All Suunto watches and dive computers have a serial number. The serial number is a combination of 6, 8, 10 or 12 numbers without spaces or dashes.
Depending on your product and its generation, there are several locations where you can find the serial number of your product:
In most cases, you will find the serial number printed externally at the back of the device module. Possible locations are:
In some cases, the serial number may be surrounded by a box. This may apply for e.g. Suunto Ambit3 Peak and Sport, Ambit 2 R Suunto Spartan watches, Suunto 9.
The serial number is added on a sticker to the product box sleeve as one of the last steps when packaging your product.
Usually all information on the box sleeve is printed directly on the sleeve, only the serial number is added as sticker.
In addition to the serial number, you will find several other numbers externally printed on your Suunto device and the product box which are NOT the serial number:
In Spartan Collection watches, Suunto 9 and Suunto 3 Fitness you can find the serial number in the watch under Settings > General > About > Serial number.
