Cufflinks frequency the higher the better, its frequency is the number of ferry per hour swing, the frequency of 18,000 times less than for the low-frequency table (slow swing), 21 600 times more than the high-frequency table fast swing table the higher the frequency, the more accurate travel time. Variety of mechanical watches have a common table, calendar, and automatic table and mechanical calendar automatic watch, add a calendar device or automatic device on the basis of the mechanical watch. Su Mei said, now more and more professional women commence to wear cufflinks, let alone the men. And showed only a single calendar date; also showing double calendar and calendar week calendar and even calendar.
The automatic watch is the automatic hammer to rely on the arm movement to drive the printer, so that the automatic device active volume wound, thereby giving impetus to the travel time. Automatic watch is fully automatic and semi-automatic table movement can be to any direction winding, semi-automatic only a single direction in order to wind it. The latter has now been eliminated, not production, so the new automatic table are automatic table. No doubts that the cufflinks of the front-line brands are excellent in quality but expensive. The mechanical watches are divided into senior cufflinks, cufflinks Intermediate and low-level cufflinks three levels. These three levels is classified according to the mechanical cufflinks mechanical structure and performance characteristics.
Senior cufflinks. It to bimetallic opening balance wheel or alloy material balance wheel; screws on the balance wheel of not less than 16; more than 17 diamond components; double springs, the material very little temperature coefficient; with "three anti- (waterproof, shockproof, antimagnetic) performance; day and night travel time error is plus or minus 30 to 5LS; under normal conditions, the service life of more than 30 years. While a large part of the cufflinks on the market is prone to be poor imitations. Intermediate cufflinks. Alloy wheel, screw balance wheel, more than 10; more than 15 diamond components; flat springs; shockproof, antimagnetic devices; day and night travel time error of plus or minus 45 ~~ 60s, under normal circumstances, the useful life more than 15 years.
Low-level cufflinks. The copper alloy for the balance wheel; screws; diamond components in the following seven (some non-diamond); "three", a day and night travel time error of about plus or minus 80s, the useful life of more than 2 years. Check whether the automatic swing. The method is: stop and go relax winding table gently in his hand, and slowly on the bar while watching the second hand, second hand should be followed by rotation in the beginning of a winding, otherwise do not meet the standards. When traveling abroad, Su Mei in foreign markets caught the eye of the mens cufflinks. Check the sound of the table in a variety of locations. After the winding of the last few laps, the surface facing up, down, handle head-on, down, toward the left and to the right, listen in each position of the frequency of the beat should be basically the same on the full winding, the sound should be crisp without a murmur.
