How did Skye's watch work here?

[Spoilers ahead...based on material up to Season 2, Episode 11]

Electronics do not work in the underground Kree city in Episode 10.

Yet in the next episode Fitz analyzes the biological metrics from the watch Skye was wearing during that time.

The data recovered from the watch turns out to be a crucial plot point, as it leads Fitz to cover up Skye's transformation from the rest of S.H.I.E.L.D.

Is there an explanation for why electric flashlights didn't work, but Skye's electronic watch did?
