This Week’s Featured Watch #17 – 67-9577 Chronograph

Following the 67-9038 in my last ‘Featured Watch’, it seems logical now to present the other  automatic chronograph line by Citizen, this time with one sub-dial. Both movement types were introduced in 1972 – the twin sub-dial being the 8110a (there was never a ‘b’ version!) and the single sub-dial 8100. As with the 8110, this type has 23 jewels and uses the central sweep hand as the second counter, whilst the sub-dial counts minutes. Otherwise its features are the same, running at 28,800 beats per hour with hand winding and ‘flyback’ (instant reset and restart of chronograph function without having to stop it first).

Good examples of the 8100 are not easy to find, rather like some of the lesser known 8110 models.

As far as I am aware the 67-9577 was made with two dial designs, in the same black case with stainless steel bezel (edit on 10th December: possibly a third dial design now found which will be shown on the Chronographs page once I’ve finished it!) . Here’s the first type, with black dial and lumed white main hands and orange chronograph hands:

This one was produced in October 1972:

And is shown in the relevant ‘museum book’:

The second design is a more colourful model, featuring a blue dial and white inner tachymeter ring, with a brightly contrasting orange hand set and orange highlights on the hour markers:

This was produced in July 1973:

For reference purposes, note the different dial codes for each model: black is 900071-Y, blue is 900062-Y.

Finally, here’s a group shot of these two 8100’s alongside the 67-9038, to illustrate the design similarities and differences:

  1. Hi! I have one NOS with blue dial…!

      Hi Kostas, thanks for dropping by and posting a comment. And even more thanks for linking to your pic of the watch, it looks superb! These are hard to find, and to have one in mint condition is brilliant.

      Do you have any more vintage Citizens? Would be good to hear about them if so 🙂

      I’m working on a page to add to the blog about the Chronographs – with the 8100 and 8110 movements – I just need to do some more work on the Challenge Timers (‘bullheads’) since there are so many with aftermarket dials which I want to filter out.

        (Sorry for the repost, but the first was send before I spell checked) you know the watch band size for this watch? I have one in pristine shape but without a band. I admire the black one in your picture with orange threads. Is it aftermarket or and original that came with the model also. The one I had was solid black and not nearly as attractive. Also, in time, age and exposure caused the rubber to crumble into powder. With a nice replacement band, I’d like to get the watch back into use.

        • sweephand says:

          Hi Sonny, thanks for visiting my blog 🙂 The width of the band for these is 18mm and the one you like is a new one I bought for this watch. I think I got it from a UK supplier – TSS Watch Straps – but it’s not showing on their web site now I’m afraid. Here’s a pic of an original ad for one of these chronographs:

          It looks like it might be one of these – sadly the leather is like paper on this so I can’t use it:

          Let me know of you want me to contact TSS (I can email them since I’ve bought a number of straps from them) to see if they can still get the one you like.

    Hi Stephen!
    apart from the 67-9557 I posted, I have the following: 67-9631, 67-9038, 67-9119, 67-9313 and an almost mint 67-9071 which is missing its chrome bezel. If somebody has a donor watch I would be glad to buy it !
    I will try to find time and get photos of all them together and post them here!
    Greetings from sunny Greece!

    • sweephand says:

      Hi Kostas, sorry for slow reply, I’m away from pc and mobile connection is not good. Will reply properly in the next couple of days I hope.

    • sweephand says:

      Hi Kostas – you have a nice collection of chronographs 🙂 The 67-9071 doesn’t come up for sale very often, so I wish you luck in your search.

      Which 67-9038 and 67-9313 dial colours do you have?
      Regards from a very wet UK!

    Hi again! I found another 67-9071 for donating the chrome ring but there were two surprises…the case is different! The curvatures do not allow to exchange the chrome bezel…and the chrome plated bezel is actually completely made out of steel…I do not know what to do now; I have never heard of variations existing for that model, so I will continue with my search for further specimens of that particular reference. My watchmaker may resurrect the donator watch to a working one but this was not the initial intention and since we cannot reapply the black coating with reasonable resistance to wear (at a price that is normal) it will probably be a wearable chronograph not in the original configuration.

    • sweephand says:

      Hi Kostas, sounds very strange that the bezel from one does not fit the other. As far as I know there was only one model – could it have been re-shaped by excessive polishing do you think?


  4. Do you know anyone who can replicate the leather pieces for this straps. I have teh original one but the original leather is worn out. Thanks!

    Hi, Stephen! Is it possible to have a 67-9577 model Bull-Head? Thanks!
