How to buy a high-quality mechanical watch, we need to know how to identify the quality of the mechanical watch good or bad, (goodluckwatch.com) for everyone to popularize some common sense

   The main considerations for purchasing a mechanical watch are still not separated from the three intricate factors of "styling", "brand" and "quality". Despite the growing acceptance of mechanical watches by consumers, there is no doubt that good styling and quality are still the basic principles for most consumers when buying a mechanical watch!

    (1) Types of Mechanical Watches

    There are various types of mechanical watches, including ordinary watches, calendar watches and automatic watches as well as mechanical calendar automatic watches, all of which add a set of calendar devices or automatic devices to mechanical watches. There are single-calendar watches on the market that present only the date, as well as double-calendar and full-calendar watches that present a weekly or even a monthly calendar.

The automatic watch is driven by the arm movement to drive the automatic hammer of the watch machine, so that the automatic device activities to tighten the winding, in order to drive the time. Automatic watch also has full-automatic and semi-automatic points, full-automatic is the table to any direction of movement can be wound up, semi-automatic only do single-direction movement can be wound up.

   (2) The number of diamonds in mechanical watches

    Most of the dials are engraved with the number of diamonds (e.g. 21ZUAN) and frequency (e.g. 21600) of the watch, the number of diamonds is related to the design and function of the movement, and the number of diamonds is only an index of the movement, which is related to the complexity of the movement, but has nothing to do with the accuracy of the movement's timekeeping. According to the function of the table, ordinary mechanical watches require 17--19 diamonds, automatic watches require 25---30 diamonds, and too many diamonds have little effect on the performance of the table, and generally only play a decorative role.

   However, the higher the frequency of the watch, the better, its frequency refers to the number of times the balance wheel swings per hour, the frequency of 18,000 times below the low-frequency table (slow swing), 21,600 times above the high-frequency table (fast pendulum table), the higher the frequency, the resistance to various forms of external interference, changes, the impact of the ability to be strong, and therefore go to the stability of the time is good and the accuracy of the high.
   (3) Mechanical watch exterior materials
     Nowadays, the majority of mechanical watches are made of all-steel, semi-steel and alloy. These three appearance materials refer to the different metal materials of the watch case and cover, semi-steel and alloy manufacturing cost is lower, the better watches are all-steel. All-steel watch refers to the case and cover are made of stainless steel; semi-steel watch whose case is copper chrome-plated, the back cover is only stainless steel; alloy watch case and cover of the main components are more than two kinds of metal or metal and non-metallic combination of substances with metal characteristics. All three have nothing to do with the quality of the movement. In terms of use, semi-steel watches and alloy watches are less durable and prone to wear and tear.
   (4) Grades of mechanical watches

   High-grade mechanical watches. It adopts bimetallic open balance wheel, or alloy material to make balance wheel; the balance wheel includes more than 16 screws and more than 17 diamond elements; it adopts double-layer hairspring, and the temperature coefficient of its material is very small; it has the performance of waterproof, shockproof and antimagnetic; the error of timekeeping is between plus or minus 30 and 45s in one day and one night; and the service life reaches more than 30 years under normal conditions.
   Mid-range mechanical watches. Adopting alloy balance wheel, including more than 10 screws and 15 diamond elements on the balance wheel; adopting flat balance spring; with anti-shock and anti-magnetic properties; with a day and night time error of plus or minus 45-60s; under normal circumstances, the service life of the watch is more than 15 years.
    Low-grade mechanical watches. Adopting copper alloy as balance wheel; no screws; diamond elements below 7 (some have no diamonds); no "three-proof"; one day and night time error of plus or minus 80s; under normal circumstances, the service life is more than 2 years.
    According to the above principles, check one by one, meet the requirements is a good watch, on the contrary, you have to consider whether it is worth spending so much money. Of course, each watch, each style, and there will be corresponding advantages and disadvantages, as long as you like it. goodluckwatch on the watch are carefully crafted, quality assurance, but also affordable, so that you have more style and confidence!
