Citizen 150m

Mitka · Aug 23, 2026

Hi everyone.

I’m currently working on a collectors guide for Citizen 150meter rated watches from 1964-1980. Photos of your example would be greatly appreciated!

Best regards,

Mitka

Just mundane Challenge Divers, but I'm happy to post better photos if at all helpful, Mitka.

OK, front, back, and crown.

As you probably know ...

the lume plot at 3 near the date window is distinctive
regarding the sweep hand styles. I've really tried to study this, but I'm still not convinced that there is a clear rule about which references have which hand.

OK I will start with some that I've sold because I have photos on hand. I will do one watch per post. I will also dig out the ones I still own and take some photos.
