I think parallel....
Definitely the non-chronometer/chronometer ref 8444 was parallel.
Of the 5600 ref 8444 a unknown number was COSC certified.
I don't know the production number of the ref 8445 and I don't know if it existed in non-chronometer, but I suspect it did.
Thank you, my friend.
Hope this clarifies it a bit...
