Before I start listing the below, note that the naming of the reference (including numbers in the suffix) is taken from the Certificate of Origin, or if not available, then the website where promoted. As such, there may be errors in the naming – please let me know if you catch any.
I lead with the year of manufacture and movement/case number if known. Below the sold piece I include any comments on the dial that are included in the description, beyond that it is black and non-diamond marks.
