In general, custom watches take between 25-60 days. The exact time is determined according to the material, style and quantity of the watch.
Overview
The mechanical watch movement has a resonator consisting of a balance wheel and a balance spring. The stability of the oscillation period determines the timing accuracy of the watch. The oscillation of the balance wheel is swinging left and right, and its swing amplitude is the swing amplitude. The swing amplitude is also called amplitude in the watch industry. According to the definition of physics, the amplitude is the maximum displacement of the oscillating object from the static equilibrium position.
The swing of the watch is always changing, and its stability and size depend on many factors. The most important thing is to determine the degree of tightness of the clockwork. The more full the spring is, the higher the swing. In addition, it is also related to the friction of the shaft of the balance wheel. When the position changes, the gravity direction of the balance spring and the frictional condition of the balance of the balance wheel also change. For example, when the watch is in the plane and vertical, the swing is very obvious, and the fa?ade is usually about 40 degrees lower than the plane swing.
There are many other factors that affect the swing, such as the design of the watch, the lubrication condition, the axial and radial clearance of the gear, the smoothness of the output of the spring torque, and so on.
The swing of the watch is not as high as possible, because the rotation of the balance is not possible to reach 340 degrees. If the swing is too high, it will cause the watch to “clip down”. This is actually a phenomenon that the balance wheel pin hits the outside of the fork of the pallet fork, which makes the watch change very fast, and it sounds like the watch is moving. The sound loses its normal rhythm and becomes like the hoof of the hoof. It is generally believed that the watch is suitable for a swing between 240 and 320 degrees in the state of a full-chord plane.
measuring
The swing difference: the watch measures two planes (face and face) and three vertical planes (down, left, and up) in two states after full line and real 24 hours. The swing of the five positions changes, and the maximum difference is taken as the swing difference compared with the same position. The swing of the swing is also an important indicator of the performance of the watch. It also reflects the quality of the starting strip and the hairspring and its design and assembly. Usually, the drop is below 50 degrees.
The swing is flat: the watch measures two planes (face and face) and three vertical faces (down, left, and up) in the full string state. Change, the maximum difference is taken as the swing level difference compared to the plane position on the face of the watch and several vertical positions. The swing level difference is also an important indicator of the position error performance of the watch, usually requiring a flat difference of less than 50 degrees.
The minimum swing of the 24-hour fa?ade: after the watch has been running for 24 hours, the minimum swing of the vertical plane (usually the left position) cannot be lower than 180 degrees. The watch has better performance at high swings than at low swings, especially for watches with calendar attachments. The minimum swing requirement for a 24-hour fa?ade is especially important.
The measurement of the swing of the watch is generally measured by an amplitude meter. In the early years of Switzerland, models such as AM201 and GD-50 were produced. It is measured by the so-called "base angle method", so it is necessary to select the corresponding angle of the balance of the watch to be tested before measuring. In the use of instrumentation to detect watches, a complete detection unit requires a meter and an amplitude meter. In the previous watch repairs, I only saw the meter, and the amplitude meter was only visible in the watch factory. Explain that everyone generally only pays attention to the speed and accuracy of the watch, and the swing and precision are equally important and interrelated. The technical indicators of the swing are not good, and the watches with too large a gap and a big difference must not go well. Especially when calibrating the balance of the balance and adjusting the position error, it is necessary to refer to the swing. The concept of the swing requires the maintenance technician to have a higher level of watch theory.
Once the balance and the pallet of the watch are removed, the drive train will be unobstructed and the high-speed rotation will occur. This is called “running string”. Because the wheels are all driving wheels, the axles are driven, so several gear pairs are superimposed. To the last stage escape wheel, the running speed is extremely high, especially when the spring is nearly full. The sound of squeaking, long-time high-speed running strings can also cause rapid wear on the shaft of the gear.
Running strings are also divided into two situations:
1. Pure movement state;
2. The movement has been fitted with a needle and assembled into the case.
The second state is more important, because many watches are only loaded into the case, and the problem occurs when the back cover is closed. The typical reason is that the movement of the movement is not the same as the handle of the case, but also organic. The core is subjected to some pressure, causing the splint to be pressed and the part gap to be lost.
