Men's wristwatch, an old TISSOT chronograph. It is running. Time and calendar functions are normal. There is no particular gain or loss of time. The belt is an aftermarket adjustable mesh belt. The long hand of the center chronograph starts and stops with the upper right button, and resets with the lower right button. Its operation has been confirmed, but the hand of the small circle on the upper left (accumulator?) does not move. The upper right circle moved when adjusting the hands, but I don't know when it's supposed to move. The lower second hand is running.
