Steel case, steel bracelet, deep blue dial — the replica royal oak offshore 26238ST blue is the current-generation 44mm Offshore chronograph in its most complete form. The 26238 replaces the 26400 series with the Cal. 4404 flyback chronograph, gaining 20 hours of extra power reserve and a higher beat rate. The steel bracelet is a significant departure from the rubber straps that defined the Offshore for decades, giving this reference a presence and weight that the rubber-strap versions cannot match.
The 26238 Generation
When AP introduced the 26238, it signaled a clear direction for the Offshore chronograph. Cal. 4404 replaced the 3126/3840 with a flyback function, meaning you can reset and restart the chronograph in a single pusher press without the stop-reset-start sequence. Power reserve jumped from 50 to 70 hours, and the beat rate increased from 21,600 to 28,800 vph for smoother timekeeping and a more fluid seconds hand sweep.
The steel bracelet option is perhaps more significant than the movement upgrade. For years, the Offshore chronograph came exclusively on rubber straps. The integrated steel bracelet changes the weight balance, the wrist feel, and the visual impression. It picks up the alternating brushed and polished finishing that defines AP’s metalwork, turning every link into a demonstration of their surface treatment capability.
Deep Blue on Steel
The deep blue dial on Mega Tapisserie creates a surface that shifts between dark navy and vivid blue depending on the viewing angle. Under artificial light it tends toward darkness; in sunlight the raised portions of the tapisserie pattern catch and scatter blue wavelengths. The sky blue 26238ST offers a lighter, more playful take on the same platform.
On the steel bracelet, this replica royal oak offshore 26238ST blue is the heaviest Offshore in the steel lineup. The weight is not excessive — it distributes well across the wrist — but it is noticeable compared to the rubber-strap versions. The folding clasp includes micro-adjustment for fine-tuning the fit.
