Time-Honoured Craftsmanship: Fine Dials in Fascinating Colours
The most striking feature of the new GMT Guilloché is its finely guillochéd dial. This traditional craft involves creating geometric patterns composed of numerous fine lines, meticulously engraved using a guilloché machine. While a machine is employed, it is the skill of the guillocheur that truly brings the motif to life. The artisan must continuously reposition the burin and apply precise pressure to achieve the desired pattern. This process demands intense concentration and superb visual judgment to ensure a consistent, aesthetically pleasing result.
The ultra-fine grooves are polished to a high sheen with a diamond tool, producing a captivating play of light and reflection. This effect is further elevated by the dial colours—matte green on one model and vibrant orange on the other—applied using a special coating. With the intricate guilloché, the dial’s colour nuances change with the light.
Handcrafted hour, minute, and small seconds hands enhance the refined appearance: polished, lance-shaped hands contrast beautifully with the orange dial, while the green dial is paired with steel hands annealed in blue, providing a vivid visual accent.
Stylish and Functional: The Second Time Zone
Both models offer a highly functional complication: a second time zone displayed with elegance and subtlety. A 24-hour scale encircles the dial, marked by an arrow-shaped GMT hand that distinguishes between day and night. Local time is indicated by central hour and minute hands, accompanied by a small seconds subdial at 6 o’clock. A secondary crown at 10 o’clock allows the GMT hand to be adjusted in one-hour increments, both forwards and backwards—ensuring ease of use when travelling across time zones.
The Calibre 100.8: Glashütte Watchmaking at Its Finest
The intricate calibre 100.8 is visible through the sapphire crystal caseback. The movement showcases the hallmarks of Moritz Grossmann’s Glashütte craftsmanship: a 2/3 plate with raised gold chatons, the signature Grossmann ratchet, a separately removable winding unit with pusher mechanism, and a cantilevered balance cock with micrometer screw. The mass-optimised balance adds further precision. A striking interplay of colours from the movement’s finishing details completes the visual impression—underscoring the brand’s dedication to both mechanical excellence and aesthetic refinement.
Limited to just eight pieces per version, each model is housed in a 41mm stainless steel case and reflects Moritz Grossmann’s commitment to artisanal watchmaking and technical sophistication.
