The connection between the bracelet and the case features a movable cushioning design, identical to the genuine product, enhancing comfort and fit around the wrist.4. The clasp's opening mechanism and texture, as well as the engraving craftsmanship, are consistent with the original piece.5. F1 Factory has perfectly replicated the original dial's craftsmanship and color details, making it indistinguishable from the authentic version.6. The movement is the soul of the watch and a key point for identifying authenticity. F1 Factory has flawlessly reproduced the original 3120 movement, creating a true integrated movement rather than a decorated one. Specific details include:. 1. The calendar features a reverse instantaneous jump, differing from the commonly found 9015 movements with added plates, as the calendar direction is not the same. 2. The central axis of the hands is solid and matches the original, with polished hands free of burrs. 3. No gears on the movement's back are for decoration; the winding gear's small cog transmits power, and the gears on the flat hairspring deck and mainspring box are all functional and in motion. 4. The balance wheel is positioned at 7 o'clock, with a power reserve t.mes
of 41 hours, consistent with the authentic model. The movement's shock absorber and other details are restored to match the original movement. 5. The most common error is the color of the movement's rotor; while official images show a rose-red hue, the actual rotor is different. Many market replicas use the rose-red color, but F1 Factory has specially adjusted the rotor color to match the original, which is generally less red.F1 Factory's true movement is sincere and perfectly restored!
