Seiko's Speed Timer roster defines great vintage racing chronographs, and as they were only produced for the Japanese market, owning one can be a bit of a challenge. With a 21 jewel version of the venerable 6139, these examples were definitely a step up from their export counterparts, and boasted a few other distinct features as well. This 7020 from June of '71 sports a deeply set matte black dial with a split, bi-color sub register in black and a vibrant blue. The "Speed Timer" logo sits prominently mid dial opposite the blacked out day/date frame. The minute track is trimmed in “Speed Timer” orange, and provides the perfect break between the dial and the glossy black count down bezel which can be rotated via the crown. The outer bezel features a black inlay, and the tonneau case is contoured for comfort on the wrist. In true JDM form, the day can be toggled between English and Kanji, and for a clean finish, we’ve paired it with a light brown distressed leather. 

NOTE* There is a visible blemish on the dial between the sub register and the day/date window. Provided are pictures for reference. I have considered this imperfection in the pricing of what’s otherwise an extremely nice example.
