Hello HWL,
If you use the search engine here, you'll find a lot of information on this watch. To my understanding, M. Halter developed the movement base up i.e. he created/built the movement specifically for the Goldpfeil watch. The movement is not used in any other watch.
As for its power reserve, I can only share my own experience. It's an automatic movement. I don't wear it regularly and I don't keep it on a winder. But from manually winding it daily (20 turns of the crown), it runs for more than 24 hours. And it keeps the most accurate time among my watches.
Many here have shared their superlatives on this watch. I have nothing more to add except that if you have already found one, buy it
