The OCTA Royal Oak Chronograph 26240 features a 41mm stainless steel case measuring approximately 12.4mm thick, with the signature octagonal bezel, eight exposed hexagonal screws, and integrated bracelet architecture.
The centerpiece is the green Grande Tapisserie-style dial, featuring a deeply textured geometric pattern that creates depth and shifts between rich green and darker khaki tones depending on the surrounding light.
Three matching green chronograph registers maintain a cohesive appearance, while applied luminous baton hour markers and Royal Oak-style hands provide strong contrast and legibility.
A discreet date display is positioned between 4 and 5 o’clock, preserving the distinctive layout of the 26240 chronograph.
The stainless steel octagonal bezel combines satin-brushed surfaces with polished bevels. This contrasting finishing continues across the case and integrated bracelet, emphasizing the sharp geometry of the Royal Oak design.
A sapphire crystal with anti-reflective coating protects the dial, while the sapphire exhibition caseback displays the decorated automatic chronograph movement.
The integrated stainless steel bracelet flows directly from the case, combining brushed primary surfaces with polished edges and a folding clasp.
Powering the watch is the Shanghai JingHe JH4401 Automatic Super Clone, featuring a true free-sprung balance architecture with a regulator-free design.
The movement incorporates a fully functional flyback chronograph, allowing the chronograph to be reset and restarted without first stopping it. It operates at 28,800 vph and provides hours, minutes, running seconds, date, and chronograph functionality.
With its green Grande Tapisserie-style dial, 41mm stainless steel construction, integrated bracelet, and upgraded JH4401 free-sprung flyback movement, the OCTA 26240 delivers a distinctive combination of mechanical complexity and Royal Oak styling.
