TISSOT Silen-T watch by Tissot. This is a high-tech watch that shows the time and other information when you touch the dial, and the alarm vibrates to alert you. At the 10 o'clock position, there appears to be something like a tiny air bubble inside. It could not be removed by wiping. Although it runs after replacing the battery, it is not accurate, and setting the time does not work normally, taking a long time. It is certain that there is a malfunction inside, so I think an overhaul is necessary. It is being sold cheaply as junk. Thank you. Color...Silver
