Moritz Grossmann dropped the GMT Guilloche

Moritz Grossmann continues to redefine independent German watchmaking with the introduction of an incredibly exclusive creation: the stainless steel GMT Guilloché in matte green or orange, limited to just eight pieces each worldwide. This stunning timepiece combines masterful engineering, functional elegance, and high-end craftsmanship—proving once again that the Glashütte-based brand remains at the forefront of modern horology.

A Bold Case for Timeless Style

The watch makes an immediate impression with its 41mm stainless steel case, measuring just 11.8mm thick. Its clean, balanced proportions suit both contemporary and traditional tastes. The sapphire crystal is anti-reflective, providing a clear view of the intricate dial. Flip the watch over, and the sapphire display back reveals a handcrafted movement in all its glory. Though refined, the case maintains a robust water resistance, making it practical for everyday wear.

Mechanical Art in Motion

Inside beats the caliber 100.8, a manual-wind movement developed entirely in-house by Moritz Grossmann. It operates at 18,000 vibrations per hour and offers a 42-hour power reserve. Regulated in five positions, this movement exemplifies the brand’s obsessive commitment to precision.

The technical highlights include a shock-resistant Grossmann balance with four inertia screws, a Nivarox 1 hairspring with a Breguet terminal curve, and a lever escapement that ensures stability. Twin fast-rotating barrels, one fitted with a slipping spring, work together to keep the energy flowing smoothly.

Finishing at Its Finest

The movement construction stands out not only mechanically but visually. A pillar-based structure supports a 2/3 plate in untreated German silver, finished with Glashütte striping. Hand-engraved balance and escape wheel cocks, polished bevels, countersinks, and gold chatons elevate the decoration to an art form. A black-polished gold plate surrounds the balance wheel, acting like a mirror and enhancing contrast with a dramatic effect.

GMT Functionality Reimagined

While beauty draws you in, function seals the deal. This watch delivers more than just time. It offers a 24-hour GMT complication displayed via a revolving hand, controlled by a dedicated crown at 10 o’clock. This independent adjustment allows users to shift the second time zone forward or backward at will—a rare and intuitive feature.

A lateral pusher initiates hand-setting and reactivates the movement, a hallmark of Grossmann’s innovative approach to functionality.

A Final Word on Exclusivity

Only eight collectors worldwide will have the opportunity to own this mechanical work of art. From the satin-finished dial’s guilloché texture to the uncompromising attention to detail in every component, the Moritz Grossmann GMT Guilloché in steel stands as a bold farewell to a highly revered complication.

This isn’t just a limited edition—it’s a final statement. A refined, rare creation that celebrates the very best of German watchmaking.