The main purpose of the running string in the assembly and repair of the watch is to check whether the axle is reliably entering the shaft, the gear alignment and meshing state, the lubrication of the shaft eye, the beating of the gear end face, the radial clearance of the gear shaft, the axle wheel The concentricity of the tip, the sensitivity of the wheel train, etc., can all be observed in a short time by running the string. In particular, pay attention to whether the wheel train has periodic block, speed change, sudden and slow rotation or even stuttering. According to the gear ratio of the gear or their respective rotation cycles, the position where the problem may occur is judged. Where, this is the purpose of doing the string.
The gear train on the dial mounting surface also includes the relevant gears with additional indicating functions such as calendar and day calendar. Their speeds are relatively slow. It is also possible to check whether the working state is reliable by running the strings. The running string should be performed under the weak torque of the spring, and all the added oil should be filled.
In addition, the assembly problems can also be checked by running the strings, especially the gap between the hands, the gap between the hands and the dial or other marks, the gap between the second hand and the watch glass, and the like.
What are the maintenance and daily use of world famous watches? Watches are becoming more and more popular in today's society. In addition to watching time, more people regard it as an ornament. Most people like to choose the famous watch brand, but for the wrist. The maintenance of the watch is still indispensable.
Waterproofness of the watch
The waterproof of the watch relies on the waterproof ring of the mirror, the back cover and the head to reach the corresponding standard.
The aging of the waterproof rubber ring will affect the waterproof performance of the watch, so the waterproof rubber ring and the head (including the waterproof ring) of the watch should be replaced regularly according to the use. The quartz watch must be replaced with a waterproof component at the same time to change the battery to ensure good waterproof performance.
Any waterproof watch should not be worn in hot water baths, saunas or in environments with widely varying temperatures. Because the waterproof rubber ring is affected by temperature, it will expand and shrink, and the gap will accelerate and aging, causing water condensation in the water inlet and the surface, which will seriously damage the machine.
Please clean the strap and case regularly. It is recommended to go to the professional watch cleaning and maintenance station for maintenance. Even for watches with high water resistance, the watch should not be placed in the water for a long time and washed by soaking.
The watch must not be subjected to severe impact or falling. Do not touch the watch to the surface of the same or higher hardness, such as oxidized metal, quartz crystal, grindstone, sandpaper, granite surface, concrete wall surface, etc. When the watch is taken off, it is a habit to put it in a safe place.
Watch renovation
After the watch has been marked with a lot of lines, you can drop one or two drops of water on the surface of the watch, and then squeeze a little bit of toothpaste to remove the scratches and make the watch look like new.
Because the watch is often worn, but the leather strap is dirty, how can I clean it? To this end, Baojue Technology will introduce some methods of maintenance and cleaning today, hoping to help everyone.
Common belts are available in a wide range of materials, such as crocodile skin, lizard skin, ostrich skin, shark skin and calfskin. No matter which material is worn for a long time, it will produce odor. Therefore, it is true that the belt is not cleaned and kept dry. The second method.
If the strap is wet, wipe it off with a cloth immediately. If there is dust, it should be clothed (if it is a damp cloth, it should be wiped dry after cleaning). In addition, if it is exposed to the sun for a long time, it will cause deterioration of the strap, which is also a place to pay attention to.
Brush a little soapy water, quickly wash the dirt, and wipe with a slightly damp cloth. To prevent soapy water from penetrating into the cortex, the whole process is best done in 20 seconds. In addition, consumers can also apply some leather oil on the strap. The leather oil has a protective effect on the watch, which can make the maintenance work more complete.
The strap is worn for a long time, and in addition to the odor, "hardening" is a common symptom. If the strap is often in a humid environment, it will accelerate its hardening speed. The sweat will also erode the cortex, causing the strap to deform, harden or even break, inexplicably causing the watch to be lost or broken. Therefore, in addition to the usual maintenance, it is absolutely necessary to not bend it when the strap is hardened, and to change the strap at the right time.
For every two or three months of wearing a leather strap, use a detergent to wipe and maintain. How to look at the surface of the belt from the surface is good or bad: better straps, generally both edges are sewn with a thread, some of the low-grade are basically glued, the strap will be easy to open after the water. The strap that is cracked and opened should be replaced in time.
