The OG Seiko 6105-8000

The Turtle was released in 1967/1968, more specifically the 6105-8000. Rated at 150 meters, this new Seiko case introduced the “anti snag” crown located down by the four o’clock. The 6105-8000 came before the famous “Willard” ref.6105-8110.

The 8000/8009 versions have “Waterproof” instead of “Water Resist”, on the caseback and dials. The 6105-8000 was also the last Seiko diver to have the signed “SEIKO” crown for this line of sports watches, this signed crown is not a screw down crown as well. This watch came with a hardlex for the first time on a 150 meter diver in Seiko’s line up. Another difference from the later Seiko divers is the small detail in case shape. The earlier 8000 and 8009 featured symmetrical cushion cases unlike the divers that came after the 6105-8110/8119 which had asymmetrical cases.

Inside the 6105-8000 is a 6105 movement running at 21,600 bph and containing 17 jewels. Quickset date is a feature but no hack ability with this movement. The 6105-8009 received an upgraded 6105B movement which added hacking.

The dial is a deep black, all hour indices have applied silver surrounding them, and an applied Seiko logo to top off this great robust dial. The second hand is what helps define the 6105 family. The spectacular arrowhead shape showing lume at the end and a red contrast right behind it. The 8000 wears nicely with a 41mm diameter case and 12.5mm thickness

Signed Crwon

Seiko has came out with multiple re-editions of the Captain Willard and 6105-8000. The SPB151 being the closest to the 8000 with the 42mm case and black dial that wears much closer. SPB153 with a green dial is a great option.

With not many knowing about the 6105-8000, it is the time to pick them up before they become extra difficult to find as collectors start seeking them out.
