![]() If you’re after a precision watch, this is not an ideal situation for you. The opposite is in fact true: This is not a precise watch and is merely a matter of having been lucky and having looked at the watch at the right moment. After five days, the watch would appear to be synchronised exactly to the time standard, and you may feel like you have an accurate watch. The next day, it may be +8, then +10, then -5, then -7, then +4. Its daily rate variation on one day may be -10 seconds. If you have a watch with a stable rate, then you can call it a precision watch. Essentially, it does not tell us whether the time is accurate or not, rather if it consistent. Rate stability, tell us how a timekeeping device can produce time with the same accuracy over a certain time interval. If a watch is synchronised exactly with Coordinated Universal Time (UTC), which is the reference point for other timezones, and is 1.3 seconds fast a day later, then the watch is accurate to within 1.3 seconds per day. We measure the performance of a timekeeping device based on two factors: Firstly, it’s accuracy, and then on rate stability. On the contrary, they both have completely different meanings. Often people say that a watch is precise or accurate and it is generally understood to mean the same thing. Hence, if your watch suddenly stopped in the middle of the day, check some possible reasons that might be causing the problem using this guide.But what is actually meant by the term "accuracy"? One of the first things to note is that "accuracy" and "precision" are not interchangeable. ![]() A watch can experience wear and tear, but if left unnoticed, it can further damage the rotor and cause permanent malfunction to the timepiece. At least, you can prevent dust build-up, which can eventually damage the rotor of the watch. To prevent this, make it a habit to have your watch checked and cleaned by a professional repairman. ![]() Dirt and dust blockages are most likely to happen if the watch hasn’t been serviced. Otherwise, over-winding it poses a risk to damage your timepiece.Įvery timepiece needs to have a maintenance check-up at least after the certain number of years. When winding a watch, it is always important not to overwind it to avoid damaging the rotor. This is associated with a defective winding mechanism, which could have something to do with the impact at the rotor. If this happens, the spring will break and may cause permanent damage to your watch if left unattended. An old timepiece’s tendency to reach its maximum tension is high. It is likely common to have 90% of the spring torn because the material is either exposed to natural aging factors or has too much clamping pressure.Īutomatic watches have their mechanism to prevent the rotor from over-tightening. The mainspring is an essential part of any timepiece. Your watch also tends to get loose screws if you are always playing rigorous sports such as golf. If you suspect that this maybe the case, seek help from an authorized watch repairman and have your timepiece checked. This is a common issue because even regular hand and wrist motion can cause a screw to get loose. The loosened screw is probably blocking the internal mechanism of the timepiece and it causes the movement to halt. Having a loose screw is one possible reason why your watch stopped functioning. However, if after the assessment, the watch still won’t work, then here are some reasons for the problem. On the other hand, if it is a quartz watch, then the problem may be the battery. In other words, assess the watch and try basic troubleshooting steps. You can gently swing it off and see if it will function again.Īlso, you can try winding the watch for a few times to check if it works again. If you think that your automatic watch stopped, check the timepiece first since it might just be experiencing a temporary halt due to inactivity.