1. Wearing A Watch Steaming Sauna, Completely Wrong Behavior
Because No Matter How Many Meters Of Water-Resistant Depth, You Can Not Steam Sauna, There Will Be No Problem In Appearance In A Short Time, In Fact, The Movement Has Been Infringed. Because The Appearance Of The Watch Is Composed Of Materials With Different Expansion Coefficients, If The Wearing Environment Temperature Of The Folding Watch Is Greater Than Or Equal To 50 Degrees, A Pressure Difference Will Occur In The Watch. Under The Action Of Air Pressure, The Air In The Watch Will Run Outward. When The Temperature Difference Is Restored, The Outside Air Runs Back Into The Watch. The Temperature In The Steam Bath Is Much Higher Than The Standard. The Air In The Watch Will Run Out When The Humidity Is Higher Than The Standard Air. In Some Cases, The Water Does Not Appear In The Watch Immediately, But The Temperature In The Watch Is Higher When The Temperature Is Low. The Standard Air Will Condense On The Glass, Forming Water Droplets Or Fog, And The Heat Of The Steam Will Accelerate The Aging Of The Waterproof Apron And Will Not Protect The Movement Normally.
2. It Is Unscientific To Use The Condensation Of Water Droplets To Confirm That The Crystal Is Sapphire Crystal, Because Some Mineral Glass Will Also Make The Water Droplets Condense, And Some Water Droplets On The Sapphire Crystal Will Spread, But The Degree Of Abrasion Resistance Is The Same. The Material Manufacturer Will Explain It, Do Not Use Water Droplets To Try.
3. After Changing The Battery, The Quartz Watch Is No Longer Waterproof. It Is Not Accurate When You Go. The Professional Maintenance Equipment Is Very Perfect. After You Change The Battery, You Will Use Professional Equipment To Re-Press And Re-Set The Waterproof With Professional Equipment. Measure Whether The Travel Time Error Is Within The Normal Value. So Please Be Sure To Change The Battery In Our Cassie.
The Maintenance Of The Watch Should Be Regarded As A Learning. People Who Are Interested In Watch Oils Want To Know How Long It Takes For The Watch To Be Cleaned And Cleaned. It Is Said That In General, 1-3 Years Must Give A Full Maintenance To The Beloved Mechanical Watch, Followed By Real-Time Appearance Maintenance. . However, The Point Here Is That The Maintenance Of The Watch Can Be Reasonably Arranged According To The Actual Situation Of Use.
Watches Are Available In Our Daily Life In Two Forms, One Is Always Worn, And The Other Is Not Worn. If It Is Said That The Watch Does Not Leave The Hand 365 Days A Year, And It Still Maintains All Normal Functions During Use, Then This Watch Can Be Maintained Once Every 3-5 Years. This Is Due To The Long-Term Use, The Loss Of Lubricating Oil In The Watch Or It Is The Dry Operation That Affects The Normal Operation Of The Movement. The Outside Dust Enters The Watch And Causes The Movement Of The Movement To Accelerate. When The Use Finds A Large Error, Or There Is Abnormality Such As Water Inflow, It Needs Immediate Maintenance And Care.
If It Is Said That The Watch Is Not Worn For A Long Time, Then You Must Choose A Suitable Placement Position, 5-10 Years To Maintain It Once, But During The Period You Need To At Least Let The Movement Run Every Month, By The Way, Observe Whether The Watch Function Is Normal. The Operation Of The Machine Will Be Worn Out. It Is Best Not To Use The Linked List Box When Using The Watch Case For A Long Time. It Is Best To Stand Still. With A Suitable Maintenance Plan, The Life Of The Watch Will Increase A Lot, And It Will Be Guaranteed To Last For A Long Time, So That The Maximum Performance Of All Aspects Of The Watch Can Be Utilized. Therefore, The Maintenance Of The Watch Should Be Regarded As A Learning, And In The Renewal Of New Technology, The Maintenance Of The Watch Also Needs To Be New, Such As The Ceramic Watch Of The Current Trend Of Preface, The Specific Maintenance Of This Material Has To Be Studied Like Learning.
