Collector Insighĺ
The 16013 stands out for its two-tone yellow gold/steel construction, a hallmark of the Datejust’s aesthetic appeal and enduring popularity among vintage collectors. 
As a vintage reference featuring the calibre 3035 movement with quick-set date, it represents a significant technical phase in Rolex’s development. 
Market data suggests moderate long-term appreciation; for example, its five-year growth is modest (~+0.3%) and shorter-term performance has seen slight declines.
