SKX007 Seigaiha: Luminous Matte Silver

A distinctive SKX007-based GMT custom build combining the classic proportions of the iconic SKX platform with the clean aesthetic of the Seiko SSK033 GMT.

At the heart of the build is a genuine Seiko SSK033 GMT OEM dial, paired with polished silver Cathedral-style hands featuring C3 lume. A polished blue and silver GMT hand adds a subtle contrasting accent while providing independent 24-hour indication.

The brushed silver GMT chapter ring and slim brushed silver dual-hour luminous bezel create a cohesive monochromatic appearance, while the sapphire crystal provides enhanced clarity and scratch resistance.

Powering the watch is the reliable Seiko NH34A GMT automatic movement, featuring an independently adjustable GMT hand and a matte silver date wheel with black numerals.

The watch is housed in a matte silver SKX007 case, complemented by a matching slim matte silver caseback and chunky matte silver screw-down crown with an engraved “S”. The slim component configuration keeps the overall thickness to approximately 12.8mm while retaining the robust proportions of the SKX platform.
