GMT, the traveler’s watch
GMT is the acronym for Greenwich Mean Time, which is the local time of the zero meridian of the homonymous London district. The GMT module consists of an additional hand, with an arrow-shaped tip, which completes one revolution every 24 hours. This allows you to keep track of a time zone other than the local time, already marked by the hour hand (which completes a cycle in 12 hours).
Technical specifications
A new GMT caliber
The case
With its 39mm case, Nereide GMT is designed both for those who are seduced by one of the most beloved mechanical complications, and for those who are loooking for a diving watch with unusual color combinations and special mirror and glossy finishes, a distinctive feature of this new collection.
Bezel insert
The bezel insert is made of BK7 optical crystal and adopts a particular mirror finish in the lower half, a unique feature of the GMT collection. This material has exceptional physical properties. It is lead free, lighter and is endowed with a better quality than other glass crystals. Its properties of low dispersion (with Abbe numbers around 60) and low refraction (≈1.52), combined with high clarity, make it perfect for creating high-precision and durable glass objects.
The caseback
The finely engraved caseback celebrates the adoption (for the first time in 1884) of the 24 time zone system as a global reference time system based on Greenwich Mean Time. Around the representation of the terrestrial globe, the major cities of the world are shown next to their respective time zones. This way, you can set the time zone in the traditional way without needing your smartphone.
