SIHH 2013 Preview: A. Lange & Sohne Grand Lange 1 "Lumen"sharetweetshareA breitling gmt . Lange & Sohne has revealed the primary of their new timepieces being launched at January's SIHH watch fair in Geneva: the Grand Lange 1 Lumen. A small edition of 100 pieces, the watch features two firsts for your German luxury brand: a luminous outsize date as well as a partially transparent dial.The watch also comes in a platinum case and it has a dial with sections crafted from semi-transparent sapphire crystal; just the outer ring along with the surfaces on the subdials (one all day and minutes, the other for small seconds) are made of blackened silver. The sapphire areas reveal the disk mechanism in the outsize date within the dial. The large date, watches a hallmark of the Lange 1 group of replica watches, may be the first that  glows at night, with the time and the electricity reserve display. The Lange outsize date was inspired by the Five-Minute Clock in Dresden's Semper Opera House, in which brand namesake Ferdinand A. Lange contributed his an understanding of 1841. This way from the clock, the date mechanism of an Lange watch maximizes the date display by way of two separate elements: the ring-shaped units disk with all the numerals 0 to 9 switches every day, till the transition from the 31st towards the 1st, where it stands still for a day. The "tens" cross, with all the numerals 1 to 3 plus a white blank space, advances by only 1 increment every Ten days. Gets hotter displays these, the tens cross advances towards the blank space after only 48 hrs. The irregular switching sequence is controlled by two program wheels having a precisely calculated toothing pattern. To fix the technical challenge of ensuring maximum luminosity to the date display, even right after the daily switching operation, Lange's developers coated the tens cross with a white luminous compound before imprinting the black numerals, then used transparent glass imprinted with black numerals for that units disk, which rotates when in front of a luminous background. The sapphire parts of the dial are given its own coating that blocks a lot of the visible spectrum associated with however, not the invisible ultraviolet light spectrum, which means that UV radiation can traverse to your luminous surfaces with the outsize date unhindered. And this the helps make the date platform, using its manually applied perlage, normally seen only from the watch-maker throughout the assembly process, best rolex visible for the watch's owner.  The small, overlapping circular graining, produced by hand utilizing a rotating abrasive peg, is normally concealed underneath the dial.The movement, Lange's manufacture Caliber L095.2, is visible through the sapphire caseback. A. Lange & Sohne started using this new, manually wound caliber with the Grand Lange 1 only this year. The omission of a second mainspring barrel plus a new arrangement on the parts reduced the overall height with the caliber without compromising some of the power reserve, and allowed to get a dial arrangement during which no off-center subdials for many hours and minutes, small seconds and power reserve need overlap 1 another or outsize date display.
