I'll try off the top of my head:
1. 43 hours - Mechanical hand wind (guesswork, and by process of elimiation)
2. 55 hours - Mechanical automatic 36000? (blind shot in the dark)
2. 55 hours - Mechanical automatic 36000? (blind shot in the dark)
3. 72 hours - Spring Drive automatic (9R65/9R15 have 3 days of power reserve)
4. 88 hours - Mechanical automatic 28800 (the new calibre used in the GS new lineup)
4. 88 hours - Mechanical automatic 28800 (the new calibre used in the GS new lineup)
5. 192 hours - Spring Drive hand wind (as found in the SBGD001 and the new rebadged GS logo equivalent)
6. 26000 hours - Quartz
6. 26000 hours - Quartz
Mainspring - I have no idea.

I think the mainspring
Is made of Spron. Not sure of the spelling off the top of my head.
Thanks for the quiz!

Thanks for the quiz!

Yes Spron alloy which seems to be made with Cobalt and Nickel. But it doesn’t answer to the question about the type of steel unfortunately 😕

No one has got it right yet.
Here’s a clue - some of the running time options are unnecessary...
SPRing micrON alloy details
SPRON is a spring material developed by Seiko. There are several flavors — 100 & 510.
In summary:
“SPRON 510 is a strain age-hardening type Co-Ni-Cr-Mo alloy with material characteristics that are more advanced than SPRON 100. It is non-magnetic and features ultra high elasticity and high mechanical strength, as well as high durability and heat resistance.”
