NMK959 N4 GMT Tool Case Bundle: Steel Finish
Meet our NMK959 N4 GMT Tool Case Bundle in Steel Finish: all the presence and attitude of a chunky tool watch, with the added utility of a dedicated second time zone. The brushed steel bezel is engraved with a minimal 24-hour scale, framing your dial like a piece of instrument hardware and giving the watch a purposeful, travel-ready look that still feels clean and modern.
At 40mm wide with a 49mm lug-to-lug and straight drilled lugs, it wears planted and balanced, offering plenty of dial real estate for bold GMT handsets and legible, travel-focused layouts. The oversized 8mm screw-down crown is easy to grip even with wet or gloved hands, keeping the same rugged, military-inspired feel while making quick time and timezone adjustments an absolute breeze.
