Greenwatch mentioned the curious power reserve hand on his recently acquired GS Spring Drive "Snowflake". That prompted this post because it's quite an interesting feature that explains a lot about watchmaker movement architecture and designs. MANUAL WIND...  

Thanks for the little excursion into SD power reserves. Is the Space Walk like the regular chronographs? Need to check... And somehow missed the fact that you have a Galante - very avantgarde!

I vaguely recalled that there was something different about the Space Walk and Landmaster

May I ask what is the reference of your Credor spring drive with the little moon phase?

There’s a dark dial variant too but I’ve never seen it in person. Mike

The amount of time and effort put into the research is definitely phenomenal! Got to learn PR principles as it applied to watches. Many thanks!
