The plastic spacer and basicness of the movement would lead me to believe it's a basic 21J movement. But I can't see any manufacturers symbols near the balance wheel.
I would also guess its a 21j of some sort, probably made by TY based upon the way the balance / plates look, probably in the 28xx series where xx is the unknown last two digits
I have the same movement in my breitling chrono. It is a 21j movement. I need to find a replacement for mine. And i need help finding it. Can anyone help? I have a website that sells movements, but i dont have the slightest bit of an idea how the find the one i need. Here is a link if you guys can take a look and then let me know. http://www.stsupplyonline.com

Oh but mine is a day/date at 3oclock
