Audemars Piguet Millenary 4101 Watch

The watchmaker of Le Brassus in Switzerland has completed a great initiative, allowing you to wear the movement directly on your wrist! They realize their dreams for those who love high-end watchmaking technology, and let the exquisite mechanical devices ‘face out’ and show them to the world. Instead of exposing the movement only through the transparent sapphire crystal case back, it is a twisting design that allows the movement to be seen on the surface of the Millenary Millennium 4101 watch! The new and unique horizontal elliptical movement is closely combined with the Millenary Millennium elegant and luxurious horizontal elliptical case, intertwined with the visual senses and enjoy the wonderful performances of the top watchmaking craftsmanship, which will delight the watch connoisseurs and outstanding tasters .
Demystifying the core of the watch
   The new design broke the boundaries between inside and outside, overturning the norm that watch design only involves external components such as dial, case and strap. Ordinary watches often only focus on the appearance design, but for the internal movement only care about functionality but ignore aesthetic requirements. The Millenary Millennium 4101 watch is beautiful both inside and out. Functionality and aesthetic design blend together, regardless of each other. From the research and development of the watch to the production, in close cooperation with all the teams of Audemars Piguet, two new models such as a stainless steel case with a black alligator leather strap and a rose gold case with a brown alligator leather strap Watches combine form and content with superb craftsmanship.
    The Cal.4101 movement, which is completely designed, developed and manufactured by Audemars Piguet Watch Factory, adopts the structure of ‘turning the sky’, exposing the mechanical device that has always been hidden deep in the case on the surface. To achieve this, the adjustment components such as the balance wheel, the pallet fork and the escapement system have been redesigned to attract everyone’s attention at the 9 o’clock position on the surface: the adjustable weight balance with eight small weights is brilliant The style, the horizontal balance wheel bridge shows its unique heroic posture. Connoisseurs who have noticed even the slightest can even see the delicate tiny escapement fork and escape wheel.
    Twelve bridges form a beautiful picture on the surface of the movement. Audemars Piguet has turned these practical bridges used to fix different components into decorative design elements: these bridges have three beautiful parallel arcs on the surface, horizontal Geneva ripples, pearls on the bridges The delicate decoration such as polka-dot grinding and snail-shaped threads contrasts with the multi-layered movement structure, while also enhancing the contrast effect and the sense of depth. The exposed screws distributed on the left side of the surface echo the arc of the horizontal oval case, which adds to the richness of the entire picture and also has a more sense of technology. At the top of the dial at 10, 11, 12 o’clock, there are several dazzling semi-spherical rubies above the finishing touch, making the entire surface more layered.

    All the technical components that are indispensable for the structure and function of the movement play a pivotal role in the overall aesthetic design of this watch, and they work with the Millenary Millennium Series horizontal oval case, eccentric dial, Classic features such as Roman numeral hour markers, matte finish on the middle of the case and bright finish on the bezel are combined to create a natural watch, which stands out with its 3D three-dimensional design dial and high-tech appearance. Following the epoch-making masterpieces such as the fifth of the Tradition of Excellence, the millennial jumping seconds watch, and the millennial MC12 watch, the Millenary millennial 4101 watch is on the journey of bold exploration A new milestone.
Accurate travel time, reliable performance, beautiful decoration
    The Cal.4101 oval movement reverses the ingenious design of the universe, giving the new millennial watch a unique aesthetic. In addition, the reliability of the movement is also worth paying attention to. The core components of the movement adopt an adjustable weight balance that vibrates 28,800 times per hour. Eight small platinum weights keep the movement’s adjustment stable for a long time, and are equipped with Breguet hairsprings. The adjustable weight balance’s higher swing frequency and inertia make the movement more accurate, and it is also less susceptible to external forces. The horizontal-to-horizontal balance wheel bridge plate is fixed on both sides of the machine plate instead of one side, so the shockproof effect is better.
    An automatic disk made of 22K gold is assembled on a ceramic ball bearing to ensure that the two-way self-winding reverser also uses ceramic ball bearings. The two-way automatic winding device has the advantages of anti-wear and can be paralleled with other functions. It can speed up the winding speed, enable the barrel to regularly output stable power, and greatly improve the accuracy of travel time.

Stainless steel case Millenary Millennium 4101 watch.
    The Cal.4101 movement components are hand-assembled and decorated in the Brass-Audemars Piguet watch factory, ensuring excellent quality throughout the production and precision decoration process. The stainless steel case style is equipped with a dark gray electroplated movement, which is low-key and elegant; the rose gold case version is equipped with a rhodium-plated and gold-plated movement. The bridges are carefully chamfered and polished to give a sharp and shiny edge. The edges of the ruby ​​assembly holes are polished with diamonds, and the wheel arms of the gears are chamfered. Each screw head and the periphery of the screw hole are decorated with diamond polished mirrors. Both sides of the board are decorated: Geneva waves are decorated on the front, and two different sizes of pearl dots are polished on the back to enhance the contrast and three-dimensional depth. The upper bridge near the surface is decorated with horizontal Geneva ripples and snail-shaped threads and is polished with pearl dots. The lower bridge near the case back is decorated with circular Geneva ripples and snail-shaped threads, and is polished with pearl dots. The 22K gold automatic plate is engraved with AP and Audemars and Piguet family crests.
