Somewhere is its own, Chanel J12 will return to its origin some day: the boundless ocean, and the powerful waves. Since its birth, J12 has always being regarded the ocean as its design inspiration. This year, in J12’s 10th anniversary, Chanel reaffirmed its orthodox nature of diving watch and launched three new J12 Marine watches.

The case is 38 or 42mm advanced and in atramentous of white. Still ceramic, the atramentous case is bead-blasted for a matte, rather than agleam finish. Though the white adaptation is still done with a bright finish. Going afterwards Blancpain’s 50 Fathoms or IWC’s Aquatimer, the J12 Marine has a azure clear over the alternating diver’s bezel. I adulation that look, but it is not for everyone. The case superior is actual good, with the watch getting solid and comfortable. Perhaps a bit baby for humans who adopt 44mm additional watches, the 42mm advanced adaptation is still not too bad. The atramentous with atramentous bezel adaptation is alone accessible in 42mm.

The dial is all Rolex Submariner homage in bubbly way, but with an Arabic numeral 12, at 12 o’clock. Chanel uses a fat arrow for the hour hand, and a blue baton hand for the minutes – that is matched to the seconds hand. The hour markers are all applied and raised up making for a great look against the simple looking dial. There is tons of lume all over the face as well. You can see the cross hair style lines in the middle of the watch face, just like on the standard J12 model.

1. What is a watch crystal?
A watch crystal is a transparent cover that protects the watch face. Note that, coincidently, the word “crystal” is also used to denote the tiny piece of quartz that serves as an oscillator in a quartz watch. These two types of crystals have nothing to do with each other. The latter is usually called a “quartz crystal” to prevent confusion.

2. What are watch crystals made of?
They can be made of any of three materials: 1- plexiglass (a clear, lightweight type of plastic), 2- ordinary glass – like that used for windows, and usually referred to in the watch business as “mineral glass” or 3- synthetic sapphire (see question 4). Some crystals are made of both mineral and sapphire glass. Seiko, for example, makes some watches with crystals made of mineral glass covered with a layer of synthetic sapphire. Seiko calls this composite material “Sapphlex”.

3. What are the advantages and disadvantages of each materials?
Plexiglass, as you would expect, is the least expensive. It is also the least likely to shatter and the most likely to become scratched. Mineral glass, even though it has been hardened by a tempering process, is more likely to break than plexiglass. But it is also more scratch-resistant than that material. Synthetic sapphire is the most expensive glass crystal material and the most scratch resistant. Because it is so hard, it is also brittle, and shatters more easily than mineral glass or plexiglass.

4. What exactly is synthetic sapphire?
It is a very hard, transparent material made of crystallizing aluminum oxide at very high temperatures. Chemically, synthetic sapphire is the same as the natural sapphire used in jewelry, but without the coloring agents that give the gemstone its various hues.

When it is heated, the synthetic sapphire forms round masses that are sliced into pieces with diamond-coated saws. These disks are then ground and polished into watch crystals. (One reason sapphire crystals are relatively expensive is that the tools required to make them are costly.)

Sapphire (whether natural or synthetic) is one of the hardest substances on earth. It measures 9 on the Mohs scale, which is a system for rating the relative hardness of various materials. (Diamond measures 10, the highest rating.) Watch crystals made of synthetic sapphire are often marketed as “scratch resistant”, meaning they are very difficult – but not impossible – to scratch. Diamond can scratch them; so can man-made materials that incorporate silicon carbide, with, with a Mohs rating of between 9 and 10, is, like diamond, harder than sapphire. These materials are sometimes used to make simulated-stone surfaces for furniture or walls. The watch wearer should note that accidentally scraping a sapphire crystal against such a surface could cause a scratch.

5. Can you tell if a crystal is made of sapphire by looking at it?
No. Mineral glass and sapphire generally look the same. A surefire way to tell them apart (albeit an often impractical one) is with a scratch test, says Johann Jorgo, technical director at Baume & Mercier Inc. New York. A stainless steel knife or screwdriver will scratch a mineral-glass crystal but not a sapphire one.

The bargain will accessible on 9 May in Geneva at the Hotel Beau Rivage, and the Big Pilot’s Watch Copy Antoine de Saint Exupéry in platinum will be auctioned calm with a appropriate copy of the Saint Exupéry adventures “L’archange et l’é crivain” by Nathalie Des Vallières at a assets amount of CHF 50,000.

The absolute gain from the bargain of this alarm will be donated by IWC Schaffhausen to the French organisation “Enfants du Monde/Droits de l’Homme” (EMDH), which works common to assure accouchement and their rights. In particular, IWC supports projects in Madagascar, area EMDH has been alive calm with bounded ally back 1994 to advice disadvantaged children.
