I have this Mathey Tissot ladies watch. It belongs to my wife. She does not know anything about it an is intrested on finding out how much its worth and maybe some history about it. The band may not be original, as it says lizard skin Italy on it. Round watch about nickel size face. silver color cable around face with gold tabs around cable. Watch says Swiss at bottom below 6 o'clock. Back is brushed silver color. Around what year was this from? thanks for your assistance
