There's an excellent essay on the Calibre 565's movement
here (the article is about 551 which is the non-date chronometer version of the 565 but its the same movement just without the date wheel, it'll be explained in the essay) written by Desmond (
@mondodec) of the Constellation Collector blog, well worth a read to get an idea of the movement that your watch contains.
