This Week’s Featured Watch #47 – the 67-9151 Chronograph

Time for a more complicated watch to be featured, and this one is one of the 8110A mechanical chronographs from the 1970s. The Challenge Timers, aka the ‘bullhead’ are the models most often seen for sale, many with after market dials and re-finished cases (see the buying guide: There are a number of other models though which are not so often seen, and the all stainless steel 67-9151 is one of those:

This model has an interesting case shape as well as hexagonal sub-registers, a dial design shared with one other model, the 67-9178 (see all of the models on the chronograph page:

The shaded green dial and contrasting yellow and orange sub-register borders, combined with the other design features are very 1970s. I have seen some very faded dials on these, and some which appear to have only yellow borders and more even colouring on the dial. Although they have the same dial code I am not sure whether they were a different original design, or have suffered a degree of fading – although two case numbers are seen on these so there may have been two versions (4-901118 and 4-901142).

My example was made in January 1975, and looks to be on an original solid link bracelet:

The clasp is signed:

Detail of the sides and signed crown:

The 8110A has a high beat movement, with hour and minute sub-registers, and ‘flyback’ capability in a compact design, features that represent a very good quality watch.

    HI: Just bought the exact same watch (almost perfect condition). Except for one thing. Case back says 67-9071. I know this was a part scavenged from somewhere. If everything else is so good how important is it to get the correct case back?

      Hi Gary, thanks for visiting my blog 🙂

      Congratulations on acquiring one for the rarer 8110a Citizens! Was it the one on eBay from Romania? I saw that and noticed it had the wrong case back. For a collector the correctness of a watch is important so getting the right back would add significantly to its value – at least to a collector. Other people may not be so concerned but even so if they were to do some research the back could still be an issue and would affect the likely selling price.

    You got it right Stephen: Romania it was. Being a beginner collector I was looking at the quality of the case, dial, hands, and when possible the movement. Oh well, I may have overpaid because of the case back. But looking at this watch, it shows like a NOS. I’ll keep my eyes open for the proper case back. I’ll find one someday and get this watch correct. I think it will be worth it. If you come across one, let me know. Thanks

      Hi Gary – it won’t be easy to find a correct case back, but let’s hope you can find one. The dials on these can be badly faded, so to get one like yours is great.

        Wow Sweephand: I found a poorly re-dialed 9151 from Philippines that I was able to pick up fairly cheap. The case back on this watch is original and in very good condition. I know I got lucky on this one. I can now complete my beautiful 67-9151 watch.
        Also a week ago I was looking at some of the citizens on the bay when my eye caught a really nice green 67-9071. Of course the case back did not match it. But because I really liked the way this watch looked and the price was right I bid on it and won.
        As I was putting my new case back on my 9151 I realized the one I was taking off is the one I need to complete the 9071. So by buying a poorly re-dialed 9151 I was able to complete two beautiful watches! I feel like the Citizen Sun God was casting a sweet ray of light on me. Not sure what I will do with the old re-dialed 9151 that I got. Since I don’t have the correct case back for it, but it is a very nice octagon shaped case, I’m looking for some ideas. Maybe I’ll just find a unique dial and put it together to make something just for my liking.

          Hi Gary, that’s great news about getting a correct back for your excellent 67-9151, and you’ve also made a good 67-9071 too, that’s doubly great 🙂

          If the movement is good from the re-dialled 9151 then it is worth trying to use it – they are nice solid cases.
