The cover on the back or inside of the back typically they don't have serial numbers just model numbers.
Thank you hope this helps

there are two sets of numbers,like this, REF MODEL NUMBER AC38TA SERIAL NUMBER L30***

Model numbers and battery details etc. on Pulsar watches are normally stamped on the back plate but the serial numbers can sometimes be found on the inside of the back plate.

Numbers on case back are inside. Number on case is outside, located between lugs. You need to remove bracelet to see it. Rate me, plz.

email Kcole on the web with serial numbers of the case back or try ebay again you need model and serial numbers

Yes they do;

To see this go to the TAG web site "tagheuer.com" and select "watches".
Now select "aquaracer" and you will see a list of variations.

specific serial numbers are usually on the box or the reatilers tag. Caseback numbers are enough for ordering and service. These are the numbers on the back of your watch. If there is more than one number there then 1 number is the style number and the other is the serial number. For more specific info I recommend you contact [email protected]

Send an email to Citizen, they are glad to help you. Numbers are located on the back, send them all numbers, they will tell you what to do.
