Timekeeping Accuracy

Pocket WatchSometimes your watch will lose precious seconds over the course of the day.

How accurate is your watch?

There is a tiny wheel inside every watch that acts just the same as a pendulum on a grandfather clock. Every oscillation back and forth should take exactly one second. But if the wheel mechanism is off by a just a matter of a few degrees, the watch time-keeping accuracy of a watch will suffer.

The hallmark of a great watch is accuracy. A measure of accuracy is a measure of value and usefulness.

We can measure this inaccuracy of any watch, mechanical or quartz, to within 2-3 seconds per 24 hours.

Watch makers can even build the moon phases, the leap year cycle, and all kinds of other features into their watches.  These cycles can become faulty over time, but we can fix that.

Vibrograph B600

B600The Vibrobraph B600 is a precision device that measures the amount of degrees that your timekeeping device is out of alignment. This device can measure the loss of even 2-3 seconds per 24 hours. On the display, the machine shows how many seconds that the watch loses over a day, as well as the amount of degress that it oscillates back and forth.  The oscillation should be as close to 360 degrees as possible.  The B600 tests the accuracy of mechanical watches.

Vibrograph B200

B200Another device used for the same purpose, the Vibrograph B200 measures that same things as the B600, but makes a print-out of the results. Tests how well your watch keeps time. This machine catches 1-10 seconds every 24 hours.  It takes the same measurement as the B600, only it prints the results on paper. This device also tests the accuracy of mechanical watches.

Quartz Watch Testing

quartzOur Quartz watch tester does the same thing as the other devices and more. Quartz watches run on batteries, and these batteries run out over time. Our equipment can test the time-keeping accuracy of your quartz watch as well as the remaining battery power. Our device measures different circuit currents flowing through your watch. By doing this, we not only test the remaining strength of the battery in the watch, but we can also determine if there are faulty circuits inside of the watch.
