This SEIKO reference 6139-8102 from the late 1960’s is a very good looking and uncommon vintage chronograph. The 39mm. stainless steel case and original bracelet display fine overall condition for the age. The striking black dial is the hardest and most desirable to find among the range of colours available in this model. The polished bezel frames the extremely attractive original black dial with original handset. The original crown is present. The day of the week wheel can be set to either English or Spanish. The fine automatic Seiko, Japan – calibre 6139B, 17 jewel movement was just cleaned and is accurate. This really is a great looking and highly collectible vintage SEIKO.
