About Rolex:

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.

Established by Hans Wilsdorf in 1905, Rolex is by far the most iconic and legendary luxury watchmaker in the industry. Its fame is mythical and unmatched, and rightly so: Rolex makes among the very best automatic/mechanical watches in the industry with extremely accurate, reliable, durable, shock resistant, anti-magnetic and robust movements, the best steel grade in the industry (904L stainless steel), unmatched build quality, unmatched reputation, and unmatched resale value.

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, all movements are chronometer certified and 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 is to keep things simple, down to earth, limited 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. 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 broke, don’t fix it”.

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

Rolex is a super conservative and super 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 mechanically speaking larger components than ETA/Valjoux movements, which means that Rolex’s movements are typically more robust and shock resistant. Since the 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’s success has given the manufacturer and brand enormous financial and industrial muscles, and if I’m not mistaken, Rolex alone stands for 20% of all Swiss 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.

About Rolex Sea Dweller:

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

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

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.
