THE PRINCELY TOUCH As with all “Le Petit Prince” editions, the dial features the signature deep blue with a sunray-brushed finishing. The vertical layout of the counters is clean and symmetric with a recessed and snailed 60-minute totaliser for the chronograph at 12 and small seconds at 6 o’clock. The large stylised Arabic numerals are applied to the dial and filled with luminescence, as are the propeller-style hands and the triangle and two dots at noon. Substituting the numeral 3 is a date window with a white background.
