK GMT have a date?
Yes — the JFK GMT has a date display on the dial. The date advances automatically as the movement runs, so the current day of the month is always visible at a glance, and you can set it from the crown after the watch has been left to stop.
How water resistant is the JFK GMT?
The JFK GMT is rated to 200 m. That is true dive territory: fine for swimming, snorkelling and recreational scuba diving, as well as all daily wear. Whatever the rating, avoid operating the crown or pushers underwater, and have the gaskets checked periodically to keep it reliable.
What movement does the Islander JFK GMT use?
The official ISL-206 page lists the Seiko NH34 automatic GMT movement with hand winding, hacking, and roughly 40 hours of power reserve.
Can it track more than one time zone?
Yes. The GMT hand and 24-hour inner ring track a second zone, and the bi-directional 24-hour bezel can be rotated to reference another offset.
Does the date need correction?
Yes. Like most simple date watches, the date advances daily but needs manual correction after February and 30-day months.
How should I treat the 200m rating?
Long Island Watch lists 200m water resistance, but its general manual says 200m dive-style watches are not ISO 6425-rated divers and are not recommended for SCUBA except as a backup to proper dive equipment.
