I’ve been wearing a 1967 Crystal Date for the past couple of weeks – this is the date only version of the Crystal Seven, and is one of the 52 Movement Family members. This 17 jewel model has the 5401 movement in it (54 = date version, 52 = date and day version):
I really like the lumed hand set on this model, especially the elegantly slender minute hand. But what is really impressive is its time-keeping performance – I haven’t had to adjust it for two weeks, which is quite remarkable in my opinion for a watch of this age and with no recent service / regulation. I suspect many modern high end mechanical watches would do no better than this I suspect.

Hi!
Congratulations! That IS really impressive timekeeping perfomanse! But it is not surprise, thought, I have had samekind of experiences with my vintage Citizens, too. Well, maybe not as good as yours but quite close to that. They underestimate quality of the Citizen !! 😀

Hi Marko – I agree, many of my watches, all vintage Citizens of course 🙂 run very reliably and accurately, even the more ‘basic’ models,
