How Do Rolex GMT Master II Keep Time So Well?


Rolex GMT Master II watches are incredibly accurate mechanical timepieces, but external factors can influence how accurately they keep time. Rolex is renowned for its precision in part due to its iconic Perpetual movement. Another question interested parties ask themselves is is it worth to buy a Rolex?

How many seconds a day is a Rolex off? The Rolex movement is certified by the Swiss Official Chronometer Testing Laboratory (COSC). As a result, Rolex GMT Master II has a maximum time deviation of less than -4 to +6 seconds per day. Nonetheless, these are some of the factors that can impact your timepiece's accuracy: altitude and temperature, how often you wear your Rolex GMT Master II, and the position in which you store the Rolex Perpetual.

The Rolex Parachrom Hairspring is arguably the most stable and accurate mechanical movement ever created, even though a mechanical movement won't keep perfect time like a quartz movement. All Rolex watches today are battery-less, except for their Oysterquartz model that was discontinued in 2001. Rather, they use an internal perpetual rotor to maintain precise timing. In other words, a Rolex GMT Master II is an 100% mechanical watch. For more information about Rolex service costs follow the link to the dedicated article. Watch wearers keep the perpetual movement of the Rolex GMT Master II running by naturally moving their wrists. In order to keep the mainspring running and functioning correctly, its perpetual rotor is dependent on the wearer's wrist movement.

Does Your GMG Master Watch Need Service? It's Time To Found Out


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 GMT-Master service and nothing about Rolex GMT Master II service cost

Most people will notice if their Rolex GMT-Master 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 GMT-Master serviced, the cheaper it will be to fix. If you wait for the Rolex GMT-Master 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 GMT-Master. The test is a time accuracy test.

3 Reasons Why A Rolex GMT Master Movement Is Running Slow


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

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

1. Rolex GMT-Master suffered a high impact

If the Rolex GMT-Master has been dropped on the floor or suffers a significant impact, the watch movement could be affected. Rolex GMT-Master 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 GMT-Master accuracy for 48 hours. If the time remains accurate, it will be good to know that the impact has not affected the Rolex GMT-Master. 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.

2. Watches low on lubricants

The Rolex GMT-Master 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 GMT-Master losing few seconds per day. A Rolex GMT-Master 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 GMT-Master 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 GMT-Master accuracy is an excellent way to check that everything is ok with your watch.

3. Watches Water Damage Aftermath

Water damage can cause a Rolex GMT-Master to run slowly. Dirt, sand, and minerals are left inside Rolex GMT-Masters by water or condensation. If water has penetrated your Rolex GMT-Master, you need to take it to a Rolex Service Center right away. The movement of a Rolex GMT-Master is susceptible to damage from any type of water, but saltwater is most dangerous.

The Rolex GMT-Master needs repair immediately, no matter what the cause. Rolex GMT-Master watch repairs will become more expensive if internal damage is not addressed in a timely manner.

The Rolex GMT-Master still has moisture and deposits inside, which will slowly damage the movement. When a Rolex GMT-Master runs slow, it may be an indication that the movement has deteriorated. The worst case would be rusting. Rolex watchmakers are the only ones qualified to mend a Rolex watch that has suffered a water leak.

You are probably aware that Rolex GMT-Master if has been water damaged. Testing its accuracy isn't necessary. I would recommend that you send the watch in as soon as possible for service.

Checking If The Rolex Need Servicing


Testing the precision of a Rolex GMT-Master

The test involves checking the Rolex GMT-Master time every 24 hours.

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

If the Rolex GMT-Master 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 accuracy test, the Rolex GMT-Master must be fully wound.

To begin, make sure your Rolex GMT-Master is completely wound and ready to use. To wind the Rolex GMT-Master, unscrew and pull out the crown, then wind it around 40 times.

To set the time on the Rolex GMT-Master, use your smartphone or a desktop clock.

Then start the Rolex GMT-Master 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 GMT-Master. 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 GMT-Master 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 GMT-Master crown to wind the movement in the evening.

Check the time on the Rolex GMT-Master after 24 hours to determine if it has stayed correct.

Results Of Rolex Models Accuracy Test


Compare your smartphone's time to the time on the Rolex GMT-Master.

The difference should not be more than 2 seconds faster or slower over a period of 24 hours.

You can consider the Rolex GMT-Master 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 GMT-Master timepiece has gained or lost more than 2 seconds.

If multiple tests confirm that the Rolex GMT-Master is not accurate, there may be a problem with your watch movement, and it should be serviced.

A Rolex Service Center will conduct a more thorough examination of the watch calibration and pinpoint the root of the issue.
