Greubel Forsey GMT Earth Titanium

Greubel Forsey luxury During the Geneva Watch Days 2021, Greubel Forsey presents the third and final interpretation of its GMT Earth. Crafted from titanium, this deep black version is limited to 11 pieces.

Greubel Forsey’s GMT Earth is an extraordinary watch that, for the first time, allows you to see the world at a glance.

This technological feat first appeared in 2011. At the time of the first “GMT”, the Earth was not yet fully manifested. Seven years later, the design for Earth is finally complete: visible from every angle in the new sapphire niche, it appears to be floating in space. On the front and back, a laser-engraved globe shows the world time in a quick and easy-to-read format.

The first version of GMT Earth replica was platinum. The second is platinum. Now, this watch comes with a new titanium case. The titanium GMT Earth will be limited to 11 pieces, three times less than the original. Weighing just 117 grams, the strap is two-thirds lighter. The case is a little over a third lighter.

Titanium is used not only for the entire case, but also for the bridges, GMT pusher, crown and folding clasp, the latter two being the parts most vulnerable to shocks and scratches.

To complement the light and matte shades of titanium, Greubel Forsey opted for a black dial. It works with speckled baseplates and all matte bridges with straight sides, polished bevels and countersunk holes. This treatment is also used on the all-black natural rubber strap, whose inner surface is engraved with the basic values ​​of Greubel Forsey and is visible on the bezel.

GMT Earth displays four key pieces of information on its dial side. The first is the eccentric hour, minute and second display. The first two large skeleton hands are decorated with Super-LumiNova luminous coating, and there is a small seconds on the sapphire disc at 3 o’clock. Discount watches

On the left is the GMT hour-marker, whose red hands stand out effortlessly against the hand-engraved lacquered black-gold disc. The third, located opposite the crown, is the power reserve, whose design follows the same process: black engraved with gold, filled with lacquer and covered by silver-polished steel hands.

Finally, between 7 and 9 o’clock, the earth occupies the most space, and completes a full rotation in 24 hours. An engraved sapphire ring around the equator acts as a day/night indicator, allowing you to instantly see which hemisphere is during the day and which is at night.

The last window on the side of the strap opens to show the equator. Thanks to this, the Earth can really be seen from every angle. quality replica watch

Finally, on the bottom cover side, the world time display indicator completes the design. The 24 time zones represent UTC for the 24 major cities – those that observe daylight saving time on a white background.

GMT Earth features Greubel Forsey’s third invention, the 24-second tourbillon, which uses rapid rotation and setting an angle to solve gravity-related positioning problems that are critical to the operation of the oscillator. The 25° angle and rapid rotation of the tourbillon cage significantly improve the timekeeping performance of systems containing only one tourbillon, especially those in a fixed position.

Ulysse Nardin Black Sea chronograph hands-on

If you inadvertently tell me that rubber-coated watches can make luxury watches, I will never believe you. Then it started to happen, and high-end brands started experimenting with vulcanized rubber coatings on watches. It starts with the bezel, crown and buttons. Then brands like Ulysse Nardin said, “Go ahead, let’s coat the whole damn thing with rubber.” This is the source of fragments like the original Black Sea. Since then, Ulysse Nardin has launched a series of rubber-coated watches based on Maxi Marine. There is a blue model, and some are decorated with various styles of decorative details, such as the model with a gold bezel unique to the Boca Raton boutique in Florida. This is the first chronograph version with a rubber-covered design.

This watch is called the Black Sea Chronograph. As a diver, it is water-resistant to 200 meters and has a rotating diver’s bezel. Although few people actually dive underwater with such a watch, the dial does represent its practical theme with eye-catching hands and hour indicators. One thing that is surprising seems to be the hollow hands. Recently, I noticed a great personal dislike for the skeleton hand. Mainly because they are usually of no use other than making it more difficult to read the dial. Designers use them for two reasons. First, for practical reasons, the dial below the pointer is more clearly visible. This makes sense, and is usually a trade-off between legibility and being able to view dialed information for more time. The second reason is purely for design. This is what I hate. This is when the designer thinks that the hollowed-out hand looks cool in CAD drawings and computer rendering. They may not care about reducing the practical level of an actual watch by a few steps-they don’t know that the materials used to make the dial and hands greatly affect how it looks in real life compared to computer images. This is especially bad when you need to check that there is nothing under the hands on the dial. Stay away from those watches. In this case, Athens Watch took a more practical approach. The hands are hollowed out to allow more time to view the chronograph subdial. This is because the hands are really fat. Therefore, when they are hollowed out, the tip of the fat lumen coating is large enough to be easy to see.

The Black Sea Chronograph case is 45.8 mm wide, but due to the thick bezel, it is smaller than it looks. You can see that the dial has a sand-like texture and splashes of red and blue on the surface. Although the name of the watch is Black Sea Chronograph, fake Ulysse Nardin reminds you that this is of course part of its Ocean Diver collection, right on the dial as part of the unique-looking auxiliary seconds counter. The side of the case is a steel plate with the serial number of the watch on it-this is not a limited edition.

How does vulcanized rubber feel on steel? Okay, of course the rubber sticks to the shell nicely. It is glued to it, so it is not like a steel shell wearing a rubber jacket. You will think it should wear well, but the correct shot may end up tearing some of the rubber. I want to know how often this happens. Vulcanized rubber is quite durable, especially in this case, it does not need to be bent at all. My understanding is that it should look good for at least a few decades. I don’t know the vulcanized rubber watches from 30 to 40 years ago-so I really don’t know how they are supported.

A black rubber strap is attached to the black case. In the true Marine Diver style, the rubber strap has two black ceramic pieces close to the case. These are engraved with the Athens watch logo. There is a sapphire exhibit back cover on the back of the case, which helps to break the consistent appearance of black rubber. Inside the watch is a caliber UN-35 automatic chronograph movement, which is a basic Swiss ETA. Even the crown and buttons are made of vulcanized rubber to complete the theme. In general, this is a unique sports chronograph watch. I think it looks more interesting when handled in person than in marketing pictures. Finally, I have to ironically comment on the Ulysse Nardin’s press release, which is that “The Black Sea Chronograph is suitable for those who have a few hours before returning to the sea.” You can make a joke about this strange comment about ocean addiction.
