Tag Heuer achieves a milestone this year. The brand famed for its precision sports watches and chronographs celebrates the 20th anniversary of its popular Link series. The collection, one of the brand's biggest sellers in the company's 147-year history, has caught the eye of a host of sports stars, all happy to lend their names to the line. Celebrity endorsements have come from the likes of golfing giant Tiger Woods, tennis superstar Boris Becker and athlete Marion Jones, among others. To mark the anniversary, Tag Heuer introduced a whole new line of Link watches for men at the Basel fair. All the watches contain a unique new movement that was developed in-house. The Calibre S adds functions while maintaining an easy-to-read dial, something not all chronographs succeed in doing (too often a single watch face is crowded with multiple function counters). The Calibre S ushers in a second generation of movements, bringing logic and elegance to displays of time and data. According to the brand, the Calibre S is a breakthrough in Swiss watchmaking, superseding quartz and mechanical chronographs by combining the best of both technologies. In the brand's own words, the Calibre S is to chronographs what hybrid engines have been to cars that 'combine the advantages of electricity and gasoline'. The movement comprises 230 parts and five 'high-performance' bi-directional engines capable of twice the torque, or rotation, of conventional watches. The dial on all the models is streamlined for easy reading. The Link Calibre S 5 day-Date displays nothing more than the time, day of week (in a wide window at the top of the dial) and date (in a small window at the bottom of the dial). The Link Calibre 16 Automatic Chronograph Tachymetre and the Link Calibre S Chronograph are for racing enthusiasts, or those who simply love a dial that hints at the dashboard of a car. The former has a tachometer scale on a fixed bezel and comes with either a black, silver, anthracite or blue dial. The Link Calibre S Chronograph shows the time and the chronograph display central hour, minute and second hands. In the watch mode a perpetual retrograde date is displayed on both sub counters; in the chrono mode the indication of the 1/100th of a second is displayed on the counters. A push-button crown makes the switch from watch to chrono mode. The watch has a fixed bezel with a tachymetre scale. The ergonomic design of the case and bracelet is faithful to the brand's penchant for avant-garde design. The bracelet is made from Link's signature 'S-shaped' links. Avant-garde as part of timepiece's DNA Technology inspired by the avant-garde, technology that determines function, function spurring design - those are the elements that drive the Tag Heuer motor of innovation. At this year's BaselWorld, the brand unveiled a futuristic booth whose design embodies the brand's vision. Called Tag Heuer Skin, the two-storey construction had a 47-tonne steel frame, a spiralling eight tonne-carapace of aluminium triangles suspended on a membrane of 3,000 points of light. Tag Heuer president and chief executive Jean-Christophe Babin said: 'Its daring aesthetics project it into the 21st century as a living testimony of architectural avant-garde, but it is above all a statement of Tag Heuer's commitment to the fusion of design and technology, mirroring the unique DNA and identity of Tag Heuer timepieces.' Mr Babin said the booth's cutting-edge design embodied the tension and elegance of the prestigious sports brand, with strong references to the Link series.
