Hello everyone, this is bokeytime. Today, I’d like to introduce to you a Tudor Black Bay Professional GMT series model, the M79470-0001, from the ZF factory. The style of this model is somewhat similar to the vintage Rolex REF.1655. After all, as a sub-brand of Rolex, Tudor can understand the intention behind launching this model. Without further ado, let’s take a look at the performance of the Tudor Black Bay Professional M79470 from ZF Factory.

First, let’s take a look at some detailed comparisons between ZF Factory and the genuine product:
Comparison of dial details: ZF Factory has restored all the details on the dial very well. The font size of the LOGO, the luminous scale pins and the date window can all reach the level of being indistinctly realistic.
Pointer details: Due to the different structures of the movements, the central axis pins of the hands from ZF factory are slightly higher than those of the genuine ones. This should be regarded as the biggest drawback when comparing the entire watch. However, when the movement is installed on the hands, the only identifiable appearance is the central axis of the second hand. The central axis of the second hand from ZF factory also achieves the same size and thickness as the genuine ones, with the same axis slightly raised and a consistent sandblasted texture. The final installation effect is still impeccable!

Calendar comparison: Even the calendar ring has to be compared. ZF Factory is unique in the market. True gold fears no fire. Even the most inconspicuous hidden details are exactly the same as the genuine product, with the same arrangement and background color. Trust ZF Factory and buy with your eyes closed without worrying about losing.

Case details: After removing the internal organs, we compared the case case separately. ZF Factory can capture every detail and strive to clone a brilliant work. The font of the engraved characters on the bezel is synchronized, the metal brushing reaches the fineness of the genuine product, the curvature and size of the lugs, and even the width of the chamfers are all accurately reproduced. ZF Factory can be called a detail maniac.

Case comparison: The curvature of the case shape is very similar, and the thickness data and all the details of the case cover are exactly the same. The classic Tudor plum blossom relief on the top is three-dimensional and clear, which can be said to be printed in the same way, making it hard to tell the real from the fake.

Bottom cover comparison: The engraving, depth and coordination of the bottom cover from ZF factory are very close to the original, not at all inferior, and the craftsmanship is exquisite. The chemical properties of high-hardness steel are very stable. To carry out deep operations on it, a lot of time and multiple processes are required, and the entire process is long and complicated. Note: The original font on the back cover is from a second-hand watch. It looks rather gray because of dirt.

On the back of the case: The encoded characters at the two lugs are hard to distinguish as genuine or fake even when magnified to a macro lens. This shows that the watchmaking level of ZF Factory has been upgraded to world-class standards. It is no exaggeration to say that it is a top brand in the imitation watch industry.

Strap comparison: The stainless steel strap is in sync with the genuine product in terms of thickness and structure. It is equipped with a safety clasp, and each component of the strap is independently detachable, just like the genuine product. The safety lock-in clip at the head position has also been accurately replicated. ZF Factory has truly put in a lot of effort.

Clasp comparison: The stainless steel case is exactly the same as the whole. The inner side engraving uses the same stamping process as the genuine product, and the edges are neat and tidy. What’s even more amazing is that the quick adjustment structure for the strap length is completely replicated. Whether it is the opening position, the spring force or the adjustment feel, they are all exactly the same as the genuine product.

How does the ZF factory Tudor Black Bay Professional GMT series M79470-0001 perform in terms of details?
Tudor’s unique dial design uses radiation-free Super-Luminova luminous coating to make the entire scale pins. Without a metal frame, it appears more simple and the luminous effect is brighter. In addition to the regular display of the local time, this watch is also equipped with a GMT function, which is indicated by a longer yellow snowflake hand and a 24-hour fixed scale outer ring. The instant jump calendar at the 3 o ‘clock position is synchronized with the independently adjustable hour hand, which is very practical in daily life.


The 24-hour bezel adopted by the new product, except for slight differences in font and other details, can be said to be exactly the same as the Rolex Ref.1655 in all other aspects, including the character spacing and the brushed effect on the bezel, which have been perfectly restored.
ZF brings more joy to many Rolex enthusiasts who love vintage Rolex!


ZF Factory dares to be the first to achieve the “reincarnation” of the antique Rolex – the Tudor Black Bay Professional watch has an ultimate comfortable size of 39MM. The stainless steel case is treated with two processes: brushed on the front and polished on the sides, which is also the consistent case treatment method of Rolex.

It is worth mentioning that Tudor has also redesigned the crown of this watch. It is level with the middle case and hides the crown shaft, making it easier to grasp and adjust the time.

In addition, this wristwatch is equipped with a new “turtle-back” clasp of Tudor’s “T-fit” quick-adjustment device. This device has five holes and the adjustable length can reach 8 millimeters, which can meet the more comfortable wearing experience of watch enthusiasts with different wrist sizes.
