The dial features a silver-gray guilloche background, with a central enamel-fired blue Earth pattern and a 24-hour scale ring. It can display the time of a second time zone and also switch between winter time and summer time. The city name window is displayed on the left side. Roman numeral hour markers are paired with blue steel hands and rose gold folding clasp. Equipped with the transparent caseback Cartier self-produced 9914 MC automatic movement, it is specially designed for multi-time zone function. Limited to 230 pieces worldwide, and since the Turtle-shaped series itself is a classic model of Cartier, its circulation and retention value are both very stable. Complete set
