The Reference 7923 Submariner is perhaps the most unknown reference in the Tudor Submariner collection and only few have ever seen one. Until they were considered prototypes or “”. Even during the early stage of listing on ebay, some collectors even considered it fake!
H finds show them clearly described in Rolex/Tudor service catalogues, and grouped with the 7922 and Rolex 6536/1. It has a manual wind movement. Cal. 1156-1188 which is unique this model. Lesson learnt is with vintage Rolex & Tudor one can never say never!
