Nautilus launched a true all-in-one machine, improving the position and direction of the balance wheel swing arm. Detailed upgrade interpretation: 1. The upgraded movement is all finely engraved, clear and not worn, and the texture is the ultimate. 2. Upgrade the automatic rotor, adopt Swiss ultra-precision bearings, and install the rotor with unprecedented technology in the industry. 3. Original movement, no fake plate, no fake balance wheel, no fake ruby. Complete re-engraving of the 3.3mm out-of-print high-quality 9019 modified 324SC integrated movement. 4.. Upgraded dial scale with super bright night light, and the overall harmony and synchronization of brightness. 5. Nautilus classic blue plate, currently improved to match the original color. 6. Each watch in the calendar window is horizontally aligned, and there is no oblique occlusion. 7. Multiple adjustments to adjust the smoothness of the head adjustment gear, and adjust to the best state. Makes the upgraded version adjust the time and feel smooth. 8. The thickness of the entire watch is upgraded to 8.6 mm, which perfectly realizes the thinnest mechanical watch on the whole network, which is equivalent to the original thickness. It is extremely comfortable to wear. 9. Emphasize that the 324Sc integrated movement adjusts the calendar clockwise, that is, adjusts the calendar from top to bottom. Note that the analysis is consistent with the genuine product. 10. When adjusting the time, pull the crown to the second gear. The big second hand does not stop. It is also consistent with the original. The original machine produced the Patek Philippe 5711 Nautilus, the real 324SC all-in-one machine, the hottest model that will dominate the entire network in 2022!
