Hello everyone, I am Bokey. In this issue of Old Watches, New Talks, I bring you the IWC Portuguese chronograph with white dial and blue hands from ZF factory. The official model is IW371602. I believe friends who like chronograph watches should be very familiar with the IWC Portuguese chronograph series (abbreviated as: IWC Portuguese chronograph). Moreover, in the Zhanxi market, the classic Portuguese chronograph with white face and blue hands from ZF factory is also very popular among watch enthusiasts. However, recently, a small number of ZF factory’s IWC Portuguese 150th anniversary commemorative watches have arrived on the market again. This 150th anniversary special edition Portuguese chronograph with model number IW371602 has attracted the interest of many watch enthusiasts. So, let’s take this white dial and blue hands model as an example to see how this new ZF 150th anniversary commemorative Portuguese chronograph is?

Authentic parameters: IWC 150th anniversary series IW371602 watch. Price: 59200.


This IWC 150th anniversary commemorative Portuguese chronograph still continues the three iconic designs of the Portuguese series: Arabic numerals, willow-leaf hands and curved lugs. The enamel white dial paired with blued steel hands is very good-looking! Moreover, the see-through back design element makes friends who like see-through backs more fond of it.

Overall, the ZF factory’s 150th anniversary commemorative Portuguese chronograph uses a sapphire crystal mirror coated with double-sided blue film, which is very transparent. When viewed from different angles, it is very beautiful under sunlight. Coupled with the blued steel hands, it is even more dazzling. Moreover, the dial uses a baking paint process, and the scales use a superimposed printing technology. The overall texture can compete with the authentic one.


For dial details, I won’t go into too much detail here. Let me show you a few detail pictures. A good product looks good no matter how you take pictures!

Unlike the previous old model Portuguese chronograph, the ZF factory’s IWC 150th anniversary Portuguese chronograph synchronizes with the see-through back design of the authentic one and uses the Dandong 7750 movement modified to the original CAL.69355 movement. In terms of thickness, various size data, movement layout, and balance wheel position, it reaches more than 95% similarity.



In terms of straps, the ZF factory’s anniversary Portuguese chronograph comes with a standard pair of calfskin straps. The texture is a bit harder. Friends who pursue wearing comfort can add money to upgrade to crocodile leather straps.

The overall restoration degree of the buckle is high, the engraving craftsmanship is exquisite, and the visual effect is basically the same.
