561 is the non quickset date movement @reziprozi, these were used before the 564 as far as I understand it.
On the dial, I thought that the solid gold watches, with solid gold bracelets also had solid gold dials - if it's not marked as OM, I don't think it's a gold dial.
I think there are a few solid gold dials without OM. What do you think about the dial and the combination with the Cal.561 ?
I don't really have a view I'm afraid... more research required... which I'll leave to you if you're looking to buy @reziprozi 😉
Thank you my friend. I am searching..and Desmond‘s Blog seems to be a great info source. Otherwise I see some C Cases with those hands had been sold. But Desmond‘s Blog never mentioned such a combination.

A very similar / same one

Here is another C-Case , not mine but I it is for sale. What do you think about it? I have a similar one but this has different hands and no „OM“ at the dial. I don’t know if the dial is solid gold. But the warch is in 750 Gold (about 128 Grams and never polished). Unfortunately without papers\box.
It has a 561 movement. Is that right with that case/hands?
Thank you for helping!!
It is my understanding that the OM dial is referred to as a Sigma dial. A Sigma dial has gold hands and indexes. There is an interesting article in Hodinkee .

-> I think this is a legit combination of the 1970‘s C Cased Constellations.

The seller guaranteed that the dial is solid gold. So I come to the conclusion that there is no OM mark if the hands are not gold. therefore you have to recognize gold through the glass 😀

Also a gold dial without „OM“
