This replica GMT-Master 126718GRNR 40mm features a Tiger Iron stone dial set inside a full 18k yellow gold case, placing it among the most visually unconventional references in the GMT-Master II catalog. Tiger Iron is a sedimentary stone composed of tiger’s eye, red jasper, and hematite, producing bands of gold, red, and metallic grey that differ from dial to dial. No two examples share the same pattern, which makes each 126718GRNR functionally unique despite sharing identical case and movement specifications.

Rolex paired the Tiger Iron dial with the green-and-black “Sprite” bezel, connecting the warm stone tones to the green ceramic half through a shared earth-tone palette.

Design & Finishing

Stone dials occupy a specific category within the catalog, reserved almost exclusively for precious-metal cases. The Tiger Iron surface is cut and polished to a mirror finish, then drilled precisely for the applied hour markers. Because the stone is a natural material, the banding pattern runs at unpredictable angles across the dial face, creating a visual texture that painted or lacquered dials cannot reproduce. The gold Maxi-style markers and Mercedes hands sit on top of this geological surface, producing a contrast between organic pattern and mechanical precision. For the rose-gold alternative with the same stone treatment, see the full GMT-Master collection where both gold variants are listed side by side. To compare a different precious-metal approach, the complete GMT-Master II set shows every available configuration in one view.

On the Wrist

The full-gold case and bracelet give the 126718GRNR a substantial wrist presence at 40mm. The Tiger Iron dial draws attention in a way that standard sunburst or matte finishes do not, and direct sunlight activates the reflective hematite bands within the stone. The green-and-black bezel keeps the watch connected to the GMT-Master sports lineage despite the exotic dial material. For buyers who want a GMT-Master that functions as a conversation starter beyond the standard color options, this replica GMT-Master 126718GRNR 40mm delivers that stone-dial, full-gold combination in its most striking form.
