The 5 Most Accurate Watches in the World

The 5 Most Accurate Watches in the World

Everyone wants an accurate timepiece but which one and how do we define accuracy? Let's explore and find the most accurate watches here!
Mar 26, 2024

Do most accurate watches really exist? Talking about accuracy is really a gray area where there are many factors behind the process of making accurate watches. This is especially when we talk about mechanical movements where accuracy is at stake. Compared to quartz, mechanical watches are less-accurate but that doesn’t say that they aren’t accurate. 

Due to the use of many intricate parts, mechanical is more prone to shocks. In addition to that, the manufacturer has informed the wearer that mechanical movements can lose accuracy for 5 to 10 seconds per day. That will be a big matter, especially compared to quartz which claims to only lose 4 seconds per month.

In terms of accuracy, watchmakers have always put this matter as the top priority – creating movements as accurately as they could and can handle extreme temperatures, shocks, and magnetism. When looking for a new watch, accuracy becomes one important thing to consider – as the main reason to have a timepiece on the wrist is to tell the time.

To put things clearer, this article will only discuss accuracy in mechanical movements. That said, we put aside quartz for another chance and look at watches that offer accuracy at their best in this recent time.

How Do We Define Accuracy?

Accuracy is not a simple and easy thing to achieve, especially when we talk about mechanical movement. What are the most accurate watches in the world? Let’s put aside quartz first and talk about mechanical watches. There are many things that affect accuracy as mechanical watches consist of many intricate parts. 

But what is actually meant by accuracy? In the watchmaking industry, we know the term “accuracy” and “precision” – they’re not the same and can’t be used interchangeably. Many people misunderstand that an accurate and precise watch is the same thing when it is not. 

A watch’s performance is basically measured based on accuracy and rate stability. Accuracy refers to a timepiece that is exactly synchronized with Coordinated Universal Time (UTC), which is a reference point for other timezones and is 1.3 seconds fast the next day. In that case, we can say that the watch is accurate to within 1.3 seconds per day.

Rate stability refers to the ability to keep the same accuracy over a certain time interval. So, it’s not about accuracy measurement but rather consistency. As such, if your watch can maintain a stable rate, then you can claim it as a precise timepiece.

For example, a timepiece has a daily rate variation of -10 seconds. The following day may be +8, then -6, then -4, and then +3. Then after several days, the watch is back and synchronized to the time standard. It means that you have an accurate watch but not a precise watch. The watch can get back to its standard time but the interval isn’t consistent.

5 Most Accurate Watches, Gnomon’s Pick

Now that we have settled on how we define accuracy, below are our top picks for the most accurate watches. Let us remind you again that the watches listed below are driven by mechanical movements.

Mido Ocean Star 600 Chronometer Black 

The first list of the most accurate watches that we would like to suggest is Mido Ocean Star 600 Chronometer Black Ref. M026.608.11.051.00. The watch is driven by Mido Calibre 80 COSC which is based on the  ETA C07.821 movement. It beats at 21,600 bph and has 25 jewels to reduce friction in the moving internal parts.
