^^^ This is the big thing. Just because a watch advertises C3 Superluminova, does not mean they have a thick enough application to make the lume glow bright. It is all about the application. I have a Dagaz CAV-1 with C3 that glows like a torch through the night. I also have a PAM homage with C3 superlumiova that glows for a long time, but only has a small fraction of the brightness.The intensity often relies on the amount of surface area that is covered by the paint and the thickness of the application.
