Whether it is a mechanical or a quartz watch, we traditionally have only one adjustment method-turning the crown . However, for those who strictly require precision, this action alone may cause errors. First, you have to pull out the crown when the second hand stops at 12 o'clock, and then rotate the hands to the right position; sometimes it is difficult to align the head accidentally, which is also a trouble; wait until everything is set and ready to restart When you start the watch, you may catch the wrong timing, or simply turn to the crown at the moment you press it down, so that the time that has been calibrated with great difficulty will run away. Don't worry, there is no such trouble in satellite pairing.
CITIZEN As early as 2011, it launched the world’s first watch with the world’s first precision watch case using the Earth’s satellite case. Ten thousand kilometers of satellite signals; this was a very advanced technology for the watch industry at that time. Then light time led mankind to 2018. CITIZEN is still the leader of satellite timekeeping watches. Unlike those Swiss brands that keep reminiscing about the 19th century, they dominate their path. In fact, CITIZEN has gone on this road for more than seven years, and with the foundation before 2011, it is a full 100 years, that is, counting from the creation of the brand in 1918. In order to celebrate its centenary birthday, CITIZEN launched three new limited edition F990 solar-powered GPS satellite timekeeping watches.
F990 movement is the latest solar-powered GPS satellite timing movement, continuation of the past technology, double the speed of the pointer movement under the same function, reducing the wearer waiting for adjustment The time (the fastest 3 seconds for satellite time, 0.9 seconds for the time between the main dial and the sub-dial), it can be said to be the most advanced system at present.Eco-Drive solar kinetic energy ensures that the movement that needs electricity all the time can maintain operation. Even if it often stays in a low-light environment, it is not a problem to run for one and a half years after being fully charged (five years in the power saving mode). This concept of driving time with light is the core value of CITIZEN watchmaking. Without light, nothing can be seen in the window of human soul. With light, the time in the sun, moon and stars becomes possible to calculate.
F990 solar-powered GPS satellite time synchronization watch is an extreme example. The so-called extreme is to make things the best. For a GPS watch, in addition to a precise movement, it must also be equipped with a good design and exquisite workmanship. CITIZEN uses the curved sapphire crystal glass mirror to create the feeling of a sphere, echoing the relationship between satellite time synchronization and the universe beyond the earth; a special ring of transparent glass is left between the bezel and the case, making the outer ring of the dial look like The green coil of the satellite orbit is shown on the side; the smooth-lined hollow push handle not only facilitates the operation, but also strengthens the overall modernity; the frame supporting the time scale of the dial and the transparent sub-dial at 3, 6, and 9 o'clock also highlight the rich layers .
In fact, this timepiece has surpassed the level of mid-priced watches. From another point of view, not only mechanical watches can show the so-called high-end texture, but also GPS satellite time-setting watches with solar-powered energy. The lightness of the Super Titanium™ case makes it easy to wear the watch on the hand, and the black DLC coating hardens the surface (1,000-1,400Hv, which is 8 to 10 times the normal titanium). Reduce many scratch accidents. To put it simply, this is a high-tech top GPS satellite chronograph driven by light.
