14060m COSC started when?????

I think I remember them starting in the Z's. Is that right? Some Z's were two liners and some Z's were four liners....

Thanks guys.

Early 2007, non COSC certified, late 2007/08 COSC certified. Same exact movement, pure marketing.

Yes sir, for modern. Don't forget about the 5512's for vintage.

Cool! Much appreciated. There is a guy on CL claiming to have an older watch with 4 lines, but it isn't a 5512. fake.
