Rolex Deepsea VS. Sea-Dweller

Both the Rolex Deepsea and the Rolex Sea-Dweller 4000 have amazing water resistance so let’s compare these two very great diver’s watches that are favorites among the professional divers in the world. For starters, during the testing these two watches have both gone through some of the harshest conditions known to man and have both passed with flying colors. There is a $1650 difference in list price between these two watches. After reviewing the unique features of each, it’s up to you to decide if the extra features are worth it to you or not. Read further for the full scoop on each watch. We will list all the common features, then all the unique features of each watch. Or click here for the side by side basic specifications.

Other than the case size, the main difference between these two watches is their resistance to unimaginable pressure. In terms of water resistance, the Rolex Deepsea would certainly take the prize for water resistance with a very impressive 12,800 feet / 3900 meters of water resistance compared to the Dea Sweller 4000 which has 4,000 feet / 1,220 meters of resistance. To get an understanding of the amount of pressure the watch can go under, there are 5548.99 pounds per square inch (PSI) of pressure at a depth of 12,800 feet and 1734.06 pounds of pressure (PSI) at 4,000 feet underwater.

Another noticeable differentiating feature would be the Helium escapement valve located on the Rolex Sea-Dweller Deepsea. While both of these watches are part of the Rolex Sea-Dweller series, only one of them has the name Deepsea printed on the dial just below the Rolex logo. This is a designation reserved for a diver watch that has a tough as nails 5mm domed sapphire crystal set in a patented 3-piece case with the Ringlock System, a practically indestructible nitrogen alloyed stainless steel support ring set inside the case this is a watch that can handle the type of pressure that would literally crush a submarine!

The Silicon Revolution: Entering a New Era in Watchmaking

Let’s examine silicon and how the world’s best watchmakers use it in their most innovative movements.

It’s no secret that with all the electronic equipment that surrounds us each day, between cellphones, tablets, monitors, TV’s, airport security scans, and more, we are exposed to higher levels of EMFs or electromagnetic frequencies. This is probably the worst thing that ever happened to mechanical watches as we know it since the Quartz crisis. Luckily, luxury watchmakers are using a space age material to combat these forces.

Silicon (also known as silicium) found a new place in watchmaking and has gained momentum in the last decade or so. This material has incredible resilience when it comes to shock and is impervious to magnetic interference. Watchmakers are seeing the value in adopting this versatile material that is lighter yet harder than steel into their engineering. It improves stability, performance, accuracy, and resistance to magnetic interferences and thermal fluctuations. It also can keep its shape forever and never requires any lubrication.

The most common use of silicon in a watch movement is the balance spring or hairspring. The combination of these two parts together is called the oscillator. The hairspring is one of the smallest components in a watch but also is one of the most critical in keeping the watch precise.

The oscillations in the movement depend on the balance spring to stay accurate. The less affected the hairspring is to external influences such as shock and electromagnetic interference, the more precise the movement will be.

2020 rolex tudor watch Price increase

From January 1, 2020, Rolex has increased by 3-5% in the whole line. Compared with the price adjustment in 2019 (there are rises and decreases), this comprehensive price adjustment still shows that Rolex replica watches is very confident in the short-term sales situation and shipment volume of the brand in 2020. In the current downturn in the export of Swiss watches and clocks and the impact of smart watches on traditional watches, Rolex’s counter trend has attracted the attention of the industry.

There are many reasons for Rolex’s price rise, such as the rise of raw material price and currency depreciation. However, frequent price adjustment is not a smart measure for consumers. But for Rolex, as long as the quality is strong enough, the brand can not be sold.

Replica Tudor watch up 2% – 10%

With Rolex advance and retreat of the tudor replica watch , of course, can not avoid the price rise of this move, and compared with the big brother Rolex, the price rise is relatively bold. For example, popular small copper flowers, up nearly 10% of the price.

After the announcement of China’s tariff reduction measures, it is easier for luxury goods to enter China, and the price gap between domestic and foreign luxury goods is gradually narrowing. Of course, this price adjustment is not only in mainland China, but also in the global market.

For consumers, the price rise is bound to be detrimental to their “wallet”, extend the after-sales period, strictly abide by the quality demand, and the rise of currency. These reasons cause the final result of the above-mentioned brand price increase. Maybe it is true that the old saying “buy early, enjoy early”? Of course, all purchasing behavior must be within the scope of their own ability.

