Hello everyone, I am purewatches, a watch enthusiast. Today I will bring you an in-depth analysis of the ZF factory IWC Portuguese Chronograph series (referred to as “Portuguese Chronograph”) replica watches, focusing on the choice of dense bottom and transparent bottom versions. For those who like IWC Portuguese designs, should I choose a dense bottom or a transparent bottom? What are the differences between these two versions in terms of appearance, movement, cost performance, etc.? Is it worth buying? Let’s find out!

Background analysis of genuine and replica watches
In recent years, genuine IWC has launched a new model equipped with the 69355 model movement, completely getting rid of the early movement structure based on the 7750. The new model not only has a two-way winding function and a power reserve of 46 hours, but also adopts a back-transparent design to show more ornamental movement parts. It can be said that the launch of the new Portuguese watch has given this classic watch a new lease of life.

However, the situation in the replica watch market is quite different. Due to technical limitations, most replica watches still use the domestic 7750 movement as the basis. In order to imitate the back-through effect of genuine products, some manufacturers will add “fake decks”, but these decorative parts are not only inoperable, but can also easily cause malfunctions. Therefore, when choosing a replica watch, the advantages and disadvantages of dense bottom and transparent bottom need to be carefully weighed.

The dense version: the first choice for practicality and stability
The dense bottom version is currently the mainstream choice in the replica watch market, especially suitable for players with limited budget or those who focus on practicality. Here are the main advantages of the dense bottom version:
- Movement stability is higher
The dense bottom version is equipped with an optimized customized 7750 movement. After years of correction, the failure rate has been significantly reduced. The metal bottom cover covers the movement, which not only avoids the embarrassment of “fake at first glance”, but also improves the overall texture. - more affordable price
Compared with the transparent bottom version, the price of the dense bottom version is usually slightly lower and more cost-effective. This is a good choice for those with a limited budget. - High degree of appearance restoration
From the front, the dense-soled version is almost the same as the original, especially the old color matching. There are already more than ten choices, which can fully meet the daily matching needs.

Transparent version: beautiful but with hidden dangers
Although the transparent version looks more attractive, there are many problems in the field of replica watches:
- “False deck” problem is serious
In order to imitate the back-through effect of the genuine 69355 movement, many manufacturers will add a “fake deck” to the 7750 movement. However, not only do these decorative parts fail to function, they can easily fall off, causing the movement to jam or malfunction. - Thickness increased significantly
The thickness of the transparent bottom version is usually about 2mm more than the dense bottom version, which can be clearly felt with your hands. This difference not only affects the wearing comfort, but also appears to be insufficiently refined. - Low cost performance
The price of the transparent bottom version is usually higher than that of the dense bottom version, but due to frequent movement problems, the actual experience is not ideal. Rather than spending more money on a “metal toy”, opt for a more stable dense-soled version.


Summary: How to choose a version that is more suitable for you?
If you are pursuing a genuine watch and have sufficient budget, you should undoubtedly choose the new see-through version, because the 69355 movement it is equipped with has superior performance and the see-through design is more ornamental. However, for replica watch players, the dense bottom version is undoubtedly a wiser choice. Not only is it affordable and has a stable movement, it can also effectively avoid the embarrassment of “fake at first glance”.



In short, when choosing a replica watch, don’t blindly pursue “fake and real” in appearance, but consider practicality, cost-effectiveness and stability. I hope this article can help everyone better understand the difference between the dense bottom and the transparent bottom of the ZF factory IWC Portuguese watch, and help you avoid detours on the road to playing with watches!
