One of the most notable complication featured in the Portuguese case is the perpetual calendar. First introduced in 2003, it features a 44mm diameter case encasing a symmetrical dial layout with moon phases, 7-day power reserve indication and most notably a digital year display.

The present example ref. IW503203 is the second Portugieser perpetual calendar reference launched in 2010. Encased in an elegant 44mm diameter white gold case, the blue dial is perfectly matched with silvered accents and applied Arabic numerals. Offered in excellent overall condition, the present lot is accompanied by its full set of accessories and consigned by the original owner.
