How to accurately rotate the pilot watch circular flight slide rule

The accurate rotation of the pilot watch's circular flight slide rule is a key step to ensure the accuracy of the calculation. Here are some ways to ensure accurate rotation of a circular flight slide:


used luxury watchFirst of all, it is necessary to fully understand the structure of the circular flight slide ruler, including the active ruler (usually located on the bezel) and the fixed ruler (located on the edge of the dial). The scale numbers of the two sliding rules are opposite, and various calculations can be carried out by rotating the active rule so that the scales of the two sliding rules correspond to each other.


Before you perform a rotation, you need to know your computational needs, such as whether to multiply, divide, or convert units. Different calculation requirements correspond to different rotation modes and calibration points.


Find a reference point: First, find a reference point on the fixed ruler, which is usually a specific mark or number on the dial, such as 10. This reference point will be used as a reference for rotating the adjustable scale. Gently rotate the adjustable scale on the bezel until the desired calculation is aligned with the reference point on the fixed scale. This process requires care and patience to ensure that the calibration is correct.

Verify scale alignment: During the rotation process, constantly verify that the scales on the movable ruler and the fixed ruler are perfectly aligned. If there is any deviation, it may lead to inaccurate calculation results.


Since the scale of the circular flight slide is usually dense and the digital direction is opposite, it is necessary to pay attention to the scale proportion when rotating. Especially when the calculation involves large numbers, it is necessary to understand the relationship between the scale proportions on the movable scale and the fixed scale in order to correctly read the calculation results.


After rotating the slide rule for calculation, it is recommended to check the calculation result several times to ensure accuracy. It can be verified by other calculation tools or methods to ensure that the use of the circular flight slide is correct.


Avoid excessive rotation: When rotating the ruler, avoid excessive force or excessive rotation, so as not to damage the bezel or affect the accuracy of the slide ruler.


Keep the surface clean: Clean the surface of the pilot's watch and the slide rule part regularly to remove dust and dirt and ensure smooth rotation of the slide rule.


Follow the instructions: Different brands and models of pilot watches may vary in slide design, so it is best to read the instructions before use or consult the brand for proper use.


Through the above steps and methods, the accurate rotation of the pilot watch circular flight slide rule and the accuracy of the calculation results can be ensured.

What is the difference between jade and chalcedony in value evaluation

Image
There are significant differences between Qingshui jade and chalcedony in value evaluation, mainly reflected in the following aspects: Women's jewelry As a gem of jadeite, Qingshui jade is highly respected for its unique color and texture. Its output is relatively small, and high-quality Qingshui jade is a scarce resource. In the market, Qingshui jade has a high market recognition, especially high-quality Qingshui jade, is often regarded as the best collection and investment. Chalcedony is also a kind of gem, but its output is relatively large, and the market supply is more adequate. The market recognition of chalcedony may be slightly lower than that of aqua jadeite, especially in the high-end jewelry market. The color of green jade is clear as water and bright green. The brighter and more uniform the color, the higher its value. Its appearance is shiny and bright, with glass luster, which can reflect light well and show the brilliance of gems. Although the color of chalcedony is...

How to judge the clarity of a diamond by fire color

Image
It is limited to judge the clarity of the diamond directly through the fire color, because the fire color is mainly the comprehensive performance of the diamond cutting, the refraction and reflection of the light inside the diamond, and the clarity refers to the number and size of the internal and external defects of the diamond. However, the strength of the fire color can indirectly reflect some information about the clarity of the diamond, but it needs to be considered in combination with other factors. Second-hand jewelry Diamonds with high clarity (such as FL, IF grades) have few internal defects, light spreads more smoothly inside the diamond, and the reflection and refraction effect are better, which may show a more intense fire color. Diamonds with lower clarity have more internal flaws, which will hinder the propagation of light and cause the fire color to weaken. Especially when the flaw is located in the key parts of the diamond (such as the countertop, crown main facet, etc....

Gold bracelet scratches How to choose the right toothpaste

Image
When choosing the right toothpaste, you need to pay attention to the following aspects: Find beautiful earrings, necklaces & bracelets Type of toothpaste preferred Non-abrasive toothpaste is preferred because abrasive toothpaste may contain tiny particles that may cause further scratches or wear on the surface of the gold bracelet during the wiping process.Choose toothpastes with mild ingredients and avoid toothpastes that contain bleach, special chemicals, or strong cleaners, which may have adverse effects on gold bracelets. Choose toothpaste brands that are well known in the market, which usually undergo strict quality control, have relatively safe ingredients, and have less potential damage to gold bracelets. Refer to other consumer reviews and feedback to understand the effects of toothpaste in actual use and possible problems. Squeeze out the appropriate amount of toothpaste, not too much, so as not to waste and create unnecessary foam during the wiping process. Use a soft clo...
