Extraordinary watch. It's also one of my favourites. And not only optics, it also seats so good on the wrist, perfect size and it runs extremely exact, no matter if on the wrist or in the box. And you can still can get quite good examples (in comparison to Speedys), nevertheless they were made in total only 2500.
Here one for sale if you want:
