The Traveler's watch
Everything originates from an absolute reference: the Greenwich meridian, the zero point from which time zones are defined. From this need comes the GMT function, designed to maintain a constant connection between different places. A dedicated hand, rotating over 24 hours, works alongside local time and allows the simultaneous reading of a second time zone.
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.
Technical specifications
The Nereide GMT is designed to ensure durability and reliability in any environment. Water resistant to 10 ATM, it safely accompanies everyday use and aquatic activities, maintaining solidity and comfort on the wrist. A robust construction, designed for those traveling between different destinations, where precision and versatility are essential.

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.

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.

Ergonomics in every detail
The 39 mm diameter, 45.5 mm lug-to-lug distance, and 11.9 mm thickness define a precise balance between presence and compactness. The slim profile and sculpted lugs ensure a controlled fit, sitting securely on the wrist without excess. A carefully calibrated construction in which every measurement is designed to deliver stability, comfort, and a constant sense of lightness.

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.
