The Moritz Grossmann GMT Guilloche is a celebration of global exploration and fine German watchmaking. Inspired by the colors of nature and the rhythm of travel, this dual time zone watch is available in two striking dial variants: matte green, evoking serene meadows and hidden coves, and vibrant orange, reminiscent of the glow of a setting sun.
Dual Time Functionality
Designed for the modern traveler, the GMT Guilloche features a 24-hour time zone ring encircling the dial. A distinctive arrow-shaped hand tracks a second time zone, offering intuitive day-night orientation. Local time is displayed via central hour and minute hands, with a small seconds subdial at 6 o’clock. A dedicated crown at 10 o’clock allows seamless adjustment of the second time zone without affecting the main time.
Masterful Craftsmanship
Each dial is hand-engraved using the traditional guilloché technique, creating intricate geometric patterns that shimmer with light. The green dial is paired with blued steel hands, while the orange dial features polished steel hands—both handcrafted in Glashütte.
Engineered for Precision
Inside the watch beats the calibre 100.8, a manually wound movement crafted in-house and regulated in five positions. It features 253 components, 26 jewels, and signature Grossmann innovations including the 2/3 plate with raised gold chatons, cantilevered balance cock with micrometer screw, and a separately removable winding mechanism. The second time zone mechanism is seamlessly integrated on the dial side, ensuring precision and harmony.
Limited Edition
Encased in stainless steel and fitted with a hand-stitched black alligator leather strap, each GMT Guilloche model is strictly limited to 8 pieces worldwide, making it a rare collector’s item.
