The Tissot Tengzhi series solar model has the following functions
Compass, timer, barometer, altimeter, alarm watch, etc.
The advantage is that it has strong battery life and simple operation, does not require external signal support and does not need to be linked to other devices.
I won't talk about smart watches.
A common mechanical watch movement has 90 to 100 parts, and a more versatile movement has 1,400. The power source of the mechanical watch is a coiled spring, which stores the energy that drives the watchmaking machine. work to achieve the timing goal. Mechanical watches can be divided into two types: manual mechanical watches and automatic mechanical watches:
(1) Manual mechanical watch: hand-winding movement, turn the crown and the movement spring releases energy. energy to push the watch works.
(2) Automatic mechanical watch: The power of the self-winding movement is generated by the weight of the flying weight in the movement. When the arm carrying the watch swings, it causes the flying weight to rotate. , and at the same time drive the flying weight into the watch. The spring winds the watch.
Features of mechanical watches:
(1) The travel time of mechanical watches is different from that of quartz watches. The second hand of mechanical watches moves continuously and uninterrupted.
(2) Due to the complexity of the mechanical movement of the watch, the error of travel time is large (depending on each brand, the error of observatory movement is smaller and the error of one day is normal). within -4/+6 seconds. The travel time error of a mechanical watch cannot be accumulated, and the watch needs to be debugged after a period of time
(3) The craftsmanship is exquisite and easy to useize. It can work for more than 36 hours. hours once fully rolled up.
(4) The movement has a long lifespan.
(5) The appearance is thicker than quartz watches (depending on each brand). Some brands are also very thin, but they are generally manual mechanical watches.
Features of quartz watches:
(1) The running time second hand of a quartz watch quartz jumps every time, and the running time is very accurate. The monthly difference should generally be less than 15 seconds. There are two types: three-. hand and two-handed.
(2) The movement uses integrated circuits, its structure is much simpler than that of mechanical watch movements, and the assembly is very simple.
(3) It is easy to use and does not need to be rolled up to carry. A battery can generally be used for 2 to 3 years. However, some watchesquartz use lithium batteries, which have a long life and can be used for about 7-8 years.
(4) Quartz watches are relatively cheaper than mechanical watches (same brand and style), but some high-end brand quartz watches are expensive because of their good brands and quality. their materials of good appearance (18 carat gold or diamonds). or precious metals). The excellent appearance design makes some quartz watches much more valuable than ordinary mechanical watches.
3. Automatic Quartz Watch: Combines the advantages of an automatic mechanical watch and a quartz watch. It requires no batteries and the user can choose to wind it manually or recharge it automatically. Its electronic quartz device makes it more precise, with a monthly error of less than ten seconds. Its operating principle is to use the swing of the arm todrive the rotation of the flywheel gear in the watch to generate energy to drive the internal micromotor into energy, thereby providing sufficient power for the quartz device in the watch, and excess power.Energy is stored by microcapacitors for later use. When the watch is fully charged, it can work continuously for more than nine days without having to wear it on your wrist. At present, Swiss Tissot watches and Japanese Seiko watches are both well-known automatic quartz watches.
4. The working principle of the photokinetic energy watch: firstly, the light energy is converted into electrical energy through the solar chip, and the electrical energy is stored in a recyclable titanium lithium-ion rechargeable battery. , then the electrical energy emitted by the battery is integrated. The circuit generates a pulse signal to the bobine and generate magnetic force to drive the stepper motor, converting electrical energy into kinetic energy, driving the gear to rotate, and driving the pointer to indicate the After being fully charged, it can work in the dark for about 40-180 days, with accurate travel time and long battery life.
