The 5990R elevates functionality through its 18k rose gold construction while retaining the full travel time and chronograph architecture. The dial presents dual time functionality with separate hour hands, day and night indicators, and a date linked to local time, alongside a flyback chronograph display. The automatic movement powers these complications with precision, housed within a robust yet refined case. The bracelet, also in rose gold, integrates seamlessly into the case design, delivering both structural continuity and visual impact.

This reference carries a stronger identity than its steel counterpart. It combines mechanical complexity with material weight, offering a commanding presence suited for collectors who prefer both technical depth and unmistakable luxury.
