Coming in an array of materials and dial colours, the latest “Jumbo” collection pays tribute to the timeless icon from 1972. The four models are powered by the new selfwinding movement, Calibre 7121, fitted with the dedicated “50-years” oscillating weight matched to the case colour.
The stainless steel “Jumbo” version has retained the aesthetics of the original Royal Oak 5402. The steel case and bracelet, hand finished with satin-brushing and polished chamfers, are complemented with the watch’s iconic "Petite Tapisserie" dial and "Bleu Nuit, Nuage 50" hue.
Although originally achieved through galvanic bath, the dial’s blue colour is obtained today through PVD (Physical Vapor Deposition) to ensure a more homogeneous colour across the collection. The "Petite Tapisserie" consists of hundreds of small truncated pyramids carved out on the dial’s thin metal plate by an old guilloché copying machine. Tens of thousands of diamond shapes are simultaneously cut out in the thin grooves separating the square bases.
Contrary to the original model, the sapphire caseback grants view of Calibre 7121 and the anniversary oscillating weight here in rhodium-toned 22-carat pink gold. Calibre 7121 has been finished with refined Haute Horlogerie decorations visible through the sapphire caseback.
The new “Jumbo” collection includes a pink gold and a yellow gold model, both enhanced with the trademark "Petite Tapisserie" dial in new smoked shades. The 18-carat pink gold model is contrasted with smoked grey hues, while the 18-carat yellow gold version is illuminated with smoked yellow-gold tones.
Reserved for the AP Houses, this elegant timepiece contrasts its hand-finished 950 platinum case and bracelet with a smoked green dial, whose base is decorated with a sunburst pattern. It represents today one of the rare 39 mm models honed from this precious material that has made its way into the Royal Oak core collection.
The vivid green shade is obtained by adding drops of green colouring to the dial’s protective varnish. The smoked effect on the dial’s periphery accentuates the colour’s intensity, while giving it more depth.
The new selfwinding Calibre 7121, which measures 3.2 mm in thickness, has been specifically conceived to fit in the extra-thin 8.1 mm “Jumbo” case without altering its aesthetic and thickness. It is also equipped with a patented extra-thin date-setting system.
Calibre 7121 replaces extra-thin Calibre 2121 (3.05 mm) first introduced on the Royal Oak in 1972, which retired at the end of 2021. Calibre 7121's large barrel confers it more power than its predecessor, making it more precise for a longer period of time.
