Shared by our watch friend: ZF Factory Tudor Black Bay red

Tudor Black Bay M79830 model is produced by ZF Factory with a high-tech ceramic case, 41 mm diameter and ETA 2836-2 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.
The watch was pretty dirty when I opened the package, so I soaked it in a bubble bath.
Water resistance [checked]



I start examining the watch. I will make the comparison based on the following items (gen represents the original, rep represents the replica version):
1. Case:shape, surface finish, crown, steel color, lines, lug shape.
2. Logo, hour and minute hands, date, colors.
3. Bezel and dial surface:font, colour, functions and bezel teeth.
4. Strap:feel, polished and finish comparison.
5. Case back
font, spacing, logo, inner ring vs gene comparison, back tooth comparison.
6. Lume effect.
7. Movement:functions, power reserve, sound.
1. Safe
The structure is flawless, the lines are clear. All brushed and polished surfaces look like the original. The lines on the bottom and top of the case profile are very beautiful.


The ears and polished surfaces are just like the original.

The appearance and shape are correct; There is no gap in the replica version, it is the same as the original and has the groove structure. If you don't understand what I mean, look at the photos.

The replica version is even better made than the original; Tudor has some space between the ears, if you look where the gen ears are you will see there are little spaces there.

The thickness of the original is 14.6 mm, while the replica is 14.7 mm; The case size is 41 mm and is exactly the same as the original. My wrist is about 16 cm, my wrist is considered thin here, but when I wear it, it fits perfectly. I went to work with him today.

The proportions are absolutely perfect; It weighs 141g, just like the original.
The crown is just the perfect size; When viewed from different angles, the crown teeth of the real thing are perfect.


2. Logo, hour and minute hands, date, colors.
Everything is perfectly aligned throughout the dial; The shield logo is aligned with the 12 hour marker, as well as the bezel triangle at 12. Snowflake hour and minute hands are perfect, the logo is extremely clear.


A modified movement on the Sea-Gull 2836 is used for the GMT function; The GMT hand is positioned below the hour hand.
The feel is excellent, the color is perfect, the GMT hand extends to the outer bezel and is consistent with the original. The seconds hand reaches the round hour markers on the dial, which is accurate. All the hash marks on the clock are just like the gene.
Font size appears consistent in the date window; A perfect window of history.


3. Bezel and dial surface: font, color, functions and bezel teeth.
Feel: The bezel feels very comfortable when rotating, the touch is nice. The Tudor shield logo with its 12 position is perfectly aligned.


4. Strap: feel, polished and surface comparison.
The serial number and steel type are written on the bottom of the watch. I think it's pretty well etched.


There is a ceramic ball on the buckle to keep its position stable. Everything is correct.



The Tudor logo is embroidered in a perfect font on the buckle. Only the top of the hook isn't quite right, but that's a very minor detail; It's a small problem that no one will notice unless they pick it up and look at it enlarged.

The middle links are also polished correctly.
I checked the font on my own watch; all correct and where it should be, [shield emblem] caliber production…
Serial numbers on both sides of the ears
The diameter of the inner and outer ring is corrected correctly, the rear teeth are also corrected.


6. Lume: shines brightly, just like a fully charged Thor.
It's still visible even in bright room light. It fades quickly in sunlight but remains bright throughout the night; I could still see the glow when I woke up in the morning. Lume is evenly and accurately applied to all hour markers, hour markers, seconds hand, and GMT hand.

7. Power
In the original, the GMT hand is above the hour hand, in the replica it is opposite. The manufacturer made a statement about this. Function: You loosen the crown by turning it counterclockwise and you can wind the watch. First stage: turning it clockwise adjusts the date, turning it counterclockwise adjusts the GMT hand. Second stage: adjusts the time including the hour, minute hands and GMT hand. Sound: it doesn't have a loud rotor noise but it does click like other Asian mechanisms. Mechanism workmanship: unknown; Since I cannot open the case back, I am not sure whether it is processed or not.

My conclusion is this: the overall impression is very good; I recommend anyone interested in Tudor to try this watch. It doesn't have a strap that feels cheap, it doesn't have sharp edges, it has a very unique matte textured dial.
I hope you like my review. Thanks!
