ZF re-enacts the IW371440 IWC V2 version of Portugal's super slim Portuguese meter

ZF IWC V2 version Portuguese super ultra-thin Portuguese meter IW371440. 40.9mm diameter. 12.3mm thick. Black belt/brown belt. It took up to 18 months to overcome many difficulties to develop and replicate the genuine A79350 movement. The improvement achieved by using the improved movement is

1. The thickness of the case is 13.5mm before the authenticity (only 12.3mm) because of the limitation of the thickness of the 7750 movement.

Second, the head and the upper and lower timing buttons are parabolic (previously a vertical line) after the improvement, the whole is more harmonious and perfect. 100% restore the authentic and elegant style.

Third, the assembly sequence and structure of the three-piece ring, middle shell, and bottom cover are the same as the original product (all are fixed by screws)
