In addition to the design full of respect for women, the interior is also very connotative. The limited edition xC Xu Di 202 1 of Citizen City adopts the optical kinetic energy radio wave timing technology. First of all, talk about optical kinetic energy. Optical kinetic energy is the exclusive registered trademark of Citizen, and its research and development is still in the leading position in the industry, leading the industry standard. Citizen's light kinetic energy is unique, which can transform visible light source into the power of watches, and it can be charged as long as there is light, even if it is weak light. Not only that, this watch also has a variety of radio wave functions. That is, it can receive the standard time radio signal sent by the radio tower, obtain data such as time and calendar, and automatically correct the time and date of the watch. In order to avoid the influence of smart phones or other electronic devices on radio waves during the day, the radio meter in Citizen will automatically receive radio signals at midnight to adjust the time and date, which is very convenient and reassuring. And Shu Bo, the king of Citizen? Titanium is skin-friendly, low-sensitive, corrosion-resistant and wear-resistant. It is 40% lighter than stainless steel, but its hardness is five times that of stainless steel. To sum up, the performance of Citizen xC women's watch series is needless to say, which is environmentally friendly, convenient to charge, accurate and reliable, and rich in functions. Moreover, Citizen xC series is also the number one selling women's watch in Japan, which can satisfy the picky cherry blossom girl. It can be said that all aspects have achieved the ultimate. Forget it, I want to pull the grass.
