Hello. I have another question about my new Citizen Aqualand 20th. Anniversary Watch. The serial # on the back case is 9 digits long. It is 231020091. All the pictures and reviews of the watch I have seen show 6 digits at best. I bought the watch from Jomashop and are starting to wonder if this watch is truly a Citizen. Can anyone share some insight into my situation. Thank you, Brian.
