Some people may feel strange, how can watch hands hurt the dial?
Yes, that can happen.
(1) watch pointer off: when the watch is violently shaken, the pointer may fall off, especially the second hand is more likely.
If the second hand (including a small second hand or other functional pointer) has fallen down, may be stuck between the time, minute hand and dial, then the watch to continue to move, the second hand will be moved and scratch the dial surface, resulting in dial scratches.
Of course, if you want to dial the needle at this time, the situation is even worse. You know, the value of the dial is very high, and some accessories are not easy to find.
(2) the gap between the hour hand and the dial becomes smaller: the distance between the hour hand and the dial is closest, if there is no safe gap, it will rub against the disc, causing arc scratches to the dial, which also includes the hour hand above the night, and the night powder will be rubbed off.
In addition, there is the hour hand position is too low, rub against the LOGO logo dial, the minute hand position is too low or the axle is skewed, resulting in the front end of the minute hand rub against the dial.
This will not only cause scratches, but also bring trouble to the watch.
(3) blue steel needle rust: blue steel needle although high-grade and beautiful, but it is easy to rust after dampness, when rust down “growth” out, will rub against the dial, resulting in circular scratches to the dial (see photos).
This rust mark in the repair, it is also very difficult to wipe off, rust composition should be called “iron trioxide”, in ancient times, the ancient people in the cave and rock wall above the painting is to use it to do pigments, can be preserved for ten thousand years.
(4) night light pointer on the dial also can not be ignored: especially the old watch, because at that time the night light materials are about Promethium, promethium is radioactive elements, is not very good for human health;
Now all the watches are made of Tritium, and tritium is safe.
Long-term use of watches, such as collectibles, need to pay special attention to, if the time, the minute hand is always fixed in a position, then the pointer above the night is harmful to the dial.
If promethium is used as a night light, it is possible to discolor the dial, mainly silver ray dial, while other types or colors may not. The discoloration position is exactly corresponding to the position of the pointer.
In my collection of watches, there have been 4-5 only appeared this problem, lesson painful ah.
If found that the watch pointer shift or fall off, it must immediately stop the watch, no stop second device, it is also necessary to pull out the table, let the watch gradually stop, at this time do not go to dial the needle and winding!
You can put the watch glass down, and then timely to the watch shop to do maintenance.
If the watch is severely shaken, also want to carefully observe the pointer, especially if the distance between the hour hand and the dial has no change, found in the blue steel pointer rust, should also be timely to do repair.
Belong TO COLLECT KIND OF WATCH, HAD BETTER BE EVERY OTHER half a year, PICK a needle afRESH, GO UP WIND.
