·Heuer made first wrist chronograph in 1914. So it’s an anniversary model for 100th. But it’s only sold on Japan and 200 pieces.
Not sure why the 2014 100th anniversary watch should be unique for the Japan market. Perhaps it's because Longines is widely credited with having released the wristwatch chronograph first in 1913 and Breitling is credited with the first wristwatch chronograph with separate pushers in 1915.
