This incredible vintage JDM Seiko Speed-Timer is the definition of cool - How did Seiko pack so many features into one watch while retaining such a balanced and appealing design aesthetic? 

How cool is the Japanese "Kanji" day display? Especially on Sunday when it turns to red... This particular Speed-Timer comes in great condition we have it on a blue pineapple leaf strap that really compliments the beautiful blue dial.

For peace of mind, the Seiko 7017 movement has been serviced a new old stock factory Seiko crystal and fresh gaskets installed at the time of service.

Here we have a stunning Seiko 7017 8000 SPEED TIMER FLYBACK, these are getting very difficult to find, let alone in great condition like this one. Everything is running beautifully and sharp, all of the stop/start and flyback functions of the chronograph work perfect, for those that are unsure of the flyback feature: The timer is started with the top pusher, then you can reset to Zero with one push of the bottom button, it will automatically carry on timing, this can be done over and over until you stop it with the top pusher again. The day/date snaps over at the correct times quick set day date works perfectly Its a large modern looking watch and and is showing very little signs of age or wear, Please study the photos to get a good idea but it looks and feels so much better in person. These are a rare find

A BIT OF TRIVIA

One of the seldom seen Seiko chronographs of this era, this 1971 Seiko 7017-8000 Pulsimeter SpeedTimer automatic chronograph - with its original instructions - features a flyback chronograph, which allows the user to reset the chrono function without resetting the time completely.  The flyback feature is similar to that found on Citizen’s 8110 bullheads, but rarely seen on Seiko watches.

 In early 1969, Seiko’s Suwa division would release the world's first automatic chronograph, it's famous Ref. 6139.  Yet only a year later, Suwa's sibling division, Daini, would respond with it's own automatic chronograph iteration in the form of the 7017.  The Japanese Domestic Market (JDM)-only 7017 is more compact that the 6139, and comes in a slightly smaller package, with the addition of the afore-mentioned flyback function.

 Another unique feature on the 7017 series was its quite svelte height of only 5.9mm, and it was only in the late years of the 1970s that this record slimness was bested.  The 7017 – similar to the 7015, but with key distinctions – was a JDM variant only, and wasn’t exported outside of Japan; it also wasn’t made for more than a handful of years in the early 1970’s.

 Seiko placed their movements into multiple highly unique cases, leading to a plethora of out of the ordinary shapes and sizes, not to mention allowing them the ability to stand out on the wrist.  This less common Speed Timer is no exception, with its unique "Pulsimeter Base" font in vibrant red, counts itself among them.

The Pulsimeter is designed to read a patient’s heart rate: Start the chronograph timer and count the beats until you get to the number the scale is calibrated for. Stop the time and you will read the heart rate in beats per minute.
