About Rolex:

Rolex is one of the very few independent Swiss watchmakers left in the industry.

In 1905, Hans Wilsdorf and Alfred Davis founded Wilsdorf and Davis – the forerunner of Rolex, in London, United Kingdom. In 1908 it was renamed Rolex. Rolex moved its operations and headquarters to Geneva in Switzerland in 1919, where Rolex is located even today as we speak.

Rolex’s iconic stature

Rolex was already an established brand by the 1940s and 1950s, and became an unmatched status symbol during the 1950s and the 1960s. Rolex’s mythical and legendary prestige and reputation started in the 1980s.

In terms of production volume, fame, status and prestige, you can basically divide the Swiss watchmaking industry into two camps: Rolex, and the rest. That’s how excellent, prestigious, famous, and dominant the Rolex brand really is.

Rolex’s success has given the manufacturer and brand enormous financial and industrial muscles, and Rolex alone allegedly stands for 20% of all luxury watches manufactured in the Swiss luxury watch industry.

Outside the major corporate groups such as Swatch Group, Richemont Group, LVMH etc, Rolex is probably the only 100% independent watchmaking giant. The other independent Swiss watchmakers are dwarves in comparison to Rolex’s enormous manufacturing capabilities.

In terms of resale value, Rolex and Patek Philippe are unmatched and stand out from the crowd. Rolex has unmatched reputation, and unmatched resale value.

The manufacture of Rolex watches

Rolex makes among the very best automatic/mechanical watches in the industry with extremely accurate, reliable, durable, shock resistant, anti-magnetic and robust movements, amongst the best steel grades in the industry (904L stainless steel), and with unmatched external build quality.

Rolex’s watches are going through quality tests of such intensity and magnitude, that few brands out there can match Rolex.

All Rolex’s movements are in-house made by Rolex, and all movements are chronometer certified. The accuracy rate of Rolex’s movements is equivalent to 99.998%.

All Rolex’s movements use the so called parachrom hairspring. This technology is very particular and unusual because it is 100% anti-magnetic and 10 times more shock resistant than ordinary hairsprings! This makes all the difference because the hairspring sits inside the balance wheel, which is the very heart of an automatic/mechanical movement.

Rolex’s philosophy and approach to watchmaking

The brand is famous for its robust and water resistant steel sports watches, and that’s pretty much what defines the brand.

Rolex’s philosophy is to keep things simple, down to earth, goal oriented and focused. Rolex rarely makes movements with complications – meaning haute horlogerie (fine watchmaking or the high art of watchmaking).

Rolex’s movements are stellar but simple meat and potatoes movements, focused on the basic time functions, that most people actually need and want – meaning hour-, minute-, and second hands and a date window.

It takes Rolex a considerable amount of time – sometimes decades – to make the slightest changes in either their technology or design. Rolex’s philosophy is: “if it ain’t broken, don’t fix it”.

Rolex isn’t about technological revolution. Rolex is about technological evolution, and optimizing and improving the already existing technology slowly and gradually over time.

Rolex is a very conservative and exceedingly reliable brand. If you purchase a Rolex, you know what you’ll get.

Rolex’s movements aren’t decorated at all, and their movements typically use physically larger components than the ETA/Valjoux movements, which means that Rolex’s movements are typically more robust and shock resistant. Since Rolex’s movements are so robust, and typically use larger and fewer components than most movements out there, it means Rolex is capable of fixing and repairing your movement in a very short period of time.

Rolex Quality Tests:

Rolex watches have consistently proven that they can be used in the most extreme situations you can think of – including deep sea diving and mountaineering.

The bracelet and the clasp:

  • The famous Rolex bracelet and clasp – the oysterlock, undergoes 26 drop tests of various kinds.
  • The oysterlock is also submerged into tanks filled with chlorine, and salt water. Sand is added to the test hundreds, if not thousands of times – 3 times the clasp’s expected durability. The purpose is to simulate extremely harsh conditions. Every oysterlock must pass this test.

One of the most demanding tests used by Rolex:

  • Rolex watches are submitted to a crash test where the impact is equivalent to 5000 G (5000 G-Force) – considerably more severe than a car crash. After being submitted to this test, Rolex watches are still expected to be fully functional, to retain the highest level of movement accuracy and reliability, and to be entirely intact.

Rolex water resistance tests:

  • Rolex uses extreme water resistance tests – 10% greater pressure than the water resistance given on the dial, and 25% greater pressure than the water resistance level given on the dial of Rolex divers watches.
  • Rolex Oyster Perpetual watches have actually been tested to be water resistant down to at least 100 meters.

Rolex also tests their watches in order to simulate ageing and daily wear and tear:

  • Rolex applies advanced machinery and robots to simulate the movements done by your hand and arm for years, only this highly intense and extreme test is done in a week.

Rolex’s movement accuracy:

  • The Rolex movement accuracy must fulfill the criteria set by COSC. Rolex’s accuracy rate is equivalent to 99.998%.

About Rolex Sea-Dweller 4000:

Rolex has many iconic collections, and one of those is the Rolex Sea Dweller.

Today, there are two versions of the Sea-Dweller. The smaller version (Sea-Dweller 4000) is water resistant down to 1,220 meters/4,000 feet, while the larger version (Sea-Dweller Deepsea) is water resistant down to 3,900 meters/12,800 feet.

In 1967, Rolex launched the famous Rolex Oyster Perpetual Sea-Dweller which is the ultimate divers watch collection invented and manufactured by Rolex. The original Rolex Sea-Dweller was water resistant down to 610 meters.

In 1978, Rolex launched the Rolex Sea-Dweller 4000. “4000” refers to its depth rating – 4,000 feet. This is the smaller version within the iconic Sea Dweller Collection.

Opting for a Rolex Sea Dweller means you are getting one of the world’s very best divers watches that money can buy.

The New 2017 Version Of The Rolex Sea-Dweller 4000

In 2017, Rolex released a new version of the famed Rolex Sea-Dweller 4000. Instead of using the older 3135 movement, the 2017 version of the Rolex Sea-Dweller 4000, relies on the 3235 movement. The older version had a 40mm case diameter, and the newer version has a 43mm case diameter. The older version (pre-2017) of the Rolex Sea-Dweller 4000 had no magnifying lens over the date window, while the newer version does have a magnifying lens over the date window.

Physically and aesthetically very similar to the Rolex Submariner, the new Rolex Sea-Dweller 4000, comes with a larger case diameter and a thicker case, an automatic helium escape valve, and a water resistance of 1,220 meters/4,000 feet.
