The Replica IWC Portugieser IW500701 1:1 Top Quality ZF Factory V3 White Dial uses a rose gold case and the embedded hour markers on the silver-plated dial are also made of rose gold. The left and right symmetrical small dials are the power reserve indicator at three o’clock and the small seconds at nine o’clock. It can be recognized from the appearance that this is the most classic design of the Portuguese series. The watch uses the self-produced 52010 movement. This movement has two most commendable features: First, it is an automatic winding device. The winding principle of a traditional automatic mechanical watch is based on the swing of the wearer’s arm. The metal balance wheel in the automatic mechanical system continuously rotates to drive the levers and gears in the system to wind the mainspring. All automatic mechanical watches on the market are similar in the same way, showing different forms under the same concept, except for Jaeger-LeCoultre’s air The clock uses temperature changes to change the shape of the inner metal bar to power the gears to wind the mainspring.
IWC has always been a world-class watch brand. It has many commendable aspects in terms of expertise, including what we often call “Woodpecker” Billerton winding system, Billerton automatic The chain system was developed by Billerton, the technical director of IWC, and was patented in 1946. This system was further improved in 1950. The basic principle is that there is an eccentric cam behind the automatic oscillating weight of the movement. The cam rotates between the two pulleys of the “Woodpecker” to drive the entire system. The principle of the tribute rod makes the “long bird nozzle” and “short bird nozzle” in the system continuous The ground moves relatively up and down, forming a “long bird’s mouth” pulls down and a “short bird’s mouth” slides up; the “short bird’s mouth” pulls down and the “long bird’s mouth” slides up, constantly pulling the oblique tooth wheel to wind the mainspring At the same time, the “Woodpecker” winding structure also has a shock absorber arm, which can slow down the shock and vibration during wearing. The movement of IW500107 that everyone sees today uses the Bieleton winding system. Second, the 52010 movement created a double barrel to ensure a 7-day power reserve. Although this resulted in the case being too large and thick, it was very rare in the early long-powered watches. This also represents the pinnacle skill of the watch industry’s long power system at that time.
All in all, the design of the Replica IWC Portugieser IW500701 watch inherits the charm of the legendary Portuguese watch born in the 1930s, and combines the top movement skills of today’s IWC.
