Islander NH34

The NH34 is an automatic GMT caliber manufactured by Islander, based on the Seiko NH34. It features a dedicated GMT hand that completes one rotation per 24 hours, allowing tracking of a second time zone. The movement includes manual winding and hacking seconds, operates at 3 Hz, and provides a 41-hour power reserve. It is not an in-house movement. The caliber remains in production and is used in Islander GMT models such as the ISL-12.
