GMT MOD

The GMT MOD collection brings together Seiko mod watches with an NH34 GMT automatic movement. Its additional 24-hour hand helps you keep a second time alongside local time.

GMT function or chronograph?

A GMT adds another 24-hour time display, while a chronograph measures intervals. Compare TONA MOD if stopwatch timing and subdials matter more. If you want time and date without a second time zone, DATE MOD is the closer alternative.

Choose the dial and bezel for readability

Red-and-blue, blue-and-black, green-and-black, brown-and-black and single-colour versions give GMT models different contrast. Compare the dial, 24-hour display and bezel by how quickly you can read them day to day.

Compare bracelet and configuration

Treat the bracelet and case back as part of the individual model, and check the product page rather than assuming them from the bezel colour. That lets you choose the GMT function first, then the version that suits your wrist and style.

Compare two GMT models

GMT Mod Pepsi combines a red-and-blue ceramic bezel with a 40 mm case. GMT Mod Silver Horizon instead uses a silver dial. Both example models list NH34 GMT and use a Jubilee bracelet with a clear case back.

From style to the right watch

The GMT collection pairs the NH34 function with different dials, bezels and bracelets. Our model overview places GMT, automatic and chronograph functions side by side; each product page describes the model configuration.
