From a recent post by ismy noticed something that may have been an inspriration to the designers at Beijing
pretty close imo
One that was a surprise when posted elsewhere
prefer the BeiHai myself though
Granted there are many generic out there, by many different makes, and when the Chinese started watch production in the mid 50's a few designs must have been common too.
Seagull have a few older classic designs come to think of it.
Please post thoughts on others as and when, cheers, Dave
