IWC Portuguese Chronograph Classic... Movement: Dandong 7750 movement modified

IWC Portuguese Chronograph Classic... Movement: Dandong 7750 movement modified to match the original Cal.69355 movement. Thickness, unit dimensions and layout, balance wheel position, and functions are all perfectly aligned and flawless. Case and watch dimensions: 13.1mm transparent case back, 12.3mm solid case back, identical to the original. Same size, perfect texture, ergonomic design makes the streamlined lugs fit the wrist more comfortably. Consistent with the original: dial uses a baked enamel finish, and the markers use a superimposed printing technique. Overall texture is comparable. Complete with over ten facets, Italian leather strap, and classic IWC folding clasp. Zero returns, transparent case back, and solid case back available now...
