Quite some time ago, I was researching the reason behind why so many 17 jewel movements powered US Collection Omega watches in the 1950s and 60s, when I chanced upon a movement series about which little was written and less was said. And yet, this series, because of the minimal number of pieces produced, meets the criteria for rarity in Omega watches.
I published an essay on these rare models in 2008, and subsequently a small cadre of collectors embarked on a treasure hunt to locate and acquire examples. Treasure hunts by fellow collectors tend on occasions to yield unexpected booty that helps add to the knowledge base, and that has certainly been the case with calibre 560 models……but I get ahead of myself.
Originally, four specific models were identified – three Seamaster DeVilles and an Omegic generic brand – and examples of each of them were featured in the original essay. However, as a result of UK calibre 560 collector Graham Smith’s detective work, another Seamaster powered by the calibre was unearthed! That discovery led to the materialisation of a cache of calibre 560 models not listed on the Omega Vintage Database!
The upshot of this find is that a total of nine models were powered by calibre 560 movements. Only 3000 movements were made and this means that each of the models were effectively ‘Limited Editions’ in everything but name.
