The Credor brand was created in 1974 yet was released as a collection of models and not necessarily its own brand. In the early 1970’s Seiko produced a number of high end models that were fitted with precious metal cases and bracelets and seemed to be retrofitted versions from steel. Others however were uniquely designed and are quite rare and many were originally sold only in the Japanese market through catalogs. These watches, and the catalogs were only available at select Seiko dealers and the brand did not really show evidence of pushing forward until 1975 and beyond when the name became recognized as Crêt D'or and the brand was beginning to be built. This continued through the 1970's and 1980s before the name eventually became Credor.