Better Discounted Pricing
You can usually find better discounts on a brand such as Omega compared to Rolex. This has to do with the differences with the prestige of the brand itself as well as the resale value

Accuracy & Precision
The Aqua Terra (NON-quartz) collections use a COSC certified chronometer, the highest designation that a watch can get from the Official Swiss Chronometric Testing Institute known as COSC (Contrôle Officiel Suisse des Chronomètres). The COSC chronometer’s impressive accuracy of -4/+6 seconds per day doesn’t have the same precision as the Rolex Superlative chronometers which is -2/+2 seconds per day
Resale Value
The resale value on Omega watches is typically less than that of a brand like Rolex which has one of the highest resale values among luxury watch brands
Brand Prestige
The Omega brand doesn’t have the same prestige as the Rolex brand which has the highest brand recognition in the luxury watch industry

Brand Prestige
In terms of prestige, the Rolex brand is par none, the most recognizable brand out there with almost 100% brand recognition worldwide, while Omega watches has closer to 70% which is also amazing. So as far as which watch is a bigger status symbol, one would have to say that the Omega Aqua Terra watches are slightly behind Rolex Explorer but are still considered dream watches to many people.
Accuracy & Precision
Rolex Explorer watches have a superlative chronometer designation which has an accuracy of -2/+2 seconds per day which is 2 to 3 times more precise than the Omega Aqua Terra’s COSC certified chronometers with -4/+6 seconds per day, which is still a very impressive and accurate movement.
Resale Value
Resale value is typically higher on Rolex watches compared to Omega watches

Available Models
Rolex Explorer series has a much smaller collection of watches with two watches in the Explorer 1 series and two more watches in the Explorer II series
Price
The least expensive Replica Rolex Explorer costs more than the least expensive Omega Aqua Terra
Lower Discounts

Buying an even slightly more prestigious watch comes at a price. You usually can’t get the same types of discounts on a Rolex compared to a brand like Omega. This has to do with the esteem and prestige of the Rolex brand as well as the greater resell value.

Replica Rolex Yacht-Master VS Yacht-Master II

A detailed comparison on these two luxurious Rolex sport watches.

The Yachtmaster II and Yachtmaster 40mm are both great sports watches especially with professional sailors and yacht racers. They both are classy and sporty at the same time. But what are the key differences and what makes these two watches special in their own way? Have a look below at a detailed description of the differences.

Let’s take a look at one of the latest and most spoken about Replica Rolex Yacht master watches, the 116655. This watch is a special watch for many reasons. Namely, this is a historical landmark for Rolex since it is the first Rolex watch to ever use a rubber strap. Most people wouldn’t bat an eye at the idea of a Rolex with a rubber strap so why the fuss? This is not any typical rubber strap. Rolex has been raving about this new rubber Oysterflex bracelet which is not only very comfortable to wear, it is also hypoallergenic.

The research and development team at Rolex has engineered a bracelet that is as easy to wear as a rubber bracelet but also holds its shape like a metal bracelet. They do this by using nickel-and-titanium inserts inside the band. They also instituted a patented shape on the inside of the bracelet which has a cushioning system built-in to it which allows the bracelet to take the natural shape of a wrist making the Oysterflex possible the most comfortable rubber watch band. An Oysterlock safety clasp keeps the watch from opening and looks stunning in 18ct Everose gold. Everose gold is a patented 18kt pink gold alloy that is unique to Rolex watches and has been used with all their pink gold oyster cases since 2005.

You’ll also find a black matte Cerachrom dial which is a hardened ceramic material that is a tough and highly scratch resistant material that has anticorrosive properties and is impervious to discoloration from exposure to Ultra Violet rays. Perfect for spending your days relaxing on the deck of a luxury yacht.

The dial on the Replica Rolex Yacht-Master 116655 with its cyclops date magnifier could be passed as that of a Submariner if it weren’t for all the Everose gold used. You can find this material used on the rims of the index hour markers, the Rolex logo, and luminous filled hands. You won’t find rose gold on the dial of any watch in the Submariner series (yet?). The combination of black and Everose gold is a real eye-grabber giving this the look of a really luxurious watch.

What’s running inside this stunning watch? The Yacht-Master 40mm runs off an automatic Rolex perpetual movement, the Rolex caliber 3135. This 31 jewel movement beats at 28,800 vph and has a power reserve of about 50 hours.

