Overview

About this reference

The 15450ST is the 37mm steel selfwinding Royal Oak from the same generation as the 41mm 15400ST, produced from 2012 to 2022. It keeps Calibre 3120 and Grande Tapisserie, with applied white-gold hour markers and a see-through caseback, in a distinctly smaller case. Shoppers looking for a smaller Oak often land here when they do not actually want the 39mm Jumbo.

Size is the first filter, and several listings that ship to Saudi Arabia are sloppy about it. A 41mm bracelet watch in the photos is probably a 15400ST. The 15202ST is 39mm and extra-thin on Calibre 2121. The 26240ST is a later steel chronograph at 41mm.
