Watch Review: All the Details You Want to Know About the GF Factory Jaeger-LeCoultre Master Moon Phase with 925 Integrated Movement

On the front, the most intuitive feeling of the moon phase of the GF 925 integrated movement is that the literal sunburst pattern is more delicate and textured than that of the previous 9015 movement version. One point to mention here is that the drawing process of GF Factory’s Moon Phase Master is very delicate, which is much better than that of the big manufacturers of the same product and grade in the market, unlike other factories that look too blunt and deliberate!

The entire mirror surface is made of sapphire crystal glass and has been treated with an anti-glare process to make it very transparent.

The Jaeger-LeCoultre logo printed at 12 o’clock on the dial is also plump and three-dimensional, clean and stable.

The hour marker batons are polished, and like the genuine version, each baton has three polished surfaces with no variation in length. The installation also matches the design of the authentic model, with the tails slightly upturned for a subtle raised effect.

When you investigate carefully, you will find that its hour and minute hands are half sandblasted and half polished, which is particularly textured, and this effect is made on such a small hand that other small factories can’t do. Moreover, the second hand and minute hand are bent downward to synchronize the original design, including the hand center axis, the hat shape here has also been made, and the details are quite in place.

The central axis of the date hand at six o’clock has also been upgraded to a concave one, which is also exactly the same as the original, and there is no longer a fake phenomenon like the previous 9015 calibre version.

Here’s a brief look at why GF is worth starting!

In the replica market, there are currently three factories that also use the 925 integrated movement for the Jaeger-LeCoultre Moon Phase. The first to adopt the 925 integrated movement was the YL Factory. However, the YL Factory’s model has issues with a flat moon phase disc and poor gloss, which is similar in effect to the ZF Factory’s moon phase disc. Therefore, it has not been recommended.

The next step is the moon phase of the integrated movement version launched by the AZ factory, which is literally a fake problem at a glance, the literal radial pattern is too thick, simply put, the texture is poor and rough, and the genuine radial pattern is very delicate, just like the GF moon phase, the az moon phase and the GF moon phase are very clear and intuitive to compare. The curvature of the literal edge is more deliberate, the excessive is very unnatural, and the traces are more obvious, while the GF factory is excessively very natural, just like the genuine product.

The moon phase of the AZ factory, the moon phase disc of this factory is made by the process of patching, and the three-dimensional sense is made, but it is still lacking, the genuine moon phase disc is a little metallic, and the AZ moon phase disc is like the texture of plastic spray paint.

Let’s take a look at the moon phase disc of the GF factory, first of all, the material of his moon phase disc is made of metal sheets, the material is already correct, and then the moon is carved out by laser engraving, we can see through the picture below that the end of the second hand passes through the moon phase disc to form a reflection, as bright as a mirror, full of three-dimensionality.

Another point is that the middle of the genuine moon phase disc is a little convex, like a convex lens, and GF Factory Moon Phase has also done this detail. In addition, the GF Moon Phase 925 calibre version has also made a slight upgrade in the moon phase disc, and the moon phase edge is not as obviously concave as before, and it is visually closer to the original.

Through the comparison of these points, GF is the only factory on the market to achieve the same effect as the original moon phase disc in the details of all the factories on the market.

Functionally: the moon phase rotates once a month, in addition! The cycle change of the moon phase function of the upgraded calibre 925 is also in line with that of the original. First of all, we press the left button to adjust the moon phase through the gadget that comes with the table, for example, today is the twentieth day of the lunar calendar, then we will first adjust the moon phase to the middle, and then press it forward 5 times, which is also a relatively simple adjustment method

The entire case is crafted from 316L stainless steel and features a large area of polished finishing. Unlike brushed craftsmanship, it is less wear-resistant, so daily wear and use require more attention. The left button is the moon phase adjustment button, while the right one is the calendar adjustment button.

The straight-pulled handle, through the lens, you can see that the texture of the handle is the same size, including the top with the Jaeger-LeCoultre logo engraved on the top is also the original version, and the JL brand embossing is also highly consistent.

The GF Factory Jaeger-LeCoultre Master Moon Phase with the 925 integrated movement version has been measured to have a case diameter of 39mm and a thickness of 9.8mm, consistent with the original. It is also highly suitable for formal wear, exuding the charm of a gentleman’s wristwatch. The ultra-thin case of this Jaeger-LeCoultre Master Ultra-Thin Moon Phase watch imparts unparalleled wearing comfort and a delicate, understated elegance.

The case back features a transparent design with clear and sharp engravings on the edges. Through the high-definition sapphire crystal, the entire structure and operation of the movement can be clearly observed. The GF Moon Phase 925 integrated movement is directly manufactured by Dandong Factory with custom molds, offering a power reserve of approximately 40 hours and high precision, with a comprehensive daily error of about 8 seconds.

So let’s talk about the movement is the key, the first point is that this 925 integrated movement, not some watch manufacturers advertise the two-way winding, Bo Ji is actually hand-debugged, and the genuine product is the same one-way winding, but its noise will indeed be much smaller than the 9015 movement, mainly in the transmission wheel has a small design, there will be resistance when idling, so it will not easily produce noise. If you have the original product in your hand, you can also check whether the barrel will follow the rotation by swinging the rotor to know if it is a one-way upward winding.

Let’s take a look at the structure of the movement, the whole movement structure and the parts of the original movement match up to more than 95%, the shock absorber is the same as the genuine KIF shock, but the balance cruise ship still uses the card degree, the genuine product is non-card degree, this GF moon phase copy has an additional adjustment error of the outer pile, which is also one of the flaws in the movement.

The engraving on the movement is clear and powerful, and the rotor is made in a special colour scheme of karat gold, rather than ordinary red rose gold. The size of the gyroscope is also up to the genuine product, which can be universal and genuine.

The barrel will rotate while manually winding the watch, which can be understood by referring to the video below.

In terms of the clasp, it adopts the original Jaeger-LeCoultre folding clasp. The LOGO on the clasp also uses an inlay process, which is very firm and solid.

The disassembly and installation method of the buckle is also synchronized with the genuine product, and you only need to lift the middle and move it down to remove it when disassembling.

The strap is the same as before, using calfskin with crocodile skin texture, the softness is OK, but the texture is worse than crocodile leather.

In terms of price:

At present, GF factory is selling two movement version configurations, one is the 925 integrated movement, which is the one evaluated today, and the other is the previous 9015 movement, the price is 300 cheaper than the 925 integrated machine, and the appearance is the same as before, but the movement is upgraded to the 9015 movement of the Dandong factory. Friends with sufficient budgets still recommend buying the 925 integrated movement version, after all, the movement advantage is there! In addition, on the 925 integrated movement version, there are also YL factory and AZ factory moon phases on the market, the price is three or five hundred yuan lower than the GF factory moon phase, it is recommended that cousins look for the details of the GF factory when buying, mainly the radial pattern of the disc surface, the edge of the concave is too flat, and whether the moon phase disc is like a mirror.
