Kabanata 247: Chapter 172: Z... Kulu... Nyagg... Rotip...

The pocket watch is not truly "charged" in the conventional sense, but rather displays an "energy quota."

"If I can obtain more Sands of Time, increasing the maximum quota to a higher level, the potential of this glory legacy will be even more astounding."

He carefully put away the pocket watch, calmed his mind, and began to keenly feel the various changes after becoming an Advanced Apprentice.
