Featuring slender Roman numerals and a moon phase indicator, the Portofino Hand-Wound retains the classic grace of the 24-year-old original. The 98800-calibre hunter movement restores the moon phase and seconds to their traditional 12 and 6 o'clock positions, while the moon phase accuracy is enhanced to a deviation of only one day every 122 years. Housed in the same 46-millimetre case, the movement includes a Jones-based design with a nickel-plated three-quarter plate, screw balance, Breguet spring, and elongated index, with adjustments made via the crown.
