In 2001 Ulysse Nardin made an important breakthrough with its extraordinary watch the "Freak" which used a unique, very high-tech dual cheap watches wheel escapement using silicon wheels. This pioneering move ushered in the start of the silicon revolution in watchmaking.Since then many other watchmakers have used silicon. Omega found it to be complimentary to their use of the co-axial escapement and now all co-axial calibres are equipped with silicon balance springs. Patek Phillipe having been involved in the use and development of silicon in watches since 2005, filed a patent for the first silicon escape wheel for a Swiss lever escapement. And in LED watch what some considered a controversial move, in 2011 they announced that silicon balance wheels will gradually be added to all Patek Phillipe calibres.Four Breguet calibers had previously incorporated silicon and in 2006 they introduced their first watch with a flat silicon balance spring and escapement. More recently in 2013, Roger Dubuis released their Excalibur Quatuor which was the world’s first phablet silicon watch incorporating four sprung balances. Richard Mille exploiting silicon's qualities of hardness, resistance to wear, temperature and corrosion as well as its lightness, used silicon nitride for the bezel and case of the RM011.There are some reservations expressed about the use of this new material; aesthetic considerations for instance, silicon doesn't offer you the same opportunities for movement decoration that traditional metals do. “These HD media player parts must be used as machined,” says Stephen Forsey, which “excludes any hand-finishing - an integral part of high-end watchmaking.”There is also the issue of replacement parts for watches using silicon. Since it's a lot more difficult refashioning parts from silicon than metal, such components “not only cannot be redone if you do not have the technology and exact plans, but as the technology will evolve, the parts made today will probably not be reproducible in the future." says Maximillian Busser regarding such concerns. Another issue is that some watch makers say that silicon, while hard, is possibly too brittle to last as long as metal in the long term. They plea that it is android tablet too early to prove or disprove this, but even Ulysse Nardin who innovated with silicon has been pushing forward with a form of diamond coated silicon (that they call Diamonsil). This hardened version of silicon may counteract potential durability concerns making it a choice mechanical watch making component in the future assuming that they can be reproduced easily.But in the end doesn't silicon bring watchmakers closer to their dream of a mechanical watch that runs for eternity wrist watch for kids without the need for maintenance and ideally extreme precision? Just seeing how embraced it has become is a clear sign of just how important it is.Top 10 Technically Important Mechanical Wrist Watches watch talkSoon after the original Milgauss in 1955, IWC countered with their Ingenieur model which used the inner shielding approach from their earlier Pilot's watch, this was the forerunner to their Ingenieur 500,000 a/m released in 1989 which had over six times greater resistance to magnetic fields than the Milgauss. 745TDBanty 130723

If you're hoping to beef up your storage space, know that you'll be limited to a 32GB card. The Slate 7 doesn't pack a whole bunch of bells and android tablet whistles -- there's no GPS or Bluetooth 3.0 or 4.0. Out of the box, it comes with Bluetooth 2.1 with EDR, 802.11b/g/n and an accelerometer. The latter proved to be reasonably responsive, though we did notice the occasional stutter as the display shifted orientation.Using the Slate 7 is an intensely vertical experience. The tablet is built according to a slightly narrower-than-normal form factor, and due to an unusual aspect ratio, everything is just... off enough to be noticeable. The 1,024 x 600 screen isn't great to begin with, especially when compared to the Nexus 7's 1,280 x 800 IPS display (currently $30 more, but a much better buy). At 169 pixels per inch, that resolution LED watch would have worked on a slightly less rectangular form-factor (a 5.86-inch display would have worked with the tablet's 4.44-inch width). Considering that the Slate 7 comes with stock Android 4.1.1, the flatness of the UI makes the stretch especially obvious. Even round icons are more oval than circle.Again, for a budget tablet, we weren't anticipating much from the display, but the Slate failed to live up to even our modest expectations. The colors aren't particularly vibrant to begin with, but any viewing angle other than straight-on caused them to be significantly washed out. The technology HP used for oblique viewing angles -- "Fringe Field Switching" as opposed to IPS -- does little for the LCD display when the device is angled even a little bit away from the viewer.When it Mini Speaker comes to sound quality, HP is putting all its eggs in one Beats Audio-branded basket -- as it's done with many of its products. From the Beats logo on the back of the tablet, to the Beats-specific tab on the settings menu, HP is aggressively pushing the relationship at consumers.The dual speakers located on the bottom of the tablet are adequate in the truest sense of the word, which is to say: they work. Because they're so close together, there's no real stereo sound despite there being two of them. Do they sound like $170 speakers? Not really. Played at reasonably loud volumes, the audio is strained and tinny, as is the case with many a mobile device. With the Beats sport watches Audio feature toggled on, vocals on most songs had a noticeable echo not present when it was turned off.When it comes to headset use, we must admit there's a certain level of cognitive dissonance required to use -- or even worse, acquire -- a pair of headphones more expensive than the device you intend to couple them with. But if you're a Beats fanatic (we know you're out there), then perhaps the Slate 7 will tickle your fancy. For those of you who aren't immediately charmed by the promise of Beats Audio's potential (and so far, we see no reason why you should be), the actual feature is pretty lackluster.Beats Audio can be toggled on or off, but it's basically nothing more than a jazzed-up EQ setting. 745TDBanty 130709
