you may find the movement is a 562.
the 560's were mainly made for the US importer Norman Morris and is a 562 with 17 jewels instead of 24 that the 562 has. all due to the US import restrictions and charges for 'jewels'.
most swiss made models have the 562, whilst the US models have the 560.
having said that, my steel cased swiss made model has a 560 in it so nothing is set in stone.
i would be very interested to know what actually is inside it as it would help us know more about the usage of the 3000 560 calibres made. a very small number for so many models.
enjoy it Andreas and dont forget me in the future

Cal. 562 most likely then

Hello Graham, according to your information the cal. 562 is most probable as the watch was sold in Italy. Art presumed a cal. 560, but he will mainly see vintage Omegas that were sold in the US. I will remember you if I should get a sight of the movement ...
