·Are you able to go see the watch in person and take some better shots? Is the seller wanting some astronomical price?
the only thing that goes through my mind is, that it my be a prototype and very rare...
You can collect watches without having books about them
.- and there is such a thIng as a one bottom chronograph pusher...
Research is the essence of this hobby so any serious collector will have all of the material available for him to do that research.
Whilst there are many single pusher chronographs and there are also dial-side chronographs, this is neither. It doesn't have any pushers and I seriously doubt that it is a chronograph as there is nothing to operate it. Also the movement would have to be ridiculously thick to accommodate the chronograph and the necessary wheels to drive that dial configuration.
