With thanks to Mikko, I’ve been able to update the Chronograph page. In particular the section on the 67-9143 (black case / gold dial) model has been amended to clarify that Citizen appears to have used two different case numbers for the same (67-9143) model. At the moment I can’t see any differences – Mikko and I wonder if the coating might have been different but having looked at a number of examples I can’t be sure of that.
The case numbers are 4-901134 and 4-901088. If anyone can help identify any differences, please post a comment
I had previously included this model as an example of a 67-9143 with case number 67-901088:
However, I now think this may have had an incorrect case back. It appears to be a variant of the 4-901096, so I have referred to it in that section, but without verification or case / model numbers:
Here’s Mikko’s 67-9143, a fine example of this model – they haven’t always worn too well over the years!:
Thanks Mikko 🙂
Sweephand's Vintage Citizen Watch Blog 
Dead all,
I just acquired a example of a 67-9143 chronograph. Looking into your blog make me think that the dial in a vintage piece (serif, police size…) But I wonder about the day and date colour.
One thing sure, the back on the watch didn’t match the case because the back is an 67-9020 “GPB” but the case is dark brown and the bezel gold plate. So I’m trying to discover if the back is matching the dial of the case is matching the dial (quite a detective case, I love it).
I notice that 67-9143 have white day date background with black police and mine is black Background with white police.
could this be a clue that the dial and mouvement use to be in an 67-9020 case and not 9143?
This post is old but I hope my bottle will find a reader.
cheers
Nicolas
