TAG Heuer caliber 1969
In 2009, TAG Heuer launched the caliber 1887, an in-house made automatic chronograph movement. At launch, TAG Heuer dubbed it a Swiss in-house movement but because the actual design was based on Japanese intellectual property rights which TAG Heuer had purchased from Seiko, the international watch trade press called out this fact. It went viral, and so the company eventually made a public correction, admitting the movement’s design origin was in fact Japanese, not Swiss. With that said, only the design came from Seiko — the oldest and, arguably the best Japanese mechanical watchmaker.
