The 5110P is particularly recognizable for its compact 37mm Calatrava-style case and distinctive two-disc World Time display. A pusher at 10 o’clock allows the wearer to advance the local time zone while the city and 24-hour discs move together.
One small terminology point: dealers may describe this as “silver dial,” “silvered dial,” or “silver and blue dial.” The platinum 5110P examples documented by major auction houses commonly have a guilloché blue centre with silvered World Time discs
