Rolex Oyster Perpetual Datejust Serial Number 045

Rolex Oyster Perpetual Datejust Serial Number 045

The Rolex Oyster Perpetual Datejust is one of the most iconic and popular models of the Swiss luxury watchmaker. It was introduced in 1945 as the first self-winding wristwatch with a date window on the dial. The Datejust has been worn by many famous personalities, such as Winston Churchill, Martin Luther King Jr., and Roger Federer. But how can you tell the age and authenticity of your Rolex Datejust? One way is to look at the serial number engraved on the case.


What is a Rolex serial number?

A Rolex serial number is a unique code that identifies the production year of a Rolex watch. It is usually found between the lugs on the side of the case at the 6 o'clock position, behind the bracelet. The serial number consists of four to eight digits, depending on the year of manufacture. Rolex started using serial numbers in 1926, and they have changed over time in terms of format and location.

How to use a Rolex serial number lookup chart?

A Rolex serial number lookup chart is a tool that helps you find out the production year of your Rolex watch based on its serial number. You can use online resources, such as [Bob's Watches], [Precision Watches], or [Official Rolex Website], to access a lookup chart or a calculator. You simply enter your serial number and get the corresponding year. For example, if your serial number is 045, you can use the chart below to find out that your watch was made in 1927.

What does the serial number 045 mean for a Rolex Datejust?

The serial number 045 means that your Rolex Datejust is one of the earliest models ever produced. It was made in 1927, which is 18 years before the official launch of the Datejust in 1945. This means that your watch is very rare and valuable, as it belongs to the first generation of Rolex Oyster watches. The Oyster was the first waterproof wristwatch in the world, patented by Rolex in 1926. It featured a screw-down crown and a hermetically sealed case that protected the movement from dust and moisture.

Your Rolex Datejust with the serial number 045 also has some distinctive features that differentiate it from later models. For example, it has a smaller case size of 36 mm, compared to the modern 41 mm. It also has a fluted bezel, which was originally designed to screw the bezel onto the case for waterproofness. The fluted bezel later became an aesthetic element and a signature feature of Rolex watches. Moreover, your watch has a slate dial, which is a dark grey color with a sunray finish that creates subtle light reflections.

How to verify and maintain your Rolex Datejust?

To verify and maintain your Rolex Datejust with the serial number 045, you should follow some tips and precautions. First, you should always check the authenticity of your watch by comparing it with official sources, such as [Official Rolex Website] or authorized dealers. You should also look for signs of tampering or counterfeiting, such as mismatched parts, poor quality materials, or incorrect markings. Second, you should take good care of your watch by keeping it away from extreme temperatures, magnetic fields, or shocks. You should also clean it regularly with a soft cloth and water, and have it serviced by a professional every five years.

Your Rolex Datejust with the serial number 045 is a precious and historical timepiece that deserves your attention and respect. It is a testament to the innovation and excellence of Rolex, and a symbol of elegance and prestige. By using a Rolex serial number lookup chart, you can learn more about your watch and appreciate its value and beauty.
