Want to play the clock, learn this
What is mechanical clock, how is the clock quatrz? How to read the parameters of a watch? This is the article you need to read.
Basic knowledge of watches you should know
The watches today are not only to see the time, it is also a jewelry for both factions, the most symbolic character for the personality and value of the wearer. However, most of us still have only one very basic definition as follows: "The clock is a wrist watch to see the time" , but do not know what kind they have, read the parameters. How basic? This article will give you the most basic knowledge and also the most important to really understand what is the clock.
1. Classification
Modern watches have 3 types of Mechanical Watches, Quartz Watches, Citizen's Eco-Drive and smart watch.
The clock uses Eco-Drive technology, does not use batteries, runs entirely on energy generated from any light source, from sunlight or natural, artificial light.
Mechanical watch is a clock that uses a winding machine, without electronic devices. Watches are usually made of glass like 17, 21, 25.
There are two types of mechanical watches , one is handwinding and the other is automatic (Automatic) - using the wrist wrist movement to maintain energy.
Operation of a Seiko mechanical watch.
Quartz watches are a type of watch that is powered by a magnetic impulse through a battery power source. For example, the G-Shock and Edifice watches of Casio are all Quartz watches.
To distinguish what is a running clock, a Quartz watch has a detail that looks at the second hand. Mechanical watches always have smooth second hand needles, while Quartz watches are mostly runners . For ease of understanding, you can see the following picture:
On the left is the muscle, on the right is Quartz.
Smart watch : Currently there is no most accurate definition of this type of watch, but it can be understood that it is a battery-powered watch, in addition to the function, it is also equipped with more features. Other auxiliary features such as displaying messages, calls, connecting to smartphones or simply monitoring health.
For example: Apple Watch.
2. The basic specifications of a watch
Here the writer only offers the most basic knowledge, not heavy technical to anyone can understand through a reading but still ensure sufficient criteria for readers to understand about 1 clock.
Speaking of watches, the most important is the movement, which is the most valuable component in a watch. Currently popular, Swiss machines are the most advanced (Swiss Movement; Swiss Quartz), most commonly the Japan Movement (Japan Quartz) and the cheap China China.
For example: The Automatic Seiko SKX009 mechanical watch uses 7s26s with 21 glasses (21 Jewels), the higher the number of glasses, the better the device.
The most interesting parameters when watching a watch:
First it is the size, there are 2 popular ways to record, 1 is to measure according to the surface diameter (with knob or no knob) - case diameter (with crown) | (Without crown).
There is a formula to select the appropriate clock size as follows, use it for reference:
- Wrist circumference / 4.5 = optimal clock size.
- Wrist circumference / 4 = maximum clock size.
- Wrist circumference / 5 minimum watch sizes.
To know if a watch is too big for the hand, we need to see the Lug to Lug parameter, if this parameter exceeds the wrist's wrist length, it will be very bad to wear it.
Lug Width : This is the parameter that we need to know to know how much the watch uses the size of the strap, usually with the common dimensions of 16mm, 18mm, 20mm, 22mm, 24mm, .
Material constitutes:
- Watch glasses:
- Mineral glass (Mineral glass): Ability to resist light scratches.
- Hard glass: Hard scratch resistance.
- Sapphire glass (Sapphire): Good scratch resistance.
- Sapphire glass (Sapphire glass, Sapphire crystal): Scratch-resistant almost perfect, often equipped with high-end watches.
It is not necessary to buy Sapphire glass because the watches equipped with sapphire glass usually cost much higher. The hardened glass is popularly capable of scratching in everyday activities very well, and if scratched too much, it can be re-polished.
- Watch case:
- Base metal is a cover made from ordinary steel, or copper, or Antimol for plating. This type after 1 - 3 years will peel. For identification, see if the bottom has Stainless Steel Back or Base Metal recorded.
- Stainless steel or stainless steel casing: This is the most popular material with current watches, the advantage of this type is durable, cheap production costs. Identify by the words Stainless Steel or All Steel .
- Other types of shells: Carbon casing, ceramic, Aluminum or even titanium only appear on super high-end watches to add value to the watch.
- Strap:
Types of popular watch cords today:
- Stainless steel wire or stainless steel (Stainless Steel): Durable, not oxidized or rusty.
- Plating wire: A type of wire made of ordinary steel or copper, plated with ball. This type of wire will oxidize over time.
- Titanium alloy wire: Light, durable, no oxidation.
- Leather band (Leather Band): There are many types, made from different types of leather (for example, ostrich leather straps, daisies, crocodiles, .).
- Plastic wire, cloth wire, rubber wire: This type is used quite extensively, from cheap watches to the most advanced ones.
