After GS dismantling, the same number of parts as the original are preserved.

The GS uses sapphire crystal glass like the original; The mirror surface is clear, bright and wear-resistant.

A tiny clock; It contains many complex functions such as moon phase, chronograph, full calendar display and 24-hour clock. Moreover, the sequence of all these functions is regular and not complicated at all. Original on the left, GS on the right; It is difficult to distinguish the real from the replica.


The crown part is the same as the original in size and shape. The stainless steel crown with anti-slip texture design gives a good feeling in the hand and does not slip during use. Each tooth edge of the crown crown is polished, the corners are softened and does not sting the hand. The LOGO engraving font on the side is exactly the same, the three-dimensional feeling is also very good.
When measured with precision measuring devices, there was only 1 mm difference between the GS and the original; This is a negligible margin of error.

As for the dial part, let's mainly look at the inner shadow of the dial and the engraving inscriptions. GS Factory has processed the dial in the same proportion and size, from small hour markers to Arabic numerals; The engravings are clear and rival the store quality. The wheat grain texture on the dial surface of the GS is extremely fine; The grooves are clear and smooth. It can also present subtle light-shadow changes in different lights, just like the original. GS on the hour markers on the large and small dials; The arrangement, font, spacing and ratio are synchronized with the original, no difference is visible. Finally, let's look at the date window; The corners of the date window opening are the same, the date writing style matches the original, and the day and month positions are centered.

The hour and minute hands of the GS are steel hour and minute hands, annealed to blue, as in the original; It was forged using today's high standard production technique by quenching it at 300°C high temperature. There is no major problem with the “LONGINES” lettering and the Longines logo on the GS. GS uses high-end oil filling, glaze coating and gilding process like the original; Thus, the brightness and color tone of the dial surface are ensured to be consistent, and the result is not inferior to the original, but even exceeds it. There is also no problem with the orbital texture and engraved inscriptions on the small dial of the chronograph hour hand.

GS opens the exact mold and disassembles it; The bezel, case back and main case were produced independently and the same dimensions as the original were preserved. Every case part is in original configuration. Whether it is interior or exterior workmanship, everything is meticulous and meticulous. It is impossible to find fault with the position and size ratio of the chronograph pushers and the crown cap. The chamfering angles in the position of the ears are exactly the same; The inclination angle and height are compatible, the polishing work has been done meticulously.


The steel bracelet uses a three-section printed clasp. The LOGO and the English engraved text on the buckle are exactly the same; The meticulous processing of fine details reveals the spirit of craftsmanship of the GS. Fully compatible with the original, no problems whatsoever. The buckle uses 8 1 spring buttons as in the original, and the logo engraving on the buckle is also very finely processed.

The issue that watch lovers are most worried about when it comes to the open case-back mechanism design is whether or not it will be obvious that it is a replica at first glance. The open case back of the GS remains essentially the same as the original. The original L687.2 movement was modified and based on the ETA7750. The GS Longines Master eight-hand moon phase watch uses the Shanghai 7751 movement; This movement is a development of the ETA7750 movement, which was the earliest imported from China years ago. The 7751 movement has additional month, day and moon phase indicator functions compared to the 7750, and is structurally very close to the original. When we look carefully, the stone color of the shock absorbing floor of the GS is slightly darker red than the original; The middle shaft of the rotor is a slightly lighter color in the GS. Of course, these are differences that can only be seen when the mechanism is disassembled and placed side by side with the original.
