One thing you'll notice while wearing the watch is that the crown doesn't actually wind the movement. And yet, it's a manually-wound watch. I mentioned that energy efficiency is key and the fact that
link the "house" rotates on its foundation isn't just a
link parlor trick. Each
link 45° clockwise turn not only gives you a tactile click, it delivers 72 minutes of power directly to the barrel. After 10 complete rotations, HM11 is at its maximum power.
