Reply With QuoteMy instant reaction on seeing the way that Q was written was Seiko but I have no evidence.
I have acquired an old Rotary watch. It is a quartz movement. I want to know who makes it. All I can see on it is a big letter Q and the numbers 590. Its just hr min sec. There is no date window.
Thanks everyone.

I think it is a Ricoh movement. This link seems to have some relevant details. http://www.crazywatches.pl/ricoh-590-riquartz-1975Originally Posted by Fizzy500

Looks about right to me. I could find it anywhere.
