The Seiko NH34A is a new entry-level automatic caliber with unique features. In fact, there are no other equally reliable movements that make it possible to offer a GMT watch within everyone's reach. The Seiko NH34A / 4R34 is at the core of our most recent project, the new Nereide GMT 39, and its technical characteristics have allowed us to create a top-level automatic GMT in terms of component quality, while keeping it affordable.
