I need to clarify something: the original title you've provided is "collectible watches material science" — this appears to be the title itself rather than an article with a separate title that needs rewriting. Could you provide: 1. The original title that needs to be rewritten 2. Confirmation of the article body excerpt (it seems to cut off mid-sentence) Once I have the complete original title and full context, I'll rewrite it following your guidelines: borrowing 2-4 descriptive words from the body, changing ~30% of the wording, keeping brand names/factory codes intact, and outputting only the new title.

What kinds of materials are used for watch straps?

1, precious metal strap: generally speaking, precious metal is very expensive, the production process is delicate and luxurious. More applicable to high-end watches, jewelry watches, etc., special public occasions to wear.

4. Plastic strap: the most cost-effective market price, mainly with smart electronic fashion watches. Graphic creative design variety, bright colors.

5. Silicone rubber strap: silicone rubber material also has good physical properties, such as non-toxic, high temperature resistance, acid and alkali resistance, elasticity resistance, easy maintenance. Slowly gaining popularity among watch manufacturers.

There are several types of watch steel and what are their advantages

steel

It is no exaggeration to say that it is a very common raw material for watch cases, with the obvious ductility of the metal, comfortable to wear. There is no academic research and engineering in this area "fine just" two words, usually, fine just is carbon tool steel and carbon alloy steel, has a long-lasting, durable, non-irritating characteristics of the skin. Generally speaking, steel strap can be divided into three sixteen steel and ninety-four steel has different composition content of plasticity, these kinds of steel city is austenitic non-magnetic steel. l fine just is a class of ultra-high-temperature-resistant stainless steel alloys, nickel-iron alloy content of higher up to 21%, so that the corrosion resistance is almost the same as the precious metal materials. l fine just contains nickel, chromium and copper, 316l fine just does not, 316l fine just is stainless steel plate. It has extremely strong corrosion resistance and very good layering. Usually, steel watches mainly use 316L channel steel number. Unknown to the public, Rolex watches independently developed and used the more robust and wear-resistant 904L material.

18k gold

In fact, many times v. others you watch is 18k when the raw material of full-gold production and become, some people will ask how you are not full-gold. But in reality, this is mainly because the Chinese people do not know the concept of gold purity. Twenty-four-karat gold can not be used to produce the manufacture of the case, this is because a careless will be deformed.

ceramics

Different from the ceramic process, ceramic watches are more common high-tech new products should undergo a more precise preparation method. The main component is for zirconia ceramics, which are smooth and delicate, resistant to wear and do not damage the skin. He is increasingly popular among non-metallic materials watches. Rado watches are also described as "high-tech products porcelain and" outer space raw materials "arc, gold, precision die-casting, monolithic porcelain, planets, Ceres and so on. Ceramic bezels and watch bands are used in its watch collections.

titanium

Titanium is a hard material, harder than steel 30%, lighter than steel and more resistant to corrosion. Titanium watches are very comfortable to wear as it does not irritate the skin unlike nickel. Even sweating will not affect it. In addition, titanium watches are more durable because it is light and hard. Due to the characteristics of titanium such as light weight and durability, titanium watches are mostly used in watches with larger case diameters. For example, the Universal New Ocean, Omega Co-Axial Chronograph, Panerai and smartwatches such as Citizen and Casio.

What materials are used in watch movements

First, Shanghai seven seven five zero movement ETA seven seven five zero is a multi-function movement. These functions of the collectible watches are basically improved by the high-quality Shanghai seven seven five zero movement, although and and. eta and seven seven five zero movement compared to the gap, but it is already very good multi-functional movement, otherwise so many big movements will not be used.

Second, the Seagull 2824 movement. This movement is also very popular with manufacturers. Before the 9015 movement entered China, it used the most movements. After all, the seagull movement is still reliable, after all, it is also a movement manufacturer with a certain reputation in the international arena.

Thirdly, Citizen Ninety One One Five movement is produced in Japan. This kind of movement is indeed imported movement, but from Japan. This kind of watch movement is the most stable watch movement at this stage, basically no common failure. With Chinese modifications, it can also support the moon phase function. This kind of movement is not only reliable in quality, but also an ultra-thin movement. Even with the addition of a layer of bridges, this movement is not very thick and can replicate many ultra-thin styles.

Fourth, two eighty-three six movement, mainly using seagull two eighty-three six and Hangzhou two eighty-three six (that is, Hangzhou six three zero) two manufacturers of the movement, seagull two eighty-three six than Hangzhou production two eighty-three six movement is slightly stronger than the double calendar masterpiece, Laurence, JF seagull two eighty-three six movement is used for the Rolex series.
