Seventh, THE OYSTER CASE. Very few people around the world are able to inside a Rolex Oyster. In fact, open the sealed case need a massive torque of five Newton meters. The back of any Oyster can protects the movement from shocks, pressure, dust, water and any other damages.

Eighth, SUPERLATIVE CHRONOMETER. There is a important institute should be indicated—COSC which is the acronym of Contrôle Officiel Suisse des Chronomètres. This is an independent and not-for-profit association. Every watch must prove its super precision in a variety of extreme positions and temperatures.

How about the bezel? You can easily grip the new coin edge underwater. Furthermore, if you make its way around the dial you can hear a nice “click ” sound. Besides that, the markings on the bezel fit the dial markers and hands perfectly. You will feel the artistic value when you see it.

The whole dial is very clear because of the oversized markers and the large hands.

SPO applied both sides with the Sapphire crystal which has an anti-reflective. However, some people said that this is not a sensible choice. From the technology point, some impact from rigid things will scratch the coating on the top of the crystal; from the aesthetic point, it will add some blue view of the crystal from some lighting angle.

The bracelet of the SPO is really heavy and thick. It does not taper as most other watches. The bracelet top and bottom have a brushed finish, and the sides are polished.

The SPO uses the two-button deployment clasp with integrated diver suit extension. The clasp can easily open and close, but feel very study.  The large

The most important part is the movement. There are 29 jewels in it, the most great advantage of it is that the friction has been reduced largely. What is more, the Caliber 2500 uses a free-sprung balance to improve the timing precision. 25, 200 VPH speed is also incredible.

Apparently, the Seamaster Planet Ocean is really a creative, classic art.

Firstly, THE MOVEMENT. It has the peculiar self-winding Oyster movement which is entirely researched and manufactured by Rolex. Every movement is an officially certified Swiss chronometer.

Secondly, THE PARACHROM HAIRSPRING. Rolex researched the blue Parachrom hairspring in five years. Crafted from a paramagnetic alloy, it is unaffected by magnetic fields and up to 10 times more resistant to shocks. In the past, the unique blue colour of the hairspring was a representative of prestige, which can only use in the most accurate timepieces. But today, it serves for Rolex.

Thirdly, THE CERAMIC BEZEL. Rolex choose the ceramic to make the bezel. Ceramic has the excellent performance in resisting corrosion, color remains from affecting by ultraviolet rays and protection from scratching.

Fourth, 904L STEEL. 904L steel has been used to make the steel watch cases. Because it can resist against corrosion, 904L steel is usually served for the chemistry industry. Besides this, 904L is also a highly polishable and extremely resistant alloy.

Fifth, A CLASSIC ART. Every Rolex is the product of know-how and artistry from watchmakers, designers, gem-setters and chemists.

1, A ‘genuine’ Rolex is perfect in every aspect as in detailing, quality and craftsmanship. ioioi advice you to visit your local Rolex Dealer and inspect  different types of Rolex watches. Question your sales representative on various features of a genuine Rolex watch. You will see more about its uniqueness, functionality etc.

2, Check the Rolex Report which is an Unauthorized Reference Book for the Rolex Enthusiast, 4th Edition by John E. Brozek. More than 300 pages of relevant material which saves research time when one is considering to purchase a genuine Rolex, especially if it is a pre-owned watch.

3,In essence, look between its bottom lugs (part where the band connects to case), top lugs and opening the case back. This is the best way to distinguish between a ‘genuine’ and fake Rolex.

a) Clear Case backs – Notice that Rolex does not make watches with clear case backs. So if you find a watch which has a clear case back it is definitely not a ‘genuine’ Rolex watch.

b) Engraved Case backs - No logos or slogans are engraved on a Rolex case back. You won’t even find any engravings on it. The only exception to this case is the Ladies model (circa 1990’s) and the ‘Sea-Dweller’ model.

c) Hologram Stickers – A simple way to distinguish between a fake and a ‘genuine’ is to check the case back. A ‘genuine’ Rolex watch comes with a 3-D hologram-encoded sticker on the case back. Moreover you can clearly identify the Rolex ‘crown’ trademark which is place right above the case reference number. In most cases, the 3-D effect is not even identifiable in a fake hologram sticker.

d) Date Magnification – Common errors made by replicas include the cyclops being much smaller and not aligned properly, a large font date is another feature to fool a customer. With the case of genuine watches, all of the genuine ones feature the cyclops that magnifies the date by 2.5x, the only exception being the ‘Sea-Dweller’.

e) Triplock Crown Seal – The three Rolex models, namely the Sea-Dweller, Submariner and Daytona feature the ‘Triplock crown’. While a replica does not have a seal, a genuine Rolex uses the extra seal by the rubber o-ring on the winding tube. This is worth a mention as many original Rolex parts and accessories can also be replaced by fake ones, and so in the cases of pre-owned Rolexes this should be kept in mind.

f) Micro-etched Crystal – The Rolex ‘coronet’ or ‘crown’ just under the 6 o’clock marker was micro-etched on all Rolexes from the year 2002. If you use a jeweler’s loupe, you will notice that in comparison to a replica, the ‘genuine’ crown is much more evident and robust. In addition, fake ones have a poor overall design.

g) Size and Weight – although it is not the most scientific method for determining a fake, it should be noted that genuine Rolex watches are very sturdy and therefore relatively heavy. Fake watches are made from cheaper materials and typically feel very light. Also, the bands on genuine Rolex watches are full whereas fakes often display hollow links.

h) Hand Movement – The second hand on a genuine Rolex watch features a smooth and continuous movement that often cannot be duplicated by fake watches. Their movements are often in small, jerky increments.

i) Sapphire Composition –Many faux-Rolexes will use regular glass instead of true sapphire crystal. A good test of the materials is to check the water surface tension. A smeared film of water will pull together on sapphire due to the extremely smooth surface.

j) Lettering – Be sure to check the dial of your potential purchase to see if the lettering is precise. Under high-magnification, the type should reveal clean edges not found in many forgeries.

k) Case Reference Numbers – The serial and case reference numbers can be found in between the lugs on the side of the case. Genuine Rolex numbers are engraved with great detail and are very smooth. The numbers on fake watches often look “sand-blasted” or are roughly etched into the case.

4, Most important is—- All genuine Rolex are produced in Switzerland. ioioi suggest you to go to Switzerland and buy your favorable Rolex? You have more choices there. What is more, you could buy the genuine one. You have even made an important decision to purchase such an expensive watch, why not spend a little money to buy the “insurance”. Enjoy yourself in Switzerland!
