Seiko debuted its 6106 dive watches – like this deep blue-dialed variant from mid-1970 – in 1967 as its first “Sport Diver.”  Notably, the 6106 was Seiko's first dive watch - sport diver, that is (more on that below).

The Seiko 6106-8589 is beautiful classic vintage Seiko for several good reasons, starting with the well-spaced dial, which renders the bezeled day/date window unobtrusive. On to one of the best features of the 6106 – the dial. These dials, regardless of variant color, sparkle in the light and were finished better than many of the Swiss watches from the same period, and this amazing deep blue dial is likely the best example of all the 6106 variants. Couple this with very little writing on the dial, and you have a dial that’s purposeful and sparse, finished with Seiko’s famous Suwa logo. Once you add the case-colored bi-directional bezel, which flows well into the radial polished case, you have a nicely elegant and simplistic dive watch.

As noted by Worn&Wound, Seiko’s marketing ads boasted about the 6106’s diving capability, that was “Proof," all the way down to 229 feet! Other ads made it seem like "the choice" for surfers. Granted this makes for some shallow diving, but not at that time. Regardless, it was a popular offering and affordable, but not cheap for the time period, at a price of $75.This Seiko Sport Diver automatic comes with a leather rally strap, NATO strap, spring bar tool, and Pelican travel case.
