3 Reasons why Rolex Daytona is running slow

Why is my Rolex Daytona running slow?

The accuracy of your Rolex Daytona reflects the health of the watch. Rolex Daytona must be accurate. Rolex specifications tell you that the watch can't lose or gain more than 2 seconds per day.

A Rolex Daytona running too slow is a symptom. To restore the accuracy of your watch is important.

Here are the most common factors that could explain why your Rolex Date is running slow. There is a simple way to diagnose your Rolex Daytona and know if you need to send it for service.

Reasons for a Rolex Daytona running slow

You have multiple flashing lights on a car dashboard that will tell you when your car needs servicing. There are no warning lights on a watch to let you know that it is time to have your Rolex Daytona service.

Most people will notice if their Rolex Daytona has a serious malfunction, but early signs are often hard to notice. The reason why it is important to spot these early signs is because the sooner you have your Rolex Daytona serviced, the cheaper it will be to fix. If you wait for the Rolex Daytona to break down before you send it to a Rolex Service Centre, the repair cost will most likely be a lot more.

A simple test can give you early indications that something is not right with your Rolex Daytona. The test is a time accuracy test.

Rolex Daytona is an accurate timepiece. The company standard is +2/-2 seconds per day. It means that your Rolex Daytona should not gain or lose more than 2 seconds per day.

There are several reasons why a Rolex Daytona is no longer accurate, including but not limited to:

Rolex Daytona Shocks and Impacts

If the Rolex Daytona has been dropped on the floor or suffers a significant impact, the watch movement could be affected. Rolex Daytona is not an electronic quartz movement; it's a mechanical watch with many delicate parts:

  • the mainspring, which powers the watch
  • the balance wheel and hairspring, which oscillate to measure the time
  • the escapement, which allocates the oscillator pulses
  • the gear train, which transfers the power
  • the dial train, which moves the hands
  • and more

Each element is precisely positioned on the calibre to make the watch accurate. Rolex movement is robust, but a violent impact can displace one or more elements. After an impact, a loss of accuracy is an indication that the watch movement has been damage.

After an impact, it a good idea to test the Rolex Daytona accuracy for 48 hours. If the time remains accurate, it will be good to know that the impact has not affected the Rolex Daytona. However, if the watch is losing more than 2 seconds every 24 hours, the impact has affected the watch. How seriously? Is it difficult to know, but the watch needs to be examined at a Rolex Service Centre.

Rolex Daytona Water Damage Consequences

A Rolex Daytona running slow could be a side effect of water damage. Water and condensation leaves dirt, sand and mineral residue inside the Rolex Daytona. You must send your Rolex Daytona to a Rolex Service Center immediately if water or condensation has penetrated it. In the case of a Rolex Daytona, any type of water will damage the movement; however, saltwater poses the greatest risk.

Whatever the reason, the Rolex Daytona is in need of immediate service. When the Rolex Daytona is not serviced in a timely manner, the internal damage will increase and the cost of the overhaul Rolex repair.

Too often, people use DIY methods found on the internet, such as uncooked rise or placing your Rolex Daytona on a heater, which will not dry their Rolex Daytona. These methods are not suitable for high-end mechanical watches like the Rolex Daytona.

Moisture and deposits are still trapped inside the Rolex Daytona and will slowly damage the movement. A Rolex Daytona running slow could be an indication of a movement deteriorating. In the worst-case scenario, a sign of rusting. A Rolex watchmaker is the only one qualified to rescue a Rolex watch after a water leak.

If you know, the Rolex Daytona has been water damage. There is no need to test its accuracy. You need to send the watch for service as soon as possible.

Rolex Daytona is Running Dry

The Rolex Daytona needs lubricants to remain accurate and to reduce friction between the various moving parts. The term 'running dry' is used by watchmakers to indicate that the watch's lubricant level is too low.

Typically, Rolex lubricants last between five years and ten years, but that is a general timeframe. Is it ten years from the time of purchase or ten years from the time the watch was manufactured? How long between the time of manufacturing and the time you purchased the watch? There are some unknowns about the actual lifespan of lubricants.

Rolex uses a specific lubricant that evaporates when drying. When the lubricants are low; they need to be replenished. The operation is carried out by a qualified watchmaker who knows precisely the type of lubricant to use, where and how much needs to be applied.

A symptom of lubricant running low is the Rolex Daytona losing few seconds per day. A Rolex Daytona running fine should not lose more than 2 seconds per day. If the watch is losing, say 15 seconds per day, that is no normal. A possible explanation is a lack of lubricant. If it the case, the problem is not only that the Rolex Daytona is not keeping time. Low lubrification will increase the wear and tear of the movement. The added friction will worn-out the gears inside.

Testing your Rolex Daytona accuracy is an excellent way to check that everything is ok with your watch.

Testing Rolex Daytona Accuracy

During the test, you will check the time on the Rolex Daytona every 24 hours. A Rolex accuracy specification for the Rolex Daytona is +2 or -2 seconds variation per day.

If the Rolex Daytona suffered a hard knock or fell on the floor. It is good to do the accuracy multiple times to know if the impact has damaged the Rolex movement in any way.

The Rolex Daytona Needs to Fully Wound for the Accuracy Test.

Start by ensuring that your watch is fully wound and ready. Unwind the crown, then wind your Rolex crown around 40 times.

Use a smartphone or your desktop clock to precisely set the time on the Rolex Daytona.

Start the Rolex Daytona by pushing in the crown and screw it down correctly.

Set the alarm on your smartphone for 24 hours to remind you to check the watch accuracy.

Wear your Rolex Daytona during the day. You can take it off during the night if you usually do it. The power reserve will keep the watch running through the night.

The Rolex Daytona, during the test, needs to be worn on an active wrist for the rotor to keep wind the watch. If you are having a physically inactive day, you can top up the power reserve manually. In the evening, use the Rolex Daytona crown to wind the movement.

After 24 hours, when the alarm sounds, check the time of the Rolex Daytona to see if it has remained accurate.

Rolex Daytona Accuracy Results

Compare the time on your smartphone and the time of the Rolex Daytona.

Within 24 hours, the difference should not exceed 2 seconds faster or slower.

If the time is the same (+2s/-2s), the Rolex Daytona is accurate, and the watch is fine.

If the Rolex Daytona watch has gained or loses more than 2 seconds, then repeat the test once more. If the results remain the same after each test, there may be something wrong with your watch and it should be sent for servicing. A Rolex Cosmograph Daytona Service will test the watch calibration more scientifically and locate the source of the problem.
