Quartz Watches That Lose Four Seconds a Day249

Quartz watches are known for their accuracy, but even the best quartz watches can lose a few seconds per day. This is because the quartz crystal in the watch is not perfect and can vibrate at a slightly different frequency than the desired frequency. As a result, the watch will lose or gain a few seconds over time.

The amount of time that a quartz watch loses or gains per day is called its "drift rate." The drift rate is typically expressed in seconds per day (spd). A watch with a drift rate of -4 spd will lose four seconds per day, while a watch with a drift rate of +4 spd will gain four seconds per day.

The drift rate of a quartz watch can be affected by a number of factors, including the temperature, the humidity, and the age of the watch. Temperature changes can cause the quartz crystal to vibrate at a different frequency, which can lead to a change in the drift rate. Humidity can also affect the drift rate, as moisture can get into the watch and cause the quartz crystal to corrode. The age of the watch can also affect the drift rate, as the quartz crystal can become less accurate over time.

Most quartz watches have a drift rate of between -10 spd and +10 spd. This means that the watch will lose or gain no more than 10 seconds per day. However, some quartz watches have a drift rate of less than 1 spd. These watches are called "high-accuracy quartz watches" and are typically more expensive than standard quartz watches.

If you are concerned about the accuracy of your quartz watch, you can have it calibrated by a watchmaker. Calibration involves adjusting the watch's movement to ensure that it is running at the correct frequency. Calibration can typically be performed for a fee of around $50.

Here are some tips for choosing a quartz watch with a low drift rate:
Look for a watch with a drift rate of less than 10 spd.
Choose a watch from a reputable brand.
Avoid watches that have been exposed to extreme temperatures or humidity.
Have your watch calibrated regularly by a watchmaker.
