Personally I find the hands to be VERY important. Way way more than the number written on the dial, or any sort of "literature", name or logo... It's the visual identity of the watch and since I'm not diving to more than 60-65m anyway, even the technical performance is clearly less important. That being said, the first type of hands was good. Maybe a bit small and "usual" if you really wanted to find problems. But they were good.
Among those proposed after the "new ones" with the Seiko Tuna styling are the "least catastrophic". I could see myself buying the watch with them.
The "screwdriver hand set" (or snake head): deal breaker.
The "proposed for the scorpionfish" (with the Chris Ward/Bremont hour hand): massive deal breaker (the one reason I never got and never will get a CW trident or a Bremont)
The modern pencil set as found on the scorpionfish is a possibility but I fear it'll look small and bland on that big nasty deep diver. To be tested, however.
Now the one set I modified, I like very much, as I feel it retains the bold and original nature of the original "Tuna style" but in a more balanced (to my eyes) fashion. But... as phlabrooy pointed, that probably means special order, added costs, and so on, and that's probably to be avoided, as "mega value is the thing" at Borealis!
So all in all...
1°The set I modded I like the best, but...
2°The set in the first renders, on the first page, is great.
3°The set in the second render, I could learn to love it.
4°The modern pencil could possibly do.
The other things mentioned/showed are big, resounding, NOs.
