The Royal Oak Chronograph reference 26320ST.OO.1220ST.01 arrives in a 41mm stainless steel case defined by its fixed bezel set with eight hexagonal screws and a solid case back. Scratch-resistant sapphire crystal protects the dial, while 50 metres of water resistance rounds out a package that balances sporting intent with refined execution. A butterfly double-fold clasp secures the stainless steel bracelet.
The black dial is arranged with hours, minutes, and a running seconds display alongside three chronograph subdials positioned at 3, 6, and 9 o'clock. A date aperture sits between 4 and 5 o'clock, completing a layout that remains immediately legible. The case measures 41mm and wears with the characteristic slim profile the Royal Oak line is known for.
Inside, Caliber 2385 — a self-winding chronograph movement — drives the full suite of functions with an approximately 40-hour power reserve. This pre-owned example offers the opportunity to acquire one of the Royal Oak Chronograph's most recognised references in stainless steel with a black dial.
