When your Rolex is not functioning correctly, a simple test can give you an early indicator. The test measures time accuracy.

Reasons Why A Rolex Datejust Is Running Slow


Timepieces such as the Rolex Datejust watches are accurate. Plus or minus 2 seconds per day are the company standards. You should not lose or gain more than 2 seconds per day with a Rolex Datejust chronometer.

It is possible for a Rolex watch to be inaccurate for several reasons, including but not limited to:

A major impact has been suffered by the watch

Rolex Datejust movements can be damaged if the watch has been dropped or suffers a significant impact. Rolex Datejust watches do not have electronic quartz movements; they have mechanical movements with many moving parts:

  • Powering the watch is its mainspring
  • During a watch's operation, time is measured by the balance wheel and hairspring oscillations
  • Assigns oscillator pulses to the watch escapement
  • Power is transferred through the gear train
  • There is a dial train that moves the hands
  • And much more

To make the watch accurate, each component is positioned precisely on the calibre. Despite the robustness of Rolex's movement, it can be upset by a violent impact. When a watch moves inaccurately following an impact, it is an indication of damage to the watch movement.

The accuracy of your Rolex Datejust watch should be tested for 48 hours following an impact. As long as the time remains accurate, you can be confident that the impact did not affect the Rolex Datejust. A Rolex Datejust which lose more than two seconds every 24 hours are considered abnormal. How serious is this? In order to check whether the Rolex Datejust is damage, it should be taken to a Rolex Service Center.

Watch is Running Dry

As the Rolex Datejust watch has many moving parts, lubricants are required to maintain accuracy and control friction. Watchmakers refer to a watch's lubricant level as 'running dry' when it is too low.

The average Rolex lubricant lasts between five and ten years, but that is just a general rule of thumb. Because, the time limit starts from the moment the Rolex Datejust was purchased, or does it start with the day the watch was manufactured? What was the length of time between when the Rolex Datejust was manufactured and when you purchased it? A lot of things are unknown. Dont rely on the lubricant expect lifespan.

When Rolex Datejust watch run dry, the lubricants have evaporated. It is necessary to replenish lubricants when they are low. A qualified watchmaker performs the operation who knows exactly what type, where, and how much lubricant is needed.

The Rolex Datejust watch will lose a few seconds per day when the lubricant is low. When running properly, a Rolex Datejust watch shouldn't lose more than two seconds per day. Losing 15 seconds over the course of a day on your watch is not normal. Possibly, there is not enough lubricant in the Rolex Datejust movement. There may be more to the problem than just the Rolex Datejust not keeping time. Wear and tear on a movement will be increased with low lubrification. Gears inside will wear out due to the additional friction.

An excellent way to ensure everything is in order with your Rolex Datejust watch is to test its accuracy.

How To Test If A Rolex Datejust Is Running Slow


The test involves checking the Rolex Datejust time every 24 hours.

The Rolex Datejust's accuracy standard is +2 or -2 seconds per day fluctuation.

If the Rolex Datejust watch was dropped on the floor or received a heavy knock. It's a good idea to repeat the accuracy-test several times to see whether the collision has caused any harm to the Rolex movement.

For the watch accuracy test, the Rolex Datejust must be fully manually wind.

  • To begin, make sure your Rolex Datejust watch is completely wound and ready to use. To wind the Rolex Datejust watch, unscrew and pull out the crown, then wind it around 40 times.
  • To set the time on the Rolex Datejustwatch, use your smartphone or a desktop clock.
  • Then start the Rolex Datejustwatch by push in the crown and tightening it properly to the watch case.
  • Set the alarm on your phone to remind you to verify the watch's accuracy in 24 hours.
  • During the day, wear your Rolex Datejust watch. If you normally take it off at night, you can do so. The watch's power reserve will keep it going all night.
  • The Rolex Datejust watch must be worn on an active wrist during the test in order for the rotor to maintain winding the watch. You may manually fill up the power reserve if you're having a physically inactive day. Use the Rolex Datejust crown to wind the movement in the evening.

Check the time on the Rolex Datejust watch after 24 hours to determine if it has stayed correct.

Results Of Rolex Datejust Accuracy Test


Compare your smartphone's time to the time on the Rolex Datejust.The difference should not be more than 2 seconds faster or slower over a period of 24 hours.

You can consider the Rolex Datejust accurate within Rolex specifications if the time on the watch is the same as your smartphone with a 2 seconds tolerance.

Repeat the test if the Rolex Datejust timepiece has gained or lost more than 2 seconds.
