There is a crack on the inside of the crystal. It does not reach the outside. (I imagine) The glass has a two-layer structure, and it looks like only the inner glass is cracked. Other than the crack in the crystal, the overall condition is "no noticeable scratches or dirt." All watch functions, including solar charging, work without any problems, but the auto power saving behavior is slightly strange. Even when the amount of light in the environment increases, it is difficult for the PS to switch from on to off. It seems that the crack in the glass is affecting the detection of "environment is dark → environment is bright." It has been confirmed in test mode that the solar and tilt sensors are responding. Would you like to use it in a way that does not subject it to excessive impact, or perhaps for parts?
