In this section, the brother will examine the ZF Factory Tudor Black Bay M79830RB-0001 GMT red-blue bezel replica watch in comparison with the original; Let's see how similar it is to the original. Will there be color difference?
Tudor Black Bay M79830RB-0001 model is produced by ZF Factory with a solid stainless steel case, 41 mm diameter and ETA 2824-2 caliber in accordance with 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.


So what is this watch really like? Undoubtedly, the market price is much higher than the list price and it is very difficult to find. However, everyone knows very well that such a popular model cannot escape the fate of being imitated within the country. This watch caught the eyes of countless people as soon as it was released; Rolex has captured almost all the headlines with its new steel “red-blue bezel” model.

When we compare the watch head, the general appearance is almost exactly the same. ZF also used an anodized aluminum bezel material, consistent with the original. Red is calm, blue is calm; The classic red-blue bezel has been recreated with zero color difference, which forms the spirit of the replica. The domed, high-quality imported sapphire glass sits in perfect integrity with the case; The anti-glare effect is also extremely good.

The thickness of the two is almost the same; It is not possible to distinguish the difference with the naked eye. The large crown with stainless steel screw is perfect size; The lines of the Tudor's iconic rose motif engraved on it are fluid and its pattern is three-dimensional. The non-slip teeth are also carefully processed, the feeling of use is very good.

The deep, inky black dial surface is exactly the same as the original; The lume filling of the hour markers and hour and minute hands is equal and smooth, you can read the time clearly at night. The “snowflake” hour and minute hands on the dial have been copied very successfully; The corners are clear and the edges are smooth. ZF has perfectly recreated the classic elements of this series. The brand logo and letter-word prints are also extremely realistic.

All four ears are produced with matte brushed workmanship; The side surfaces of the case are polished and finished, they do not sting the hand and have an extremely beautiful line aesthetic. The color tone of the unidirectional rotating red-blue anodized aluminum alloy bezel is the same as the original; “blue” has a dark tone, “red” has a wine-like tone, red and blue are intertwined and pointed out ostentatiously. The interior of the case is equally clean and tidy, revealing the great factory quality.

An exact and meticulous replica made from the original mould. The ZF factory overcame the difficulties by doing its best; It perfectly reflects the design and quality of the original factory. Original and elegant, both high quality and stylish.

The same “riveted” stainless steel strap as the original, with fine workmanship; Solid links were used, and the links on both sides were joined with rivets to create a unique stepped structure. The edges of the strap and the buckle are rounded, not sharp, comfortable in the hand. The product produced by ZF must be of high quality.

The screw-closed case back displays superior workmanship with the combination of matte and frosted texture. Each rotary tooth is meticulously machined; The corners are clean, no burrs. The engravings on the back cover have been carefully considered over and over again; Whether it is size, depth or thickness, they are all at the same level as the original.

The original uses Tudor's own MT5402 movement; ZF used the TOP level Seagull 2824 automatic movement and its functions match the original.

Below are the actual product shots of the ZF Tudor Black Bay series red-blue bezel: The diameter of the watch is 41 mm; This size looks great on both small and large wrists. The case is made of steel stainless steel and is mostly brushed finished; This reduces the overall appearance of the watch from being affected by unwanted scratches. Now it's time for the real shooting detail images; I will explain them all in detail one by one.

The red-blue bezel of the ZF Tudor Black Bay series is sapphire glass, the same as the original; The transparency of the glass is very good. ZF has been very careful throughout, the angular lines are clear and the processing is extremely successful. The red and blue of the bezel are extremely deep and unobtrusive when viewed against light; It's hard to see much difference in the color tone, the bezel has a nice reflection. The overall weight is balanced; there is almost no sound when you shake it, there are no burrs; The engraving of the hour and minute hands is also very beautifully done.

GMT is the general name for the second time zone; Therefore, this wristwatch can also be called Tudor GMT. In appearance, there is also the familiar blue-red bezel; Although red and blue seem like two colors that stand out, red is actually a wine-like tone. The classic snowflake hour and minute hands are here; The red hand serves as the GMT hand. There are 24-hour markers on the bidirectional rotating bezel: daytime 12-hour markers are printed on the wine red section, and night 12-hour markers are printed on the blue section. When they come here, many people will definitely ask: is there a color difference between blue and red? We can tell you with all responsibility that color difference definitely exists; The issue is only the size of this difference.

At 12 o'clock, there is the classic inverted triangle design. Through the sapphire glass, we can see the iconic snowflake hand on the dial suddenly dazzling; The distinctive red “snowflake” hand rotates around the dial's 24-hour markers. The bidirectional rotating bezel is engraved with 24-hour markers, making it easier to read the time in other time zones.

This arrangement, in which red and blue share the day and night equally, makes reading the time more intuitive and practical. Lume material is applied to the hour and minute hands and hour markers, making it extremely bright at night. You can read the time clearly even in the dark. There is a date window function with black text on a white background at 3 o'clock.


The lateral thickness of the case is 13 mm; The case, made of steel, has undergone careful processing and is highly textured. The case body has also been subjected to a fine brushing process; Tudor's iconic rose logo is engraved on the top of the polished stainless steel crown.

As for the back of the watch, the closed case design continues. As for the movement, a revision of the Seagull 2836 was used and a structure imitating the original MT5652 movement was used; Their functions are the same, sensitive and stable.

The watch's model number and code are engraved behind the lugs, a unique code for each watch. Since it was not a self-made movement, the Seagull 2836 was used; This causes the hour-minute hand alignment order to be different and therefore the way of setting the date to be different. When you pull out the three-stage screw-down crown one step, the date is set. In the original, the date is set by turning the hour hand, while on the replica watch, when you turn it up, the date is adjusted by skipping, and when you turn it down, the GMT hand is adjusted. In general, the mechanism remains limited.

Finally, let's look at the strap. The same stainless steel material strap is used as the original. It has undergone a careful brushing process; Its texture is extremely round and smooth. The arrangement between each pod is very tight, creating a unique trapezoidal structure. With the Tudor-specific steel folding clasp, you only need to press lightly and you can easily wear the watch; Comfortable in hand.

Summary: Today, the Tudor GMT has been worn on my wrist for 2 weeks; Let me briefly summarize the reasons why I prefer it. Water resistance becomes especially important when going on rainy, blazing, sandy trips, and the 200-meter water resistance of this GMT is more than enough. Polished and frosted riveted steel strap, domed blue sapphire glass almost acrylic-like feel, particularly smooth; Add to this the matte wine red and blue anodized aluminum bezel, and these intense retro elements give a sincere and natural feeling as soon as you put the watch on the wrist, like an old friend you have known for a long time. 41mm diameter fits the large watch fashion, lume is bright and clear, readable for a long time.
