What is the difference between the Rolex watches "Perpetual Date", "Oyster Precision" and "Datejust"?

Hello.

This is Senoo from Vintage Watch Life 😊

In this video, we explain the differences between the Perpetual Date, Oyster Precision, and Datejust.

I will explain this in a very simple way so that even beginners can understand.

If you watch this video until the end, you will be able to roughly understand the differences between the two models, so please stay with us until the end✨

What is the difference between the Perpetual Date, Oyster Precision, and Datejust?

There are many different Rolex models, and from a beginner's perspective, what are the differences?

You can see things like this here and there.

So, let me explain the differences between these three models.

Let's first organize the words that appear in Rolex.

If you understand these things, I think you will be able to understand 50% of vintage Rolex models.

First, let's break down these words:

There are ``Perpetual'', ``Oyster'', ``Precision'' and ``Date''.

Breaking down each of these words

Perpetual = means that it is equipped with an automatic winding mechanism

・Oyster = means that you are using an oyster case

・Precision = not a chronometer, but it is a standard of the same order.

・Date = means that the watch has a date display

If any of these are installed, they will be included in the model name.

Now, let's take a look at the images and check it out.

The difference between the Perpetual Date, Oyster Precision and Datejust

From the left, they are the Oyster Date Precision, the Oyster Perpetual Date, and the Oyster Perpetual Datejust.

Now let's break these words down and take a look at them.

The Oyster Date Precision contains the indices "Oyster," "Date," and "Precision."

So, since it does not have the word "perpetual," which means automatic winding, we can see that it contains a manual winding movement.

The movement Cal.1225 used in the Oyster Date Precision
By the way, this is the Cal.1225 movement.
The model in the middle The 'Oyster Perpetual Date ' contains 'Oyster', 'Perpetual' and 'Date'.
So it's the same as the Datejust.
Now to the main topic: what is the difference between the Date and the Datejust?
I will explain what this means.

What is the difference between the Oyster Perpetual Date and the Oyster Perpetual Datejust?

The main difference between the two models is the size.

The Date has a case diameter of 34mm, while the Datejust is 36mm.

In conclusion, the only difference is the size!

It ends with:

But there's also history involved.

Rolex's three inventions

I'm sure you know that it has a "perpetual mechanism," "Datejust," and "Oyster case."

Looking at its history chronologically , the Datejust was born in 1945, a model equipped with the Datejust function, which instantly changes the calendar around midnight .

Next, the Oyster Perpetual Date, which appeared in the 1950s, did not have this "Datejust function" when it was released, and the calendar changed slowly around midnight.

Therefore, the current Datejust is a model that is complete by combining all of these functions.

Later, in the 1970s, the date watch was also equipped with a movement that included the datejust function, and the functions were the same, only the size was different.

And obviously, the more features a model has, the more expensive it will be.

That's why the Datejust is the most expensive of Rolex's simple line of three-hand models.

summary

If we break the words down, we can see what functions they have.

I understand that.

When you think of Rolex, you probably think of automatic watches, but they also made hand-wound watches like this one, and there are many wonderful vintage models.

It seems like choosing a watch would be more fun if you carefully consider the features you need and talk to yourself about your daily life.
