Great looking piece, and a very interesting bracelet...nice buy!
Oh, and I always wondered what a "flyback chrono" was, thanks for the explanation.

I never knew what the term meant either.
In other words its acts as a "Hack" feature!?

If that the case then why would you want to start, stop and reset the hand?

Like the 700x series watches, the 701x chronos have been unfairly maligned for a very long time. My 7017-6020 is one of the most accurate chronographs I own, and like other members of the 70xx family, the movement is beautifully made. All-metal, nicely finished, accurate and strong.

Interesting watch Tom . . . congrats.
I like the dial a lot and the bracelet is also very interesting.
Enjoy it in good health!

More on Fly-back:
Yes, you are basically right in your explanation. To amplify though ... on a "regular" chronograph, if you want to take successive readings, you have to:
1. stop the mechanism with one button
2. reset the mechanism (accumulators) with another button
3. then restart the mechanism with that 1st button again.
If you need accuracy in measuring a 2nd event that starts "instantaneously" after the 1st event ends, you are basically out-of-luck with a regular chronograph. With the fly-back, you just hit the reset button and it does ALL 3 steps "at once", allowing you to get a much more accurate timing of the 2nd (and any other subsequent) event(s).
The Citizen chronographs [8100, 8110, and 5700 (seconds only)] operate in the same manner. The 5700 is manual wind by the way.
Here's some of mine following (I'll just post this so I don't lose it & come back w/ the pics in a subsequent post, OK? Got to go access the pics elsewhere 1st).

Here are the Seikos 1st. 7015-7020  I've since installed the proper crown/stem & had it serviced. It came in at a very reasonable price due to the problems & being "head only". Now, it is a seconds-only chronograph like an Omega Chronostop - but it does function as a "real" chronograph for short interval timing. BUT: with the rotating timing ring you can use it like a 6139 to accumulate minutes as well as seconds. It can also function as a "hacking" feature if you run the seconds hand constantly rather than just use it for timings. Also notice that (AFAIK) it is the ONLY Seiko chronograph of the '60s/70s that had actual crown guards in the case design! 7017-6030  One you do not see often, to put it mildly. 7015-6010 TimeSonar  7016-5020   I'm especially proud of this one. It came from the stock of a retired watchmaker/seller. It even has the original Rally strap on it!! And the clear oval case-back sticker!! Not a trace of wear on the "gold" plating too! 7017-6040  This one was beautifully reconditioned years ago. Only problem is that the outer dial chapter ring is not the "standard" one for this model, it should be a rotating timing ring, but I like the look anyway. OK - you notice that functionally, the 7015 & 7017 are the same [seconds only]  I've NEVER been able to find out what exactly is the difference between a 7015 & 7017. All the documentation I can find, all the movement pics I've seen show no functional or architectural difference!! It's a mystery to me why they have the 2 separate calibres!! OK, you've seen my 7018 Timesonar elsewhere, so I'll leave that out. I'll post now so things don't get "lost" & come back w/ more, including Citizen. |

7017-6050    One of my favorite visual designs in this series!! There is also a -6020 with almost the same design (differences in dial) plus a 7015 with same features, but different color scheme. 7017-6010 If I remember correctly,  It's on a Seiko bracelet, but likely not original style. Now, for some Citizen: 5700 Recordmaster-RallyCustom   These are incredibly hard to find in any decent condition. Note that it is HAND-WIND, not automatic!! One of my favorite 8100 models. This one is almost Mint & came on an original strap!  Got it years ago from Singapore. The following is a "fantasy piece" supposedly a 8100-4-90003T-TA-900062Y - basically has a swapped outer bezel from an 8110:  Again, from Singapore. I'd told the seller it was a "franken" & got a big discount ... but I still like it. Even though "cobbled" the bezel is quite hard to find in good shape & I think it actually adds value to the watch! Of course, it makes the watch have 2 separate Tach tracks which should have been a dead giveaway to the seller who was normally quite knowledgeable about these. Now, here's the REAL THING from my collection, an 8110:  Again, from Singapore and almost perfect ... just a missing lume dot @ 9. I got this at a good deal too! Not sure why folks didn't snap it up right away - but I knew what it was & waited for the seller to lower the price & pounced when I thought it a good deal! It was Years ago, I'll add. Off the top of my head, I don't know the model #, but the seller dubbed these a "Spaceman" & that name stuck in certain forums years back. Next, a cushion cased 8110 with what has been termed an Art Deco bezel:  Also from Singapore around 2000 or 2001. Finally, the "Baby Speedmaster" type of 8110. Sorry for the horrible picture following, seller's shot - it looks quite nice in person:  At least I was able to get it at a quite reasonable price due to the lousy shots!! This one came from Israel in late 2000 2001 & likely had a locally-done modification. It changes day/date at 6PM!! That is an approximation of sundown when (in Middle Eastern culture) the day ends, rather than midnight! You can go to Sweephand's Citizen site to get actual model #s for the above examples: sweep-hand.org/Hope you enjoyed the view!! |

Great additional info on the Fly-Back chrono. I wasn't aware that you could just reset the chrono in the running position without stoping it first. I just gave it a shot on mine and it's pretty slick....... Great collection of 701X's you have! |

Some great stuff here, guys! I used to collect the 70-series chronos, but I don't buy many anymore. They are quite a bit more "finicky" that their 61-series cousins, and service parts (like gaskets) aren't readily available. I still have a really nice 7017-8000 Speed-Timer that is waiting on pusher gaskets...  |

I wasn't aware that you could just reset the chrono in the running position without stoping it first. I just gave it a shot on mine and it's pretty slick....... Thanks a lot for your appreciative comments guys! I too was amazed by the "action" of the fly-back when I 1st got one (after having just a "regular" chronograph for a few years). It is cool to watch ... and darned effective if you need to use it for it's actual purpose! On the 70 series being "finicky", yes I think you do have to use them "gently" ... mine are all gently treated, but then again I do gently use the regular series of chronos [Seiko as well as Swiss] as well if they are "of a certain age". I suspect the service part lack of availability on 701x models could be due to their relative obscurity in collecting communities (outside these specialty communities) vs. things like the 613x chronographs that even many Swiss collectors have knowledge of now. Actually now - like you w/ the 70s, I really don't collect chronographs & alarms & diver/sport models anymore. I have to really watch "growth factor" in the collection. In recent years it's been usually gold cased dress watches, especially if they have "hi end" movements (for their time period or manufacturer). UPDATE: Be sure to look over the database pages for the 701x chronograph series @ Dr. Seiko (though a few aren't finished): 1. Section header for 601x & 701x (has some Seiko reference material scans as well) seikoholics.yuku.com/sreply/218/Seiko-Chronographs-Automatic-Catalog-Ad2. 7015 header: seikoholics.yuku.com/sreply/222/Seiko-Calibre-70153. 7016 header: seikoholics.yuku.com/sreply/223/Seiko-Calibre-70164. 7017 header: seikoholics.yuku.com/sreply/224/Seiko-Calibre-70175. 7018 header: seikoholics.yuku.com/sreply/225/Seiko-Calibre-7018In putting together that database, I realized that there is a lot more reference material around for the 613x than the 701x family! |

<abbr>Don,
I realize the 7019 is not a chrono but wondered if it is a Daini product like the rest of the 701x family?
There seem to be enough differences between it and the 7009 that it might make sense.
