Bokey TimeHello everyone, this is Bokey. In this watch review, I will share with you the Jaeger-LeCoultre Master Ultra Thin Series Q4018420 from ZF Factory. This is a replica of the model officially launched by Jaeger-LeCoultre in 2020. I believe many watch enthusiasts will get a sense of retro charm at first glance of this watch. Now, let’s briefly discuss the specific craftsmanship details of the ZF Factory Master Ultra Thin Date Q4018420 and see how high its simulation accuracy is.
Genuine parameters: Jaeger-LeCoultre ultra-thin master calendar watch series Q4018420 watch, price: 55000
On the front, the ZF factory ultra-thin calendar master uses a silver dial design, and the disk surface is also treated with radiation patterns. Because the shooting light is relatively strong, the radiation patterns are also more delicate, so it looks whiter.
Looking at it from another angle, we can see that the dial has a silvery texture and a delicate radiographic pattern.
The watch mirror is made of sapphire glass. This one is not coated with blue film, and the overall appearance is also very transparent. In addition, the edge part is also relatively transparent, and you can see that the scale of the dial is reflected on the edge.
The details of the disk, the Jaeger-LeCoultre LOGO “JL” below 12 o’clock, is inlaid with metal, which looks very three-dimensional and has a high gloss.
The pointer is also a genuine new design, not directly using the yin and yang needles of the old master or moon phase master. For example, the old craftsmanship is polished and frosted on one side, while the yin and yang needles of the new master Q4018420 this time use the process of polishing and drawing on the other side, and the drawing lines are also relatively thick, which looks more linear. The second hand adopts the burning steel blue process, which is very charming when blue and black, and the central axis is also designed to be hollowed out white.
The ends of the minute hand and the second hand are also synchronized with genuine products for downward bending. This design is mainly for more accurate reading time.
The calendar window is also treated with small steps, and the outer frame is a polished metal frame. The calendar font of the ZF factory master is relatively large like the genuine product, filling the entire calendar window.
The scale nails are also made with horns, the polishing process is also very in place, and the nails are close to the dial, which is also genuine. The luminous point behind the scale nails is also relatively full and three-dimensional.

The watch is made of 316L stainless steel. According to the actual measurement of Bokey, the diameter of the ZF factory’s ultra-thin master Q4018420 is 40mm, the thickness is 9.0mm, and the genuine data is 40 * 8.7mm. There is only a 0.3mm gap in thickness, a very small gap.
Let’s take a look at the workmanship of the case. The side of the entire case is treated with a wire drawing process, which looks very delicate. Several lugs are also modified with water chestnuts and polished.
On the other side is the time-adjusting head, with the brand logo of Jaeger-LeCoultre engraved on the top of the head, and the lettering is relatively clear. In terms of functions, it is simple to wind up directly, pull the first gear to adjust the calendar, and the second gear to adjust the time. The operation method is very simple.
The back cover is designed with a transparent bottom, with sapphire glass in the middle. The upper and lower parts of the edge are also frosted, and they are also embossed lettering, but the three-dimensional effect is slightly worse than that of the genuine one. In terms of movement, it is equipped with an 899 movement made in Dandong. Although the ZF factory advertises that it is an 899 integrated movement, in fact, compared with the genuine movement, the simulation is not so high. We can see that its automatic winding wheel is larger than the genuine one, and the structure will be slightly different. However, the lettering on the deck is still relatively in place, and there are also some fish scale patterns under the balance wheel, and you can also see the running process of the barrel when winding. In addition, the color of the automatic tuo is still a little different from the genuine one.
The strap is made of golden-brown calfskin, which looks very thick as a whole, but it feels relatively soft, and there is no need to change it to alligator leather or anything. The original is also made of calfskin.
The back also has brand lettering and coding, and it is also a quick-release design.
The clasp is still the classic Jaeger-LeCoultre folding buckle. This button has been applied to the previous moon phase masters and ultra-thin masters. The overall workmanship is good, and it is also a quick-release design.
For reference to the picture, Bokey has a wrist circumference of 15.5cm, which is very durable.
Summary: The new replica watch of Jaeger-LeCoultre Ultra-Thin Master Q4018420 launched by the ZF factory this time is not fake at first glance in terms of the reduction of the front appearance, and the overall workmanship texture is in place. The only thing missing is the simulation of the movement. Of course, the flaws do not hide the flaws. Friends who do not care about the flaws of the back movement are still worth buying a piece!
