If you feel Rolex and Omega are too high-profile, you might as well choose this IWC Portofino. Its design is minimalist yet lacks no noble temperament. With the MK Factory perfect version craftsmanship, every detail is handled appropriately, and the exterior is consistent with the genuine item. Even as a genuine piece, it is a favourite among many, and while a price of over twenty thousand is relatively attractive, buying this one-to-one model feels much more practical.
The 9015 movement version from the MK Factory is slightly thicker than the genuine piece, but there is no major visual difference, and it can only be felt during actual wear.
Overall, the Portofino by the MK version performs quite well; there are differences but no obvious flaws. The overall replication level should be better than the Portuguese Chronograph, making it a very worthwhile watch to acquire.
