Thoughts on the cal. 1320 movement?

My understanding is that it was based on a GP movement, but I'd be interested in more information.

Thank you in advance.

version (time only) and based on a GP movement. The quartz models represented less than 10% of the overall Overseas production.

I'll see if I can come up with more technical data if you're interested

Alex, I'm sorry but I've made an error...

it is actually the cal. 1312 (automatic) which is of interest to me.

Thank you.
