The dials of the 3K factory have been upgraded everywhere文章源自高品质复刻手表-https://www.bbtwatch.com/en/dj/109281.html
The original, authentic “Clous de Paris” hobnail dial features a pattern that radiates from the center outwards. The hobnail pattern changes in light and shadow and creates a dynamic effect at different angles.

The inner ring of the dial is the minute track, and the outer ring is the hour marker ring (the overall is equivalent to the original authentic product).文章源自高品质复刻手表-https://www.bbtwatch.com/en/dj/109281.html
3: The outer ring with Roman numeral hour markers features a radiating sunburst guilloché decoration. (The Roman numerals/stroke thickness/tips/serifs are all perfectly consistent.)文章源自高品质复刻手表-https://www.bbtwatch.com/en/dj/109281.html
At 4:7 o'clock on the dial, there is also a Cartier English invisible signature (after upgrade, the invisible signature is indistinguishable from the genuine product under a 50x magnification).

The pallet fork center shafts are all independent. The center shafts have undergone secondary processing and polishing. The white sleeve on the outer ring is rounded and its height is quite prominent. (Center shaft sleeve upgrade) The technical key is to precisely control temperature and time. Insufficient time or temperature is not enough to produce perfect tempered blue hands, resulting in an extremely high scrap rate and a geometric increase in cost, making it difficult for ordinary small factories to produce. During the tempering process, time and temperature must be carefully controlled. After the hands are heated to the appropriate temperature, they will develop a brilliant blue-black color after a certain period. This color exhibits varying shades of metallic blue-black depending on the light. Under a high-power microscope, an oxide blue layer can be seen formed on the surface of the steel hands. After tempering, passivation treatment is required. If not done properly, the tempered blue layer can become too active and cause rust.

The stainless steel case has a diameter of 42mm and a thickness of 13mm, featuring a sapphire crystal with super luminous effect and water resistance up to 50 meters. The case body and inner sleeve are precisely engraved by CNC equipment for a perfect fit. (Seamless fit equivalent to the original authentic product). The Ballon Bleu features extensive polishing on the case. The back is brushed. It appears very bright under the light, especially the “flying saucer” shaped crown. The advantage is its strong sense of luxury. (The tactile feel, visual appearance, and touch are consistent with the original authentic product).

3K Factory Steel Strap Upgrade: Adopting craftsmanship consistent with the genuine product, the strap is made using a pointed-tip CNC processing method for a secure connection and to prevent gaps. The H-shaped strap links are finely polished for a textured feel. The spacing between each link is precisely calculated to match the original. The chamfering of the all-steel pins is identical to the genuine product, with meticulous attention to detail. The overall side curvature and connection have been upgraded to genuine product quality.文章源自高品质复刻手表-https://www.bbtwatch.com/en/dj/109281.html
