The New Tag Heuer Caliber 1887 Movement

in Tag Heuer | Sunday, December 13. 2009

To commemorate 150th anniversary of the brand, TAG Heuer has unveiled the in-house chronograph Caliber 1887 movement. This new movement, which took almost four years and 20 million Swiss Francs to complete is comprised of a multitude of individual parts and incorporates a conventional column wheel system. The number of the calibre was chosen to signify the year when the watchmaker invented an oscillating pinion, a groundbreaking development for chronograph mechanisms. The caliber 1887 is an automatic chronograph movement which is equipped with a mainspring barrel, which is recharged through a skeletonized centrally positioned rotor. When it has been fully-wound the mechanism has a power reserve of about 40-50 hours. The glucydur balance wheel beats at the rate of 28,800 vibrations per hour. The total dimensions for the Tag Heuer Caliber 1887 movement are 7.1mm high by 29.3mm in diameter.
