You have an excellent collection.I have a few...
I also have that black helicopter dial. I was wondering when someone would post a photo of one of these.
They seem rather rare.
Your collection shows how good those 'Dot' bezels are. They are narrow and fairly plain so their minimalism allows each dial to catch your attention - they don't compete with the dial.
Now we know where all the 2 O'Clock crown models have gone.!
