Universal time watches allow wearers to set the hands automatically to the time of one of 24 cities visible in a window or rotating disc. Unlike world time watches, which look the same but only display the hour in 24 time zones at a glance and require a great deal of adjustment to adapt the time displayed by the hands to the country of choice. To change the time on this Breguet Hora Mundi watch and adjust it to the desired time zone without losing the local time or the day/night indication, you simply turn the crown at 8 o’clock on the white gold middle case. An exceptional timepiece to wear on a blue rubber strap, it features a highly structured dial with a world map in relief on a wave-shaped guilloché background. As always with Breguet, it is powered by a self-winding manufacture caliber visible through a sapphire caseback.
