Automatic coastal GMT

MERIDIAN

A travel watch that keeps its connection to the water. Local time stays immediate while a slim internal 24-hour scale follows home across every longitude.

Two places. One glance.

Travel time, brought inside.

MERIDIAN places its complete 24-hour scale on a single-color inner ring, leaving the broad brushed-steel bezel uninterrupted. The result reads like a four77 watch first and a GMT second.

01 · GMT

Home stays visible.

A high-contrast arrow hand tracks a second time zone against the internal 24-hour scale without competing with the matched sword hands for local time.

02 · CASE

Nautical by design.

A brushed 40mm Nautilus-style case gives MERIDIAN a compact, square coastal-sport silhouette, with integrated strap geometry and its crown at three o’clock.

03 · WATER

Ready for the everyday.

A wave-textured dial, shared six o’clock emblem, sapphire crystal, and screw-down crown carry the concept from the workbench into daily wear.

Working specification

Built around a proven GMT.

The concept uses the NH34 and an off-the-shelf 40mm case to make the route to a functional prototype realistic while preserving MERIDIAN’s broad bezel and internal GMT display.

Four routes around the same world.

Deep Current establishes the collection connection. Sunward brings warmth, Signal emphasizes utility, and North Sea reduces the concept to cool monochrome with a single ice-blue accent.
