Was wondering if the 120 omega seamster 166.073 watch came originally with dark blue or black dial? I acquired one off ebay and was advertised with a "matte black " dial. any info from would be appreciated. thank you all

 

I think they came both ways.

 

Would you happen to know if the date wheel was white numbers on black wheel if black dialed or could it have been lack numbers on white dial as well please? thank you
