THE WATCH

Here we have a stunning black PVD coated Seiko 7017- 7000 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.

A BIT OF TRIVIA

Most enthusiast wouldn't have seen a PVD coated Seiko chronograph of this era, this 1972 Seiko 7017-7000 - 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.

PVD COATING

PVD stands for Physical Vapor Deposition. PVD Coating refers to a variety of thin film deposition techniques where a solid material is vaporized in a vacuum environment and deposited on substrates as a pure material or alloy composition coating.
