The invention of the tourbillon is a milestone in the history of watches and clocks. In order to be able to get rid of the errors caused by gravity when the clocks travel, Mr. Boucher invented the tourbillon device. ‘Pocket watch’, and later applied to the watch with the maturity of technology and the popularity of the watch, tourbillon as one of the most complicated manufacturing process of the watch can only be seen in high-end watches. China’s most mature tourbillon watchmaking technology is Beijing Watch Factory.

 The watch series of Beijing Watch Factory has been loved by the majority of watch fans since its launch with its exquisite design and high-quality movement polishing process. Today we bring you the latest product of the series ‘Transfer FN’ ‘IV’ watch, a brief review of first-hand information.

 The appearance of the Cross-FN Ⅳ watch is different from that of the Cross-FN III watch in that the Cross-FN Ⅳ adopts a black-plated ceramic case which is more fashionable and dynamic. The dial design is the same as that of the FN III, with a power reserve display, a Chinese Lingyan tourbillon device, and a quite complex flyback calendar.

 Let’s look at the crown of this watch first. The gear-type crown is engraved with the ‘Beijing’ logo. The thickness of this watch is relatively ‘thin’, and it is still controlled at 12 with the tourbillon device. Within millimeters, it can be said that it is quite difficult, unlike other brands, which are often outside of 14 millimeters.

 The FN IV watch case, bracelet and buckle are all made of more wear-resistant stainless steel, which is more comfortable and convenient when worn.

 The bottom of the watch is designed with sapphire crystal back. The TB01-2FN movement is beautifully decorated with blue steel screws and ruby ​​red and blue. The watch is waterproof to 30 meters.

 The FN IV watch case, bracelet and buckle are all made of more wear-resistant stainless steel, which is more comfortable and convenient when worn.

The durable and wear-resistant stainless steel bracelet will be more convenient in daily wear. Due to its strong characteristics, it will not be as easy to be scratched as other materials.

 At six o’clock on the dial is the tourbillon device. The pendulum of the tourbillon mechanism resembles a Chinese Lingyan flying with wings. The carving process is vivid.

 Below the twelve o’clock position is a small dial with power reserve display. The FN IV watch uses the Beijing TB01-2FN movement, which can provide no less than 63 hours of travel time when fully wound.

 At 9 o’clock is the date display small dial. It is worth noting that this date display small dial uses a more complex ‘flyback’ design, which shows the technical strength of Beijing Watch Factory.

 The Transit FN IV watch uses the Beijing TB01-2FN movement. The TB01 series movement is the first batch of tourbillon movements successfully developed by Beijing Watch Factory. After continuous improvement, the movement becomes more stable and durable. The first batch of tourbillons in Beijing Watch Factory was successfully developed by watchmaker Xu Yaonan in 1996. After continuous improvement and optimization, the movement became thinner and more stable, and the flyback calendar function was successfully added in 2005. The pendulum splint on its tourbillon assembly resembles a flying wing that has been flying. It has a cute name called ‘Chinese Lingyan’ and it is officially called ‘Chinese tourbillon’.

Summary: At the end, we put a comparison chart of two watches. The two designs of the same movement that pass through FN IV (black-plated ceramic case) and FN III (steel case) can give you more choice. The addition of the tourbillon guarantees accurate timekeeping. The stainless steel case and bracelet material have greatly reduced the manufacturing cost. Currently, the domestic price of FN III across China is 48,000 yuan, which is a relatively high value, which can make the Many watch friends enjoy top-level production technology at great value.
