Real-replica review: 2019 new GS Factory Longines Master Collection with moon phase, comparison with the original — is it worth buying?

The Longines Wristwatch model is produced by GS Factory with a solid stainless steel case, standard case diameter and high-precision automatic Super Clone mechanism 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.
Since its launch in 2005, it has been greatly appreciated by watch lovers and has always been number one in the Chinese market in the XXX price range. Longines also put a lot of effort into this series; In addition to simple three-hand models, there are also highly complex chronographs and even retrograde versions. Although the Swiss ETA mechanism is mostly used today, that glorious past is still worth bragging about. The Longines Master Collection L2.909.4.78.3 moon phase wristwatch, introduced last year, once again attracted everyone's attention to the Longines brand. The biggest highlight of this moon phase model is that it has a completely new design language: the moon phase dial and date hand at the number 6 position are a design style that Longines has never used before. Unlike the 8-hand moon phase models, there are no extra complex functions here; everything is simplified. This design offers a more visual balance and makes the dial look very elegant and clean. This time, the size of the new Master moon phase watch released by GS Factory is 40x12 millimeters.
Overall comparison: This Master series moon phase watch from Longines maintains the look of the Master series, but is also equipped with a moon phase function. The silver "wheat grain" pattern on the dial is a great classic and extremely distinctive. Paintwork Arabic numerals are paired with willow leaf-shaped hour and minute hands; In the direction of number 6, there is a moon phase dial. When you look carefully, you can see that it has a specular (bright) treatment and a few small stars are sprinkled on it to enhance the moon phase atmosphere. The moon phase function is no different from the original; Both of them rotate once a month, and the installation and adjustment method exactly matches the original. Compared to other Master models, this series places the date dial directly above the moon phase and combines the outer wall as a single whole system. It is really difficult to distinguish between the GS and the original when we put them side by side.

Dial and Hand Details
Dial comparison: The dial design is also much more diverse. Classic silver wheat grain pattern dial, decorated with paint-finished Arabic numeral hour markers; The GS and the original are consistent with each other in dial placement. Even when viewed in the light from the side, the two are compatible like two old friends, it is difficult to distinguish the real from the replica.

Case and Body Workmanship
Detail comparison: The mold and workmanship of the willow leaf-shaped blue steel quenched hour and minute hands are the same as the original. The workmanship of the moon phase at number 6 is fine; When you look at the dial, it can be seen that it has added a lot of aesthetics to it. The moon phase has also been specularly processed. The original has a slight trace of imperfection at the 3 mark; There was no difference in the central axis of the baked blue steel hands.

Crown, case workmanship and thickness comparison: The Longines inscription on the crown is three-dimensional and clear; This area was made slightly larger in GS. In terms of thickness, the two are almost the same. The side surface of the case is polished and the lines are equally natural and fluid.

The GS restoration is spot on in all the important details of the chassis. The weight of the clock head is 5.9 grams more on the GS than on the original; The difference is small and does not affect usage.

Movement and Caliber Performance
Mechanism rear window comparison: GS does not skip any detail; The Master series has meticulously brought back the unique elegant spirit of the case, so that the wearer experiences a comfortable and comfortable use. The movement balance position of the GS is the same as the original; The workmanship and design of the automatic rotor is the newest version of 2019. Let's also look at the engraving on the case back: From the macro photos, it can be seen that the original is a little thicker.
Overall the engraving work is still pretty decent.

Mechanism detail comparison: In addition to making the dial look more harmonious and orderly, this is also a reflection of the trust in the movement production craftsmanship. The GS uses the custom-made L899 movement; All are exactly the same as the original, including major and minor bridges, balance direction and functions. When viewed through the rear window, it can be seen that the entire mechanism has undergone really meticulous processing. The fish scale pattern and Geneva lines greatly increase the viewing pleasure of the movement.

Strap, Buckle and Comfort
Strap comparison:Uses original alligator leather strap; GS used Italian calfskin. It is very soft to the touch, no less than crocodile skin, it is truly an honest choice.

Buckle: Classic butterfly buckle; It opens and closes, easy to put on. The internal workmanship of the buckle was not treated superficially and is considered to be highly qualified; The opening and closing sensation is clear and accurate. The manufacturer says it is compatible (replaceable) with the original.

General Evaluation and Conclusion
Finally, let me add a series of real shot photos, then I will give a review;

The mold and workmanship of the willow leaf-shaped blue steel quenched hour and minute hands are the same as the original.

The wheat ear texture on the dial looks like it came out of a mold with the original; It is impossible to distinguish with the naked eye.

The moon phase dial is three-dimensional and glossy.



The fish scale pattern and Geneva lines on the mechanism greatly increase the viewing pleasure.


The Italian calfskin strap is paired with Longines' classic butterfly-shaped stainless steel buckle.

The price-performance ratio is really good for a watch that is not very well-known but has such a prominent moon phase function. I think it would be much better if a 36-38 millimeter version was also released; Thus, the couple watch could be completed directly and sales would definitely skyrocket. Because now many female users can directly wear watches over 40 millimeters. I hope Longines will fill this gap in the future. Our content in this section ends here. As a final word: friends who like it, do not hesitate to add the watch store below for watch chat. See you in the next episode.
