Crafted from sandblasted titanium, the 44mm case measures 16.15mm in thickness and is fitted with glareproofed sapphire crystal on both the front and caseback. Black ceramic pushpieces and a screw-locked crown are protected by sandblasted titanium pushpiece guards, while the entire construction carries a water resistance rating of 100 metres.
The dial opens up to reveal the selfwinding movement within, framed by a black inner bezel with blue transfers. A black 30-minute counter with white indications tracks elapsed time, and openworked white gold hands complete the layout. The visual depth created by the open construction gives the wearer a direct view into the mechanical complexity beneath.
A blue rubber strap with a titanium AP folding clasp secures the piece to the wrist, and an additional black rubber strap is included, allowing the wearer to tailor the look of the watch to suit different occasions. Reference 26587TI.OO.D031CA.01 represents one of the more technically ambitious expressions within the Royal Oak Concept family.
