Seiko’s 5 Sport series – like this full serviced 1968 Seiko 6106-8180 DX automatic here – were popular and quite reminiscent of the late 1960’s and 1970’s chic.


Seiko debuted its 6106 dive watches in 1967 as its first “Sport Diver.”   Notably, the 6106 was Seiko's first dive diver, that is.  The Seiko 6106 series - just like its 6119 little brother subsequent - was a line of 70-meter diver watches; the line was aimed at “light” water sports that gained in widespread popularity during the late 1960’s and 1970’s (hence the 70-meter dive rating); however, these dive watches did not feature diving bezels.

As noted by Worn&Wound, Seiko’s marketing ads boasted about the 6106’s diving capability, that was “Proof," all the way down to a whopping 229 feet (!); other ads made the line seem like the choice for surfers.  Granted this makes for some shallow diving, but not in the era these debuted.  Regardless, it was a popular offering and affordable. 


On to 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.  Couple this with very little writing on the dial and raised applied hour indices, and you have a dial that’s purposeful and sparse.  


Even today, Seiko's 5 Sports line continues to win plaudits - as noted recently in GQ Magazine, "Regardless of where a budding collector might be headed, the first question they all have is the same: Where do I start?"


"My answer is the Seiko 5 Sports line.  These watches check all the boxes: They’re affordable, distinctive, and, despite costing a fraction of what most mechanical sports watches do, are built to last.  The famed Japanese watchmaker launched the 5 Sports line in 1968, and revamped it in 2019 when it released prices that seem to be missing a zero."


"For the aspiring collector who has never owned a watch, the attractive price point of a 5 Sports may be all the convincing one needs.  And for the burgeoning horologist who already owns a timepiece or two, these watches come with the history, the quality, the sophisticated design, and the functionality that make them every bit as essential as any Swiss brand to a well-rounded collection."


Seiko made literally hundreds of Sports diver variations during this time period, with the Japanese manufactures’ Suwa and Dani factory seemingly in competition with one another to see which could devise the most compelling models.


This 6106 comes on a stainless-steel vintage bracelet, and with nylon strap, rugged travel case, and spring bar tool.
