But while the interesting case materials are plenty cool, what these watches are really all about is that lume. It's the reason for their creation and Panerai fully embraced that idea. The lume in all three watches is a new grade of Super-LumiNova called "X1" that Panerai says is stronger and longer-lasting than other variants, letting them use it in the structural elements of the watch themselves. You've got the typical sandwich dial with lume on the lower layer, which lights up the time-telling functions, but there's also lume in the inner bezel ring, on elements of the crown and crown guard, and even in the stitching on the strap. Catching one of these watches glowing at night must be a sight to see. Hopefully, we'll have the opportunity to give you some first-hand impressions of this soon enough.
