This tool will decode your Tudor watch serial number and give you an approximate date of manufacture. To find your Tudor's serial number you must remove the strap at the 6 o'clock position and you will see it engraved on the case between the lugs. This tool supports all 3 of the serial number formats that Tudor have used over the years and covers watches from 1956 to 2002. I have tried to make it as accurate as possible but it may be a year or so out either way, it is as a guide only. The Tudor model reference can be found between the lugs on the opposite side of the watch so ensure you use the serial number and not the model reference, a model reference decoder is coming soon.
This does not validate if a watch is genuine or not, it purely translates the date code to find the year of manufacture. If the watch type was not being manufactured during the year suggested by the serial number then it tells you that further investigation may be required. If the serial number starts with an H or B please include that.
