IWC - Long Dynamic Expert

The first impression that the 8th chain of IWC Portofino replica gave me was big. In order to accommodate the huge movement, the watch has a size of 45 mm and a thickness of 11.7 mm. Although it is 1 mm smaller than the big fly (flying 46 mm), from the perspective of a formal watch, the Portofino 8-day chain is super big. In addition, the country is used to making the bezel very narrow, and it looks very large, which further increases the size of the watch visually. At the same time, the case of Bo Tao Fino 8 calendar is very round, the case is polished, and it is in my hand that I have a smooth feel like a Cartier blue balloon. Although the size is not small, but it feels good after getting started, not as strong as a big fly.

The disk of the Portofino 8th chain is very classical. Use Portofino's iconic willow pointer and strip stereo time scale. The gold needle gold hour mark, at the same time we can see that the 6 o'clock small seconds outer edge, there is also a gold circle, and the pointer hour mark echoes. Unlike Dafei and Portuguese 7 at 3 o'clock, the Portofino 8th chain uses a curved power display at 9 o'clock on the dial, showing 0 to 8 days of power, of which 0 to 2 are red. , the prompt is going to be winding. At the 3 o'clock position, there is PORTOFINO (English) and the calendar window, and the curved power display is symmetrical. We can notice that the calendar window of this watch is located at the edge of the dial, which shows that there is a huge movement inside the 8th chain of Portofino.

Portofino 's 8-day chain uses the U.S. self-produced 59210 manual movement (59000 series), power reserve 192 hours (8 days), swing frequency 28800 times / hour, 30 jewel bearings. In fact, the movement of this movement has 9 days, but in order to prevent the loss of the clockwork torque caused by insufficient power, the travel time is not stable, so only 8 days of power is retained. A major feature of the 59000 series movement is the large, huge movement that fills the 45 mm case, and the huge movement looks very enjoyable. Thanks to the manual movement, all the splints of the movement can be seen. The splint on the back of the movement is divided into four sections, a larger spring splint, a walker splint, a smaller escapement splint and a balance splint. From there we can see the oversized barrel.
