Produced by SJ .F1 Factory's true core masterpiece: the strongest steel king, Audemars Piguet 15400 integrated movement CAL3120 version. RW5 .1. Adopts a three-piece structure consistent with the original version. All positions and assembly methods of the case are identical to the authentic model.2. The steel bracelet, being the most critical part of the watch, is crafted using molds from the original bracelet, ensuring meticulous brushed patterns that are not sharp to the touch. The thickness and joints of the bracelet match the original perfectly, with an unwavering attention to detail.3. The connection at the bracelet head to the case features a movable cushioning design, consistent with the genuine product, allowing for a more comfortable fit against the wrist.4. The clasp's opening mechanism and feel, as well as the engraving craftsmanship, are all aligned with the original.5. F1 Factory restores the original dial's workmanship and color details so flawlessly that there are no discrepancies when placed alongside the genuine article.6. The movement is the soul of the watch and a key factor in distinguishing authenticity. F1 Factory perfectly replicates the original 3120 movement, creating a true integrated movement, no longer just a decorated movement. Specific details include: . 1. The date jumps instantaneously in the reverse direction, unlike the 9015 movements on the market which use a spacer, resulting in a different date orientation. 2. The center axis of the hands is solid and matches the original, with polished hands that are free of burrs. 3. No gears on the back of the movement are decorative; the small gear of the winding mechanism is functional, and both the flat balance spring and gears on the mainspring barrel are genuinely movable and usable. 4. The position of the balance wheel corresponds to the authentic product at the 7 o'clock position, with a power reserve time identical to the original at 41 hours. The movement's shock absorbers and other details are restored to match the original. 5. The color of the movement's rotor is often misrepresented; the official website shows a rose-red hue, while the actual rotor leans towards gold. This has led many on the market to produce rotors in rose-red, but F1 Factory has specially adjusted the rotor color to match the original, while others remain predominantly red.F1 Factory's true core sincerity, perfectly restored! S1 exquisitely recommends this men's mechanical watch.
