Tudor Black Bay M7941A model is produced by ZF Factory with a solid 316L stainless steel case, 41 mm diameter and ETA 2824-2 caliber in Swiss norms architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.
Case and Body Workmanship
On the exterior of this new ZF Factory Tudor Black Bay model, the most vibrant red ring is used as the bezel, and the case is also made of 316L stainless steel. Combining advanced watchmaking technology with a new aesthetic approach, this latest model of the Black Bay series brings together many improved design elements. Now let's take a brief look at this newly released Tudor model on the ZF Factory official site and see whether it reaches the high level of quality compared to the original.
The polished angles are extremely eye-catching; The red bezel that accompanies it carries a connotation of abundance and happiness. Also, this bezel is different from the bezel of the Rolex water ghost: the Tudor bezel has a slight sandblasted texture. ZF Factory has worked many times to achieve similarity to the original and has managed to achieve the same feel and quality as the product in the store. When you hold it in your hand, the tactile sensation makes it difficult to distinguish the real thing from the replica. Moreover, the color tone is close to burgundy, not a bright red.

The overall diameter of the watch is 41 mm. The Black Bay series has 37-39 and 41 mm options; This diameter is very suitable for Asian wrist size, a really user-friendly design. The shape of the outer line still maintains the strong performance of diving watches. Even though it is a brand under the umbrella of Rolex, there is a certain kinship in the model; ZF Factory produced the entire case form by purchasing the original for the Tudor Black Bay and making its mold.

A single adjustment crown is designed on the right side; It is processed precisely and has no flaws that could cut the hand. The entire structure of the dial can be seen through the glass, and the most important thing is that the surface of this dial has been reproduced faithfully to the original. High permeability blue sapphire glass was used as glass. Inside the dial, there are snowflake hour and minute hands and round dot markers that provide distinctiveness. The antique copper-tone coating of the dial is made with good workmanship and is made entirely of matte black material.

Decorated with golden inscriptions and minute path; The round dot signs have a metal frame. The lume material inside is placed on gold-plated hour markers with Super-LumiNova coating and appears to be a sort of rust green tone; This adds a traditional flavor to the retro atmosphere of the Black Bay series. Black Bay with ZF Factory red bezel has preserved its usual craftsmanship; From the reproduction of the dial to the printing and coatings, it is all done with the highest level of craftsmanship and is essentially 98 percent faithful compared to the original.

Dial and Hand Details
The hour and minute hands are Tudor's official snowflake design; You can see ZF Factory's craftsmanship here. The structure of the hour and minute hands is identical to the original; There are no flaws in their length and width. Especially the antique copper plated center shaft, extremely soft and smooth after polishing and processing. The middle point of the solid center shaft is hollow and relief-shaped; You won't find any burrs. The inverted triangle at 12 o'clock reveals the brand with the Tudor logo and text with a strong three-dimensional feeling.

Movement and Caliber Performance
As for the movement, ZF Factory used the Seagull 2824 movement with modifications; An empty date level has also been added, but the time setting method is the same.

The overall appearance of the dial not only reflects the classic design of the ZF Factory Tudor Black Bay, but also gives a fresh feeling, especially when this new Tudor model is worn. The strap part is offered in a five-link bracelet model and has a very unique graduated structure; but the ZF Factory official site uses artificial rivets and solid joints, the same as the original. The buckle part is designed even more user-friendly; It comes with a T-fit quick-adjustable buckle as standard, combining a retro look with an innovative design.
