Lately, it seems that the offered length of power reserves has become a hot-button topic in watch-related discourse – but what do you need all those hours for? Are ~38 hours really not enough, especially in a casual or everyday sports watch? I never give total power reserve that much of a concern when it comes to divers and the like, but it's clear that the spec is of growing interest among watch enthusiasts.

I asked Jack and Danny to plug in their mics and help me talk over this novel need for more and more hours. And from early 8-day Cartiers to Hublots that boast 50 days of power reserve (and require a drill to winding) we dig into the need for a longer power reserve, some of the bigger PRs in watchmaking history, and some of our favorite power reserve indications.
