Miyota 9075 GMT Movement Released: The Game Changer
Miyota 9075: The GMT Movement That Changes the Game
Citizen's Miyota division has officially released the 9075 GMT movement, a direct competitor to Seiko's NH34 that promises higher accuracy, a slimmer profile, and a true independently-settable GMT hand. The movement has been anticipated by the modding community for over two years, and early reports suggest it delivers on its promises.
Specs Comparison: 9075 vs NH34

Why True GMT Matters
A true GMT lets you set the local hour hand independently while the GMT hand stays on home time — the correct way a traveler's watch works. The NH34 is a "caller GMT" where the GMT hand moves with the hour hand. For modders building travel watches, the 9075 is the technically superior choice.
Parts Ecosystem Impact
The 9075 uses different dial feet and hand sizes from the NH34, meaning a new ecosystem of compatible parts is needed. Early adopters report that dials are already appearing from major aftermarket suppliers, but hand selection remains limited. The movement's thinner profile opens new case possibilities that the taller NH34 stack cannot achieve.
Availability
The 9075 is shipping to watchmakers and modding suppliers as of Q2 2026. Expect the first modded builds to appear in community galleries by late 2026, with a full parts ecosystem maturing through 2027.
Community Verdict
Enthusiasts are excited but cautious. The higher price point and limited parts ecosystem mean the NH34 will remain the default GMT choice for budget builds. The 9075 positions itself as the premium option — worth the cost for builders who want the correct GMT functionality.
