The 67-9313 chronograph from the 1970s, known as the ‘Speedy’ was originally sold on a steel bracelet. So far I have not been able to find a clear catalog image so it has been something of a mystery. This is the best I have found!:
Over the last couple of days a guy called Steve, from the USA , and I have been talking about this issue – both of us have white Speedies that came on bracelets thought to be original, so we have given it some thought 🙂
The first point to be made is that the case has been designed for straight ended links. Steve provided this photo, showing how the space between the lugs has been cut out for a straight fitting:
The bracelet on both our Speedies fit this gap snugly:
Interestingly bot our bracelets have a slight dent on the centre of the end link where it presses against the upper case – Steve’s:
Mine:
I’ve found a few more on the internet with this bracelet, and it appears to be the same style as the catalog image. It’s folded link, with no part number, but our conclusion is that this is most likely the original bracelet…..
With thanks to Steve for his input and photos 🙂

I have just got a ‘speedy’ from 1976 directly from the original owner. It has half of it’s bracelet intact and it looks identical to these two. The owner vouches for the fact that the bracelet is the original one. The watch itself is a bit curious. The day window shows in both English and French?
Hi Neil – thanks for visiting my blog, and for telling us about your Speedy and its bracelet. It is very helpful to hear some confirmation about this bracelet. Many watches had dual language day wheels in the late 1960s and 1970s, aimed at different markets, all had English as one option. Citizen list English/French and English/Spanish for the Speedy in their 1977 casing catalog, presumably for European markets. English/Arabic is also seen quite frequently.
