In the replica watch market, there are at least hundreds of manufacturers. But only a few have both good reputation and steady sales, and ZF Factory is one of the top picks. Together with VS Factory, Victory Factory and Noob Factory, it’s known as the four major factories in the high-end watch copy industry, staying firmly in the top rank of 1:1 Best Edition Swiss Replica Watches for years.

Background of ZF Factory
ZF Factory is also called Z Factory. It was founded one year later than N Factory. The boss used to be a reseller for KW Factory. He bought over all goods from KW Factory for resale later on. After falling out in cooperation, he decided to start his own watch-making business, opened moulds by himself and competed directly with similar models from KW Factory.
ZF Factory first made its name with Panerai watches. It was upgraded and redesigned based on KW Factory’s works, improved details, craftsmanship and materials. Its classic models include Panerai PAM127, 604, 359, 312, 441, 382, 587 and other popular styles, gaining wide recognition in the market step by step. Now ZF Factory’s product line covers many luxury brands like IWC, Jaeger-LeCoultre, Audemars Piguet, Rolex, Panerai, Tudor and Hublot.
ZF Factory IWC Portuguese 7-Day Automatic V5 Ultimate Version Review
IWC Portuguese 7-Day is totally ZF Factory’s signature piece. Just like N Factory’s Green Water Ghost and V6 Factory’s Cartier Ballon Bleu, it’s regarded as a classic masterpiece in the replica watch circle. Right now it’s upgraded to the V5 ultimate version in the market.
The case of Portuguese 7-Day V5 uses 316L stainless steel. The dome-shaped sapphire crystal comes with double-sided anti-glare blue coating, bringing high transparency. The dial layout of this watch is quite special. The two small dials on left and right are second counters, which many people mistake for minute counters. The right side is the power reserve display for the 7-day movement. ZF Factory did a great job on restoring these two small dials. The power reserve indicator changes according to actual power storage, not just a fake decorative function. The 12 three-dimensional numeral scales adopt bluing heat treatment craft. The date window is inward concave in trapezoid shape with strong stereoscopic sense.

Comparison With Original Watch
The thickness of ZF Portuguese 7-Day is 0.5mm to 0.8mm different from the original one, and the weight gap is around 10 grams. Considering the price difference, most people can accept this small gap. It feels almost the same when wearing on wrist. The obvious gap lies in power reserve performance. Many watch lovers said the actual power reserve of V5 version only lasts 3 to 4 days. It’s enough for daily wear, but you need to wind it again if you don’t wear it over weekends. Whether you can accept this flaw is up to you, but I personally think it’s not a big problem at all.
Real Wearing Experience of ZF Factory Audemars Piguet Royal Oak
15500 Series
This is the best-selling line of ZF Factory. Other 15400 versions on the market are at least 11mm thick. ZF Factory modified Cal.3120 integrated movement based on 9015 movement, controlling the whole watch thickness at 9.8mm, with the same hand feel as the original piece.

Craft and Details
ZF Factory bought three original 15500 watches in white, blue and black to open moulds by disassembling the genuine pieces. The words “Audemars Piguet” on the dial are raised instead of flat against the dial. The font of date window is finely optimized to match the original exactly. The iconic “cracked dial texture” is the core highlight. Its grain is more three-dimensional than other versions on the market, especially the fine lines with super delicate workmanship.
How Is the Quality of ZF Factory Tudor Replica Watches?
Everyone knows Tudor is the sibling brand of Rolex. Making Tudor replica watches is not super hard, but it really tests the factory’s ability on fine detail polishing. Among ZF Factory’s Tudor Black Bay series, Black Bay 79730 Small Steel Shield is a favorite among watch fans. It adopts 316L stainless steel with 41mm dial size, a low-key and durable men’s replica watch. The case back follows the original closed design with fine one-way brushed finish and perfectly matched font size. The movement runs stable and accurately. Even though Tudor is not ZF Factory’s main brand, this Small Steel Shield model wins great popularity for its classic design style.

What’s the Thickness of ZF Factory Jaeger-LeCoultre Master Moonphase 13684200?
As a classic model of Jaeger-LeCoultre Master series, ZF Factory’s version delivers solid overall workmanship.
Size & Thickness
It keeps the original 39mm dial size and 10mm full thickness, fully matching the genuine watch. Few factories can get the thickness exactly right like this.

Functions
It supports real moonphase function. The date window and moonphase window at 6 o’clock are perfectly integrated. The hour and minute hands adopt a two-tone design, half brushed and half polished, totally consistent with the original design. There is a power reserve display at the 10 o’clock position.
Movement
The movement directly decides the whole watch thickness. Many other factories mess up the movement structure, making their versions 1 to 2mm thicker than original. ZF Factory selected the right movement model and optimized internal structure, achieving zero deviation in watch thickness.
