What is the significance of the term "calibre" as in calibre 11, I own a TAG 6000 Calibre 11 eg.
The 'Calibre' is the movement. Calibre 11 was the first automatic chronograph, developed in a secret project by Heuer, Breitling, and Büren.
Check these posts to learn more about the different movements.
If you dont mind me join the conversation, i always read and wonder which one is first automatic chronograph between calibre11 and elprimero.
But this is my summary after one article after another: (Please correct me if i am wrong)
Elprimero was first introduced quietly in the late 1968 but only available ready for consumer in the late 1969.
Calibre was launched for public on 3rd March 1969. Which made it the world first automatic chronograph (or chronomatic as they term it).
Elprimero itself means "the first". Everytime i go to the zenith store in my area, the sales always told me its the first automatic chronograph hence the name. Maybe they are trained to do so but i dont know much about that.
As far as my opinion goes. Maybe Elprimero was developed first. But the one that win the race was Calibre11.
What do you guys think ? Is there any point i am missing ?
This is from the 1st link I posted:
El Primero was announced first, but wasn't ready for production for some time after that. The Calibre 11 was production ready when announced and went into watches straightaway. Jack Heuer covers this in his book.
Separate names with a comma.
