"Edouard Heuer came up with the oscillating pinion in 1887," other interesting items to read from the link that wilfreb posted, maybe seiko copied some of Heuer's older material ?
the Seiko 6S37 movement is 40 jewels and the tag 1887 is 39 jewel movement,the 1887 has 320 working parts and the Seiko 6s37 has 290 parts, other items are different also, in a watch case you can only have so many gears, wheels and springs before you run out of space, a watch keeps time so it is common for movements to look similar, but be different.
Strickly speaking, it has not yet happened. The ebauche (base) and the rest of the watch is all made in Switzerland....And in Switzerland, no big company ever has produced mechanical watches using japanese ebauches... until today.

Ciao Enrico, always a pleasure to share the evening with other watch lovers. And sincerely apologize if ever I created some confusion initially as it was never meant to be. Remember that in 1969 we did not do it alone either but with Breitling, Buren, Hamilton and Dubois-Depraz. When you want to produce high quality in significant volumes, capitalizing rather than re-inventing the wheel can be a smart idea especially if the outcome is a beautiful, reliable, performant, evolutive and versatile movement. And Caliber 1887 is that. For breakthrough it's another story,......but for everyone apparently, except maybe with TAG Heuer, but then through the V4 and unfortunately with.....only 150 masterpieces produced as we lack capacity for such a daring re-invention of a mechanical movement.Despite all the content of the previous post, I am honored to see two facts :
1- Our Forum reaching TAG Heuer HQs; and
2- Mr. Babin honorably posting his words here.
Thank you very much for the post. I am sure this is very appreciated by all members and fans.
