If you purchase through Citizen Watch UK directly, we do not keep records of serial numbers on file.
The best way to identify your watch is using the model number.
The Model Number will usually be found on a black swing tag attached to the watch when purchased. The Model Number consists of a 9- digit reference number starting with 2 letters and 4 numbers, a hyphen, followed by 3 digits e.g., FE6140-03A.
Alternatively, you can also use the case number.
The calibre and case number can be found on the reverse of your watch in the format: A000-S015234
