The sensitivity for turning on the display in nightstand mode is ridiculously high. I charge my watch with it sitting on top of an older style Philips wake-up light clock radio, before they switched to LED lighting in them, so there's a nice slightly cup-shaped area on top for the watch (and its charger, when it is not being used) to rest. Next to the wake-up light is two stacked books, a thick, heavy hardcover collection of select H.P. Lovecraft stories (a tome, really) which I intended to get through some day but never managed, and on top of that a Stephen King pocketbook brick. If I tap - lightly - on the King pocketbook's front cover as it lays there, the impulse will travel through - and perhaps magnifed by the eldritch energies contained within it - the Lovecraft tome, down into my nightstand, up through the clock radio's rubber feet and casing, and then microscopically jostle the watch sufficiently for the display to turn on.
Freakishly crazy! 😛
