Double Rhomb NOS 70ies Handwind with Chinese markings

I found the following variations of those NOS Double Rhomb
watches
(please use the Back button of your browser to come back here)
Markings: Chinese marking below "PEKING CHINA" or no marking
Crystal: Inner edge of Acrylic Crystal decorated or plain
Case: Back: Old Double Rhomb Logo on Case Back vs. New Double Rhomb Logo
Hands: Narrow straight hands versus Broader pointed hands (we just received Double Rhomb models with all black framed hands, so that is an additional variation)
Please see my watch Sales Section for additional samples of those variations. I would love to keep all those variations in my private collection, but I have just too many watches already I am afraid. So I thought I would better offer other WIS to have such a unique NOS Double Rhomb in their collection as well
