Having had a listen it's hard to say what the noise could be, it could simply be a little more amplified through the movement, it could be old lubrication starting to dry a little and a service, clean and fresh oil could resolve it, but i'd suggest it's nothing to worry over if you're getting accuracy to within 3 seconds a day currently.

Just googled dial washer and the first part is definitely a dial washer - not sure if I need it though.
I will struggle to photo the other part it is so small - I am of out now will have a go later today. It is only about .5mm thick. I was wondering if it is some sort of strap to secure the movement in place.
