As the saying goes, "Poor car, rich watch." A good watch is not only a symbol of status, but also the crystallization of human industrial wisdom. Many friends have the habit of collecting watches, but how to distinguish the value of watches is rare. So, how do we judge whether a watch is worthwhile in our daily life?
The Swiss Chronometer is certified as C.O.S.C., which is the most common type of hallmark we talk about today. But just because it's ****ing the same doesn't mean it's ****ing the same. To obtain this certification mark watches must be subjected to temperature, direction and speed tests for 16 days and 24 hours without interruption, which can be extremely demanding. The pros and cons of grinding determine the aesthetics of the watch and even its quality to a large extent.
Sanding includes functional sanding and decorative sanding... Functional grinding is mainly aimed at the operational efficiency of the movement, such as burr removal, contact surface matching, axle grinding and so on. While decorative is more inclined to aesthetic presentation, such as Geneva particles, pearl particles, fish scale particles, drawing, polishing, grinding, radial particles, chamfering, and so on. Decorative luster usually meets functional needs. Macro degree, working where the naked eye cannot see, fineness, degree of finish... Micro degree, chamfer flatness, gloss, and fineness and uniformity of particles are all considered criteria for motion grinding... The degree of refinement of the grind, the quality of the plating process and assembly, the treatment of defects, etc., all determine the quality of the grind... As a rule, the higher the degree of manual involvement, the better the finish... Of course, we should also pay attention to the craftsmanship of the artisan. In grinding, the most noticeable depth is probably the chamfer.
Plywood, tooth grooves, jeweled countersinks, screw grooves, etc... Chamfers cover almost any area that needs to be polished. The more chamfering is done, the more it will show the movement of gloss and the interplay of light and dark textures... But chamfers that are truly the best are few and far between... Watches always strive for perfection in the process, excellent movement not only travel accurate, but also beautiful enough, regardless of whether the back of the table is transparent or not, the watch, especially advanced watchmaking will spend some time in the movement polishing, and will be regarded as an indispensable process in the process of the indicator.
