Royale Men’s Watch vintage RYL506 Quartz

vintage wristwatch new battery popped in tested 12 hours and it kept time gold and silver tone metal band vintage condition with scuffs from storage with other watches small scratches on the face around the number “9”. Had to search for it - face is in pretty good vintage condition a little stone at 12 o’clock - can’t find the research to determine if it’s a diamond, so unknown 9” around offers welcome
