With a 44mm diameter, the Royal Oak Tourbillon Chronograph stands as one of the most substantial non-Offshore models in the collection. It utilizes the manual-winding caliber 2889, a movement that merges a tourbillon with a column-wheel chronograph. Reference 25977BA.OO.D088CR.01 features a yellow gold case, a silver dial, and an integrated alligator strap.
