On the ww.tc Lady’s dial, a disk indicating the 24 hours is synchronized with the hour hand. The second mobile disk, which indicates the names of 24 cities (one for each time zone), simply has to be adjusted accordingly. The bezel is covered with 54 diamonds, while 8 mark hours on the dial. At 41mm, it has an imposing diameter, and the case has been carefully designed so that the lugs wrap themselves snugly around the wrist. Girard-Perregaux has provided this timekeeper with an automatic winding movement, which, along with the hours-of-the-world function, displays a power-reserve indicator and a small seconds hand. The movement can be admired through the transparent case back.
