Understanding Breitling's Serial and Reference Numbers
Breitling uses a unique dual reference number and serial number system for their watches. These numbers help identify a watch's production series and track its manufacture and sale. A true Breitling watch is produced with these numbers, and this becomes a key signifier of authenticity.Where to Find These Numbers
Both the reference number and the serial number can be located on the underside of your watch's casing. The reference number is a 12-digit code consisting of numbers and letters, whereas the length of the serial number varies depending on the model.The Meaning Behind The Numbers
The reference number is more of a code, with each digit conveying information about the watch type, movement, and certification. An example of how to break down the code would be AB011012/BF76, which signifies a Breitling Chronomat 44 in polished steel.Dating Your Breitling Watch
Serial Numbers and Production Dates
While the reference and serial numbers provide ample information about the watch, they do not include the production date. However, some Breitling watches can be dated using the serial number, especially if they were produced around the 2000s when Breitling began stamping watches with production dates. These dates are coded by week and year and are located on the case between the lugs at the bottom of the watch.Checking the Authenticity of Your Breitling Watch
