Watch is a fashion symbol of our people, and now there are a lot of young people began to like it and wear it, because the watch on the modern production technology and development process, is more than a more precise timing tool has the strong adornment effect. Some people say that people with the table but few see table, but I personally don't think so, accustomed to is a kind of dependence, good nonsense not say back to to share some of the common problems of the clock.

1. The observatory certification traveltime error of mechanical watches should be?
Answer: the error of + 6 seconds to 4 seconds.
2. The average error should be a mechanical watch?
Answer: slow pendulum table for the day of error of plus or minus 45 seconds; Put table for the day of error of plus or minus 0 seconds faster.
3. The error should be quartz watches?
A: quartz watch error of plus or minus 15 seconds.
4. Why is quartz watch is much more accurate than walking mechanical watch?
Answer: the precision of the quartz watch is a quartz oscillator as the carrier, the precision is fixed in the circuit, is not affected by the outside world. And mechanical watch is a balance wheel balance spring system for controller, will be influenced by the outside world, lead to unstable as well.
5. The theory of the button battery use time?
Answer: the theory of using time is one year, silver oxide batteries, generally use two years or so, zinc, manganese, lithium batteries use time is shorter.
6. Why the watch under the normal use will suddenly go fast?
A: maybe it's because the watch is affected by the strong magnetic field, the hair spring produced by the magnetic adhesion, will not operate properly. So watch in 7. How to recognize the watch by magnetic? Are magnetic?
Answer: when the watch suddenly walk fast, under normal use for a few minutes or a few hours, you should consider whether the magnetic. By magnetic after watch should be immediately sent to a professional qualification watch maintenance organization for testing, and the demagnetization for demagnetization instrument, can be restored to the original precision as well.
8. Quartz watch in long-term need not how to place can save electricity?
A: quartz watch in the crown should be pulled out when not in use for a long time, let the watch is at a standstill. Watch in the design of a power device can achieve the result of energy saving.
9. Why don't the long-term use of quartz watch battery will regularly change?
A: quartz watch battery generally work time is about two years, with a calendar week, moon and stars, such as the attachment table, travel time may be shorter. So even if the place don't have to keep 2-3 years to replace a battery, or batteries are prone to leakage, electrolyte can produce corrosion to the circuit board, so watch scrap.
10. Mechanical watches why maintenance regularly?
A: mechanical watches, after long-term use of environmental pollution, moisture, erosion, the movement of the internal operation of dry metamorphic effect lead to wear and lubricating oil watch parts wear corrosion, work properly. So regular cleaning and maintenance, can make the machine core recovery factory, keeping the original flexible lubrication and tight.
11. K gold is represent?
A: K gold on behalf of the king's composition, generally do table K gold points, 18 K gold and 14 K gold. According to 18 k gold composition of seventy-five percent, twenty-five percent for other metals. The composition of 14 k gold is fifty-five percent, forty-five percent of the other metals.
12. What is the material of watch can grind the renovation?
A: 18 k gold, 18 k red gold, all steel watchcase strap can be polished renovation
