With many thanks to ‘Vlad’, I’ve just added images of his very nice 100m diver, from December 1969, to the diver reference page (https://sweep-hand.org/citizens-vintage-divers-1962-to-1980/).
Vlad kindly offered his images for the archive, and it is such a nice example I thought I’d also add a post about it here. Blue and orange dials were featured on the export models of this watch, and different shaped hands from the ‘Parawater’ versions were also used:
The watch is in very good condition, especially the bezel insert which can get rather chipped and faded over the years:
The case back is typical of its day, showing case (4-520858) and model (61-5773) numbers:
Inside is the 21 jewel day and date 52 movement – the black rotor appears to be the standard type on these:
Both the orange and blue dialled versions of this watch are quite rare, and I am grateful to Vlad for allowing his photos to be used here.

Thanks Stephen for the look at an outstanding example of an iconic watch! Hard to believe this one is nearly 50 years old. m.
Hi Marvin – yes, it’s looking good 🙂
Good morning Stephen, Great watch indeed! There also is a “2 tone” version of this orange dial watch with yellow. Mine dates from april 1972. If you need pics for the archive, just let me know.
All the best, Bert
Hi Bert – thanks for your comment and I’m very interested to see pics of your two-tone model 🙂
I have a blue dial version of the citizen 4-520858 that I would like to have serviced. Can sweephand recommend a shop where I can send the watch for service?
Hi Chris, thanks for visiting my blog. You have a nice watch 🙂 To help advise you can you please tell me where in the world you are? Stephen
Thanks, Stephen. I am in Charlotte, North Carolina.
Thanks Chris, assuming you would prefer to have it serviced in the USA, I’ll make enquiries (I’m in the UK) and get back yo you asap. Stephen
Hi Chris – I’ve been in touch with Brian Leiser, master watchmaker, and he would be able to take a look at your watch. His work is featured on this blog, so he comes with excellent recommendations. He is in Pennsylvania.
I’ll email his contact details to you.
See his work here:
