3M Factory Longines Master Collection eight-hand moon phase wristwatch review

The Longines Wristwatch model is produced by the leading Super Clone manufacturer workshops with a solid 316L stainless steel case, 42 mm diameter and a 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.
Each character is molded one by one; text positions, font size, month, day and moon phase windows match the original exactly. The same high-end oil-filled and enamel coating workmanship as the original was used to ensure that the brightness and color tone of the dial surface are exactly the same. We acted with the understanding that the dial is the face of the watch and the result is no less than the original.
The sun, moon and star motifs on the lunar phase disc were further retouched; It shines like gold and is the same flatness and size as the original.
Case and Body Workmanship
The hour and minute hands of the original were copied exactly; Heat-treated blued steel hour and minute hands, baked using the same quenching equipment. Color and brightness are the same as the original; Most products on the market use heat-treated blue hands imitated by electroplating.
The bezel, case back and main case were molded separately. 42 mm diameter, 14.5 mm thickness; Same dimensions as the original. The brushing work of the lines, chamfers and inner case sections were both meticulously processed by hand and completed with CNC. Every part, including the screws and crown, is subjected to QE quality control one by one; Thus, the atmosphere of the original is captured exactly. Every case part is compatible with the original, so replacement is that easy.
A converted L678.2 fully automatic mechanical chronograph movement based on the 7751 was used. Each mechanism is individually adjusted and quality controlled by QE; After the watch is completed, it is subjected to a second test. Thus, the margin of error is minimized and stability is increased.
Strap, Buckle and Comfort
There are two different strap options. The steel bracelet is made of imported 316L stainless steel; It was polished and smoothed with CNC, and the back side was brushed. The reverse has the same VD steel stamp as the original. The buckle uses an 8+1 spring button, the same as the original, and the text on the buckle is exactly the same. The leather strap is made of brown crocodile skin and is soft to the touch.
Dial and Hand Details
The 3M Factory Longines Master Collection eight-hand moon phase wristwatch reflects the atmosphere of the original in every detail; If you put it in a showcase, you would not be able to distinguish it from the original.
