I believe it’s likely that some divers would not have been brought to the market in the same year the movement was first produced. I have included dates against each movement number, which is the date I understand the movement was first produced, but this may not be the year when the diver model using that movement was introduced. They are not included here, at least for the time being, since I have not got the necessary reference material. I indicate in the article with a ‘?’ (sometimes with notes as well) where I am not entirely sure about the data I’ve gathered, and I welcome any comments about the information so it can be developed and firmed up over time.Īlthough this page covers Citizen’s mechanical divers, I appreciate that they also produced some excellent quartz models in the late 1970s, most notably the 600m rated Crystron. I hope information can be added later, or errors corrected, with the help of fellow collectors so it as complete as possible. Although I’ve tried to make it as comprehensive as possible, there is little information available elsewhere so I regard it as ‘work in progress’. This page brings them all together in one place as a reference point.

A few are relatively well known, but others are not and are rarely seen. Citizen produced a range of divers in their 1960s and 1970s line-up.