At a glance, this watch is an impressive piece of eye-candy with a polished case and two-tone rose gold and stainless steel bracelet. The design used vibrant colors from the blue Cerachrom bezel to the rose gold pushers and patented Triplock crown. The white dial is equally full of harmonic colors with blue steel hour, minute and subdial seconds hands and rose gold and red chronograph hands. A rose gold rimmed sub-dial and applied rose gold rimmed index hour markers tie it all together.

A unique feature of the Yachtmaster II is the regatta chronograph and features the world’s first mechanical programmable countdown with a memory. You can accurately sync the watch with the starting sequence of a yacht race.

Unlike most bezels which don’t operate as a component of the movement, the easy-to-use and bi-directional Ring Command bezel on the Yachtmaster II operates in conjunction with the regatta chronograph as an integral component of the movement. This bezel is the method in which you can synchronize the countdown timer to the start times of a race. Each time you press the button you can adjust the timer by one-minute increments for up to a 10-minute countdown timer. When you adjust the rotating bezel back to its default middle position, it resets the chronograph back to its main function.

This COSC certified Swiss chronometer is the self-winding caliber 4161 automatic movement beats at 28,800 vph and is completely manufactured by Rolex. This movement features the Rolex antimagnetic blue Parachrom hairspring. After receiving a COSC certified chronometer certification, the movement the goes through a thorough in-house chronometric testing once installed into a watch case. Once the watch achieves a precision of -2/+2 seconds per day in the case, it gets a Rolex Superlative Chronometer designation. Even with all these mechanical features, the 31 jewel caliber 4161 movement holds its power for 72 hours.

The Master Chronometer VS Superlative Chronometer

Luxury watchmakers are always upping the ante to lead the pack with the most accurate mechanical watches in the world. Find out how these two market leaders do it.

Let’s start with how watches with this title are similar. Simply put, they are both required to be certified chronometers and go through the standard COSC ISO 3159 testing before any further testing is done.

COSC testing involves only the watch movement/caliber itself and for two consecutive weeks, the movements are tested at three different temperatures and 5 different positions.

By the time the movement received its chronometer designation, it has reached an accuracy of -4/+6 seconds per day. Both Rolex and Omega felt that they could work on the post-COSC accuracy and precision.

Replica Rolex watch took the chronometer to the next level with an extra round of testing and fine-tuning.

Once the watch movement is returned to manufacture, Rolex cases the caliber and a series of tests designed to simulate the use of the watch when worn in a “real-life” situation is conducted followed by fine-tuning until the accuracy of -2/+2 is achieved. That is at least twice as accurate as a COSC chronometer!

Once this is accomplished the watch is ready to be shipped out with a new Superlative Chronometer designation.

The first Rolex movement to ever go through Superlative Chronometer testing and get the esteemed Superlative Chronometer designation was the Rolex 3255 movement found in the Rolex Day-Date 40mm.

They had since decided to expand their highly strict ±2 testing to every one of their watches. They had since attached to each watch they sell that meets this standard in accuracy and precision a seal saying “Superlative Certified” on one side and “Rolex SA Geneve” on the other.

OMEGA, eager to rise to the challenge, embarked on a mission to state their dominance in chronometric precision with a new chronometric precision designation known as the Master Chronometer.

The first OMEGA watch that was given the designation of Master Chronometer was the Globemaster which is part of the Omega Constellation series. A testing institute called the Federal Institute of Metrology, also called METAS conducts the testing after the watch received a COSC certification.

METAS labs take the watches and have their movements tested for a number of things in order to reach a minimum precision of 0/+5 seconds per day.

The first of these tests gauges how it reacts to being exposed to magnetic fields of 1.5 Tesla / 15,000 gauss while in two different positions.
Then the caliber is cased and put into a watch and they test how it handles the same fifteen-thousand gauss magnetic fields.
They then expose it to 15,000 gauss for a full 24 hours and test its daily precision for any deviation.
They then look at the average daily accuracy of the watch over a period of 96 hours while alternating positions and environmental changes such as temperature fluctuations. The Power reserve is then examined to ensure it runs at full mast for the projected capacity.
They then look for any deviance of accuracy in any of six different positions.
The watches are then tested again in 6 positions for any chronometric discrepancies in time while the power reserve is between 33% and 100%.
The water-resistance of the watch is tested by immersing the watch in water and increasing the pressure until it reaches the intended depth of water resistance.
