The Founder of Rolex Hans Wilsdorf, who created this name “Oyster” to the World’s first waterproof wrist watch in 1926. All Rolex Oyster are warranted pressure proof to a depth of minimum 300 feet/100m and for some special model up to 4,000 feet.
How the oyster case is made
Each of the Oyster case is stamped out from a solid block of stainless steel, 18kt solid good or solid platinum. I remember that the TV ad in 1985 had this description:” Each Rolex Oyster case is made at least 162 separate operations are necessary to transform the metal block into an Oyster case, a further 32 operations are needed to manufacture the Twinlock winding Crown, nearly all finishing is done by hand”.
The Pressure-proof case
After we have made a strong flawless solid case, the next challenge is the pressure–proof concern. This is a major problem for watch makers for a very long time. There are three areas that we have to seal, the case, the winding crown and the crystal case.
Oyster Case
Rolex found an excellent answer to this question. The high precision and great care that are presented thorough the manufacturer of an Oyster result in case is virtually a miniature “Safe”, extremely strong and practically indestructible.
Twinlock and Triplock
Traditional Winding stem of a wrist watch presents one of the main obstacles to waterproofing; Rolex overcame it with the invention of a winding crown that crews down on to the case.
Twinlock crown interprets double protection requires no les than 32 operations. It is machined with exacting precision and screws on to the case. It can be compared as the hatch of a submarine and is fully effective in protecting the movement, make it a solid single piece, water tight safe! The Triplock crown offer triple protection and this invention were perfected by Rolex for its diving watches. Some of these models are warranted pressure-proof to depth of 1,000 feet, 2,000 feet even 4,000 feet. The tree dots on the winding crown make it easy to distinguish a “Triplock” from a “Twinlock”.
Crystal and the case
The crystal or watch glass is either made of a scratch-resistant synthetic sapphire or a virtually unbreakable plastic material, both fir the case with precision, Then the bezel, is inserted, primarily for decorative purposes. Finally the back is screwed into the Oyster case and a combination of extremely accurate threading and a special joint o-ring inured a perfect pressure-proof seal for all oyster cases.
The Oyster Case is a chunk of heavy Solid Gold
I used to wear Oyster Day-Date as they have only Gold versions, the whole piece of Watch is made of solid gold. Gold is one of the precious metal, it does not oxide easily and it is highly resistant to corrosion, being a symbol of wealth and a store of value throughout history. Gold watch is having a 3 times the price of the Stainless steel Rolex.
The Rolex OysterQuartz 18kt Yellow gold Day-date weighs 3.73 tael, approx. 144 grams.
An Oyster Perpetual 18kt yellow gold Day-Date weighs approx 3.5 tael,
The gold value is approximately HKD$35,000. USD$4,300.00!
If the Quality of the watch is recognized first because of its technical excellence. It is noticed even more when the famous wear it. It is quite common that Rolex has been selected by the leaders of industry, exploration, mountaineering, engineering, the arts, science, the military, the oceanographic field, celebrities, performing artist., racers, CEOs, movie star., Note that the name of “Rolex” has been first appeared in the Movie “Die Hard” as John McClane wife Holly received s lady Datejust two tone as a gift form her company.
If I am asked to choose all time favourite watch, I have no hesitation to select Rolex Day-Date yellow gold! As it is durable, reliable, Sportive, waterproofing, shock-resistant, beautiful, accurate and Most important… affordable…
Rolex Solid Gold watch is one of the watches that you can buy under the budget.
