An elegant design, a sophisticated and stylish appearance. The dial diameter of MKS IWC Portofino is 40 mm and its thickness is 9.5 mm. Sapphire crystal is used as glass and has been treated with anti-reflection. MKS Factory has done a really good job in the front end comparison!




Dial and Hand Details
The length of the hour and minute hands and the fineness of the inscriptions on the dial surface are exactly the same. Each hour marker on the dial is produced with a separate mold, processed one by one, then PVD platinum process (rhodium plating) is applied; Its color is bright and its shine is full. Additionally, the size of the date window and the date font are very close to the original, including the hour and minute hands with Roman numeral stripes between the hour markers.



Case and Body Workmanship
Case thickness 9.5 mm; Made of stainless steel machined on high-end CNC machines. The entire body of the case is the same as the original. There are minor shortcomings in the details!





A closed case back design is used on the back. The lettering and serial number engraving on the outer frame are very well done; clear, complete, very soft and natural. The size is exactly the same as the original. In the movement, MKS Factory used the extremely stable 9015 caliber; Failure/service rate is very low. The only downside is that the rotor noise is a bit loud.



Strap, Buckle and Comfort
On the strap side, the MKS factory standard version comes with a calfskin strap; The texture is soft and the grip is not bad. The original is crocodile skin; Perfectionists can also purchase an alligator leather strap. The logo engraving on the buckle is perfect and the workmanship is fine. The pin buckle is carefully crafted; There is not the slightest stinging or rough feeling!
