Moritz Grossmann GMT Guilloche Green
Reference: MG-003892
The Moritz Grossmann GMT Guilloche Green encapsulates the magic of global travel in a breathtaking timepiece. Drawing inspiration from the endless green meadows and hidden coves encountered while chasing the sun across continents, the GMT Guilloche Green combines sophisticated aesthetics with the practical functionality of a second time zone. Its matt green dial, adorned with a finely hand-guillochéd pattern, shifts in nuance depending on the light, reflecting the skill of the guillocheur and the heritage of traditional craftsmanship.
The standout feature of the GMT Guilloche is its 24-hour scale encircling the dial, accompanied by an arrow-shaped hand that elegantly indicates the second time zone. This allows wearers to keep track of two time zones at once – perfect for world travellers or those connecting with loved ones across the globe. A separate setting crown at 10 o’clock enables easy forward or backward adjustment of the second time zone in hourly increments without affecting the main 12-hour time display. This ingenious mechanism, driven by an intricate gear system, ensures both time zones remain perfectly synchronised.
Complementing the dynamic dial are handcrafted, lance-shaped steel hands annealed in blue, offering a striking contrast against the green background. The impeccable calibre 100.8 movement, visible through the sapphire crystal caseback, showcases Moritz Grossmann’s hallmark features, including the cantilevered balance cock with micrometer screw, raised gold chatons, and finely hand-engraved balance and escape-wheel cocks. The integrated second time zone mechanism, with its ratchet wheel and spring, exemplifies Grossmann’s mastery of precision engineering.
Each GMT Guilloche Green is housed in a polished 41 mm stainless steel case and paired with a black hand-stitched alligator leather strap. Limited to just eight pieces worldwide, this model is a rare combination of artistry, technical excellence, and exclusivity – a true collector’s piece.
