Wus watch timegrapher
The standard acceptable accuracy of mechanical wristwatches is as follows: This is generally not a problem unless the watch is constantly in extreme weather environments and is corrected by a very simple regulation. In modern watches most materials and designs are able to compensate for the changes and maintain a consistent rate. Temperature changes expand and contract many of the parts, changing the dimension and shapes - especially the balance wheel and hairspring. Temperature: The environment may have an impact on how accurate the watch operates.Watches are typically adjusted to between 2 - 8 positions:Ī watch adjust to 2 positions has been adjusted to the first 2 positions, a watch that has been adjusted to 4 positions has generally been adjusted to the above 4 positions and so on. If you remove the watch at night you may want to find the optimum position that will compensate for drift during wear. An adjusted watch should perform overall within the specification when worn throughout the day.
The balance wheel has been adjusted to compensate for losses and gains in different positions.
Position: Due to gravity a watch will gain or loose more time if laid to rest in a single position.
To put things in perspective, if a watch is only 99.9% accurate it would be off by 1 minute and 27 seconds per day, which is unacceptable in the luxury watch world.Īccuracy is dependant on a few variables, such as: In the world of mechanics, anything assembled of small parts which are capable of maintaining 99% accuracy would be considered a top-tiered piece of machinery.
