Questions about Buying a Rolex

What is a Rolex?

A Rolex watch is a luxury timepiece crafted from the finest raw materials and expertly assembled with meticulous attention to detail. An extremely sought-after brand, the Rolex takes on a role beyond that of a mere timekeeper. They are widely considered to be a status symbol, and depending on the model, can be used for several different types of activities, from expeditions and deep-sea diving to special events and dinner dates.

Why are Rolex watches expensive?

As they are considered a luxury, Rolex watches tend to have a 4-figure price tag, making them one of the most known expensive watch brands out there. They are expensive because Rolex spends its time developing more efficient manufacturing methods, as well as new techniques to stay ahead of the competition. 

With extremely high in-house development costs in both design and craftsmanship, the materials used are much more expensive than those used in a standard watch. Rolex tends to use 904L steel which is leagues ahead of most luxury market equivalents, meaning that it holds its value over time.

How do you know if a second-hand Rolex is real?

You can determine whether a second-hand Rolex is real in a number of ways, but it is important to make sure that you are buying from a trusted seller who has positive reviews and a 5-star rating on Trustpilot. 

Serial & Model Numbers

When checking the serial and model numbers, any markings should be engraved in perfect fine lines. Fake Rolex watches usually have low-quality markings that are easy to spot. In new Rolex watches, the serial number is displayed on the inner Rehaut.


Replica Rolex watches will feature low-quality stampings or will not feature any at all.

The Dial

Replica Rolex watches may feature uneven, blotchy fonts and misspellings, whereas a real Rolex watch will always be perfect.

Rolex does not engrave their casebacks – this is only done in some instances.

Here at Miltons Diamonds, we ensure that our pre-owned Rolex watches are expertly referenced against technical documents and manufacturer records to ensure originality as well as a clean history. 

When was Rolex founded?

Rolex was founded in 1905, by Hans Wilsdorf. At the age of 24, Hans Wilsdorf founded a company in London specialising in the distribution of timepieces. At this time wristwatches were not very precise, but his visionary spirit foresaw that they could become more than just elegant, but reliable too. The story began when he created the first waterproof wristwatch – the Oyster – which developed into a collection of timepieces that are still icons in watchmaking today. 

In 1908, Hans Wilsdorf created the brand name ‘Rolex’. He wanted a short, easy to say and remember name that could be used in every language. He also wanted the brand name to sit elegantly on watch movement and dials, just like it does today.  Rolex became Rolex watch Co. Ltd in 1915. 

Where are Rolex watches made?

Today, Rolex watches are manufactured in Geneva, Switzerland. As well as their manufacturing station, Rolex have their very own internal Research and Development departments across their various facilities. These well-equipped professional science labs don’t just research new watches; they look into how they can make their manufacturing techniques more efficient and effective. This highlights what a competent and organised manufacturing company Rolex are. 

Who owns Rolex?

In 1945, Hans Wilsdorf set up the ‘Hans Wilsdorf Foundation’. In 1960, he handed 100% of his ownership stake in Rolex to this foundation. This now controls Rolex to this day and donates a proportion of it’s income to charity and social causes in Geneva, Switzerland. 

Do second-hand Rolex watches have a guarantee? 

While purchasing a pre-owned Rolex watch can be a daunting experience, at Miltons Diamonds, we offer an excellent 2-year warranty on all of our Rolex watches to bring you peace of mind. 

What does the second-hand Rolex guarantee cover?

If the Rolex is still covered by the manufacturer’s warranty, the watch can be sent via Miltons Diamonds or an authorised retailer for the manufacturer to repair. If your watch is under warranty from Miltons Diamonds, this means that we will repair any faults in your watch during this time in conjunction with the manufacturer if necessary. 

Questions about the Movement and Accuracy of a Rolex Watch

What movements do Rolex watches use?

Rolex manufactures watches that use mechanical calibers which are powered by springs. All of the brand’s watches are mechanical and use either automatic (self-winding) movements or, in some cases, a manual wind movement. They do not use battery-powered Quartz movements, although this has been featured in their collection in the past.

How accurate are Rolex watches? 

Every Rolex watch is COSC certified by the Official Swiss Chronometer Testing Institute to determine whether it meets the requirements to receive the highest possible designation for accuracy. After receiving this certification, Rolex then does further testing, regulating each watch even further so that it achieves an accuracy of -2/+2 seconds per day, allowing it to achieve a second designation called Superlative Chronometer, making them exceptionally accurate. 

Questions about Caring for Your Rolex

How can I look after my Rolex?

To make sure that your Rolex watch stays in top condition, clean it occasionally with a gentle microfibre cloth and wash the case and bracelet with soapy water, unless they are made of leather. Ensure that the winding crown is screwed down against the case so that this allows the watch to remain waterproof. If your Rolex has been worn in the sea, rinse it with fresh water to remove any salt water and sand from the materials.

Do I have to wind my Rolex?

If you wear your watch every day, there’s no need to wind it because the rotor provides a constant and stable power source by transferring energy to the watch as you move your wrist throughout the day. When your Rolex is taken off and set aside, it can retain its power for up to 70 hours depending on the model. However, if your watch does lose power, wind it manually by unscrewing the crown to the winding position and turning it clockwise around 20 times, screwing the crown in afterwards.

How do I set the time on a Rolex? 

To set the time on a Rolex watch, simply unscrew the crown and pull it out to the second notch. This stops the seconds hand, allowing you to wind it to set the right time. Each type of Rolex watch has a range of different functions, which can be found in the user guide.

When do I need to service my Rolex?

To make sure that your second-hand Rolex watch remains in excellent condition, it should be serviced at least every ten years depending on the model and the level of usage.
