Manyhybrid watches only resemble classic timepieces on a superficial level. If you want a watch with a true mechanical movement, you have to forego modern conveniences. Ressence wants to fix that with its newly unveiled Type 2 e-Crown Concept . The watch, designed with the help of Nest co-founderTony Fadell, only requires conventional setup when you initially set the time. From then on, a paired iPhone app can automatically set the watch to one of two time zones using its namesake e-Crown. If the power reserve runs out or Daylight Savings Time kicks in, you don't have to use the old-fashioned setting mechanism unless you want to -- you just have to tap on the watch face.
