If you?] Followed by the fire, you still have to do it, and you can't bend it. All of the girls are happy, but the girls are still watching the brand. Zara, a brand introduced in the first quarter of the season, has launched a new series of L-flavors in the 1970s, including foreign brands, streaming products and suede products.

New Arrival is the new watch is the direction that we combine with the current latest fashion watch trends in the world, and comprehensively develop our latest products. The new watch is a combination of contemporary art and contemporary technology.
According to the different oscillators used in watches, mainstream watches on the market can be divided into the following two types:
1. Mechanical watch: a watch adjusted by a mechanical oscillator.1. Manual mechanical watch: It adopts a hand-winding movement. The mainspring whose head is the movement is fully wound by turning the watch. When the mainspring is fully discharged, the gear is driven to run and the pointer is moved to move the time.
2. Automatic mechanical watch: The self-winding movement is driven by the weight of the oscillating weight in the movement, but the swing of the arm wearing the watch will drive the oscillating weight to rotate, and at the same time drive the mainspring in the watch to wind the watch and push the time.
2. Quartz watch: a watch adjusted by an electronic oscillator-a quartz oscillator.
1. Digital quartz electronic watch: a watch that combines the piezoelectric effect of quartz crystal and a bipolar liquid crystal display, and its function is completely completed by electronic components.
2. Analog quartz watch: The energy of the quartz watch comes from the silver oxide button battery. After the silver oxide button battery provides a specific voltage to the integrated circuit,
The oscillator circuit and the quartz resonator are used to vibrate the quartz oscillator to form an oscillator circuit source. The electrical signal output from the oscillating circuit enters the frequency divider circuit and then divides the frequency to generate a pulse signal, and then passes through the narrow pulse circuit to output the pulse signal and enters the drive circuit for amplification, and forms an alternating bidirectional pulse signal, thereby driving the stepping motor to operate The intermittent rotation further drives the transmission gear train to make the hands accurately display the time.
3. Automatic quartz watch: It combines the advantages of automatic mechanical watch and quartz watch. It does not require batteries, and the wearer can choose to wind it manually or automatically recharge. Its electronic quartz device makes it more accurate, and the monthly error is less than ten seconds. Its operating principle is to use the dancing of the arm to drive the pendulum in the watch to rotate and generate energy to drive the internal micro-motor into energy, so as to provide sufficient power for the quartz device in the watch, and the excess power will be stored by the micro-capacitor for backup . When the watch is fully charged, it can run continuously for more than 9 days, and there is no need to wear the watch on the wrist.
4. Solar energy watches: Firstly, solar energy chips are used to convert light energy into electrical energy, and the electrical energy is stored in a recyclable titanium lithium ion rechargeable battery, and then the electrical energy from the battery generates a pulse signal to the coil through the integrated circuit. The stepping motor is driven by magnetic force, which converts electrical energy into kinetic energy, pushes the gear to rotate and drives the pointer to indicate the time. After fully charged, it can run for about 40-180 days in the dark, and the time is accurate.
