Overview

About this reference

The 15202ST is the steel Jumbo Extra-Thin, and in the Royal Oak family that still means something the 41mm watches cannot. Thirty-nine millimetres, extra-thin, Calibre 2121, from 2000 to 2021: a time-only octagon that stayed in production long after the larger selfwinding watches arrived. It sits beside those later 41mm pieces, not beneath them.

Jumbo listings get padded with 41mm steel Oaks, even when fewer Saudi-shipping offers exist for this exact reference. Confirm 39mm, extra-thin construction, and Calibre 2121. The 15400ST is 41mm and a different generation. The 15450ST is 37mm. The 15202OR is the same Jumbo in pink gold.
