Seiko debuted its 6106 dive watches – like this new-old stock Japanese Domestic Martet (JDM)-only 1969 deep blue-dialed 6106 (and no one does blue dials better than Seiko), which comes with its original bracelet clasp/caseback stickers, price tag, and instructions – in 1967 as its first “Sport Diver.”  The Seiko 6106 is classic vintage Seiko for several good reasons, but onto one of the best features of the 6106 – the dial.


These dials, regardless of color, sparkle in the light and were finished better than many of the Swiss watches from the same period.  This is coupled with little writing on the dial, rendering a dial that’s purposeful and sparse, finished with Seiko’s famous Suwa logo. 


As noted by Worn&Wound, Seiko’s marketing ads boasted about the 6106’s diving capability, that was “[Water]Proof," all the way down to 229 feet!  Other ads made it seem like the choice for surfers.  Either way, it was a popular offering and the affordable, but not cheap at the time, price of $75.

This Seiko Sport Diver comes with its original stainless-steel bracelet, nylon NATO strap, spring bar tool, and Pelican travel case.
