I thought I would like the circular power reserve indicator since I never really liked the fang indicator. But the more I looked at the circular indicator, the more I didn't like it. I think if Panerai changed the look of the circular indicator, I might like it better than the fang, but with this current layout, I don't like it much.
Also, maybe give the hand another shape such as an arrow or anything other than the Panerai leaf hand so it differentiates itself from the other hands on the dial.
Cheers,
Anthony
