Especially for men who often need to watch time with their watches, they should choose a clear and easy-to-see watch with a clear and intuitive scale to understand the time at a critical moment. You can't choose complicated and difficult scales because of the good style, it will give you more difficulty in reading, and the practicality is not high. That is the choice of dial size. To choose the dial size according to the thickness of your wrist, this will be more lining yourself. If you wear a water meter that doesn't match the size of your wrist, it's as awkward as wearing someone else's watch. Need to be considered. In daily life, it is inevitable that some daily splashing will occur. If a watch has a high value, but it is expensive and cannot touch water, then the probability of accidents is great and the service life will be short. This result should not be what you want! So the player table should be selected with a certain waterproof function!
Manual winding movement, the earliest movement spring spring must pass "human intervention", the wearer should manually rotate the clockwork on the crown to walk normally, usually the last spring 24 hours, manually The chain movement was also the earliest machine, and its ancestors appeared on pocket watches as early as the 15th century. It is now also used by some high-end brands, but more wearers will forget to “wind up” and “stop” their time. The self-winding movement is wound by the movement of the watch. Through a swinging oscillating movement, the spring of the watch is slowly tightened, and the watch realizes the effect of “self-running”. The self-winding movement is now the choice of most mechanical watches. As long as it is worn every day, there is no need to wind up, and the hairspring that is evenly stretched with the movement is more conducive to the accuracy of travel time. When it comes to quartz movements, we must first mention the "quartz crisis" of the 1970s and 1980s. It was its birth that shocked the entire Swiss watch industry, which caused many European mechanical watch factories to declare bankruptcy and end early. His own watchmaking career, precisely because of its existence, ignited the birth of the "Swatch" watch, it can be said that a generation is stronger than a generation. fake breitling navitimer watches
"25 JEWELS" on the movement is commonly known as "25 drill"In 1704, natural diamonds were first used in watch movements and patented. Natural diamonds are used as bearings, which greatly improve the transmission efficiency of the gears, greatly improve the travel time accuracy of the watches, and greatly extend the service life.The use of diamonds for watches was technically secret at the time, and many watch manufacturers began to follow suit, but the selection, punching, and installation were very difficult and costly.
In 1892, the French invented synthetic diamonds, whose main component is aluminum oxide, which is sintered at high temperatures. Various colors such as red, blue and white are added with different colorants. When using chromium oxide as a coloring agent, it is a red diamond that is common in watch movements, also known as artificial ruby. Automatic mechanical movementRefers to a watch that uses a barrel to store power. The beginning of all the power from the spring to send the power to the second two cars, three cars, four cars, five cars (escape wheel), clips to the balance wheel, and then the balance of the reaction force to the horse, so that The location where it was restored before, so that the entire operation process can be repeated and continue to generate power. Mechanical watches can be divided into two types: hand chain and automatic winding. A. Hand movement:By turning the faucet by hand, the winding system is driven to drive the spring on the chain.B. Automatic movement:The automatic disk is oscillated back and forth by the swing of the arm to achieve the effect of automatically tightening the spring.
