Local time is displayed on two bezels: one for the hours on a grey satin bezel and one for the minutes on a thin black bezel. Each time indication has its own hand with a red triangular tip filled with luminous material. These hands move on two other rings and are engraved with the studio’s cherished key words to show GMT.
Finally, an off-centre display at 10 o’clock indicates the second time zone with blue-gold hands. For the caseback of the timepiece, Greubel Forsey has kept the disc with 24 time zones, indicating the UTC time of the 24 reference cities, with one change: UTC in Paris has been set by Greubel Forsey since its inception replaced by cities. Foundation: La Chaux-de-Fonds, Switzerland.
The 30° inclined balance at 7 o’clock is held by a beautiful flat black polished and barrel polished steel balance bridge on a polished steel column. On its right, the small seconds hand displayed by a blue-gold hand completes the whole.
