Some brands are timeless
While watchmakers like Casio and Citizen might be good candidates for a smartwatch, I can't really imagine traditional watchmakers like TAG, IWC or Rolex making these kinds of watches. OK, maybe TAG, but for the most part the watches these companies make are more formal, upscale and traditional. They make statements. People who buy these watches are making statements. THey also appreciate the watch for its craftsmanship and traditional functionality. A digital design would certainly cheapen the brand and make it more accessabile to demographics that are not desired by the watchmakers.
