Fascinating watch for anyone who lives by the ?In the neighborhood? time lifestyle. The idea is that each hour is represented by a different color. It supposedly only moves a wedge each hour. We replaced the battery (SR621, 164, AG1) but alas it does not seem to move. The battery did not fit in as snuggily as we would have liked but it should have enough contact if it was working to move forward each hour. Therefore, we are going to put it out for someone who might need the parts -perhaps the crystal or a basically new watch band from ChromAchron or perhaps someone thinks they can fix it. That is not us. Because it?s listed as ?Part or Repair? we do not offer returns. Very cool and interesting watch and hoping it?s an easy fix. Will ship USPS with tracking to winning buyer
