True GMT: time without boundaries

This mechanical complication, known as True GMT, is designed for those who experience time on a global scale. Conceived for movement across continents, it transforms time into a functional tool: the local hour hand adjusts independently in one-hour increments, without interrupting the movement, while the 24-hour hand preserves a constant reference to home time. The bidirectional BK7 glass bezel, with 24 clicks, completes the system, enabling the precise and immediate reading of a third time zone.

The origins of global time

At the dawn of the 20th century, great ocean crossings connected continents and time zones, making it essential to maintain a precise temporal reference. Routes traced on maps became, in turn, coordinates in time. From this need, the GMT function was born: the ability to read local time alongside that of a distant reference point. A principle that today evolves into a system designed for those who move across places, ensuring continuity in time wherever they go.

A play of light on the dial

The soleil finish enhances the surface with dynamic reflections, while the graduated fumé effect creates a depth of color that intensifies toward the edge. The result is a dial that shifts in character with the light and the angle of view. Applied, faceted ingot-style indices are treated with Super-LumiNova BGW9, ensuring optimal legibility even in low-light conditions.

Coordinates of universal time

The finely engraved case back celebrates the adoption, in 1884, of the 24-time-zone system as the global standard, based on Greenwich Mean Time. Surrounding the depiction of the Earth, major cities of the world are marked alongside their respective time zones, allowing the wearer to set the time in a traditional way while preserving the charm of a purely mechanical precision instrument.
