Audemars Piguet Royal Oak Jumbo A-Series Ref:5402ST – Icon of Haute Horlogerie

Housing and design

The Audemars Piguet Royal Oak Jumbo A-Series is considered a milestone in the history of luxury watches. Its iconic case measures 39 mm in diameter and is made of stainless steel – an expression of sporty elegance and technical sophistication. Characteristic is the octagonal bezel design with visible screws, which is reminiscent of the shape of old diving helmets and has defined the DNA of the Royal Oak since 1972. The “Petite Tapisserie” dial in blue with fine guilloché decoration provides depth, play of light and a high recognition value. Applied indices and the flat-ground hands are provided with luminous material and ensure excellent readability – discreet and striking at the same time. An anti-reflective sapphire crystal rounds off the overall picture and optimally protects the finely crafted dial.

Movement and technology

Inside the Royal Oak Jumbo A-Series is the ultra-thin calibre 2121 – a high-precision automatic movement. It has a power reserve of approximately 40 hours at a frequency of 19,800 vibrations per hour. With a height of only 3.05 mm, it is one of the thinnest automatic movements with a central rotor and is known for its durability and precision. The workmanship of the movement is decorated by hand and protected by the closed case back of the A-Series – in the spirit of historical authenticity.

Bracelet and wearing comfort

Designed by legendary designer Gérald Genta, the integrated stainless steel bracelet with a satin-finished and polished finish is a masterpiece of ergonomics. It nestles flat on the wrist and offers a smooth transition from the case to the strap thanks to its link structure – a true trademark of the Royal Oak. The double folding clasp ensures a secure hold and stylishly rounds off the wearing comfort.

Functionality

The Royal Oak Jumbo A-Series deliberately limits itself to the essentials: central hour, minute and second display as well as a date window at 3 o’clock. She dispenses with superfluous complications in favor of clarity, understatement and pure aesthetics. With a water resistance of up to 50 meters (5 bar), it remains a reliable companion in everyday life. The combination of iconic design, watchmaking masterpiece and rarity value makes this model one of the most sought-after collector’s watches worldwide.
