My thoughts are that this is an International model (not sold in the USA), based on the leading 1- in the serial number and the lack of an import code on the 1966 movement, as well as it states International on the caseback.
I've checked through or international catalogs and I am unable to find a model match. Quite a stunning watch with the 18K case.
