I considered posting this request for opinions in Shum's dedicated Certina thread, but decided to put it in a dedicated thread to maybe attract the attention of others than Certina specialists, since the movement is from Valjoux.
I've been looking for an Argonaut Chrono for some time, but I want to find a good - though not too mint/NOS - example. This one is up for auction at you-know-where. I can see myself that the corners are not as sharp as on the most pristine specimens out there, but since I intend to wear the watch I wouldn't really want it to be NOS or too minty since I would then feel bad about wearing the watch.
What are your opinions on this one?
