Seiko GMT: Golden Emerald

A distinctive gold GMT custom build combining the classic proportions of a 40mm Submariner-style case with a rich matte green dial and contrasting black and gold details.

At the heart of the build is a custom matte green GMT dial with BGW9 lume, paired with polished gold Mercedes-style hands and a contrasting polished green GMT hand. The combination of green and gold creates a bold yet cohesive aesthetic, while the black GMT bezel insert with gold numerals provides a clear 24-hour scale.

Powering the watch is the reliable Seiko NH34A GMT automatic movement, providing an independently adjustable GMT hand for tracking an additional time zone. A white date wheel with black numerals is positioned beneath the sapphire crystal's Cyclops magnifier for improved legibility.

The brushed and polished gold case is finished with a polished gold screw-down crown and exhibition caseback. A matching brushed and polished gold Oyster bracelet with micro-adjustment clasp completes the full-gold appearance.
