The current 15x56 was introduced in 2013, and is model 58291
(the previous model - which is a totally different design - was produced to 2013, and is model 58191)
All current x56 models have a serial number starting with the letter N (the earlier model started with D)
MODEL NUMBER LOCATION
The model number is not marked on the binocular, but is part of the UPC number which is on the box label (see the example from the web)
On the label:
- UPC stands for Universal Product Code, and
- EAN stands for European Article Number (it’s otherwise known as the IAN - International AN)
Both the numbers and the associated bar codes are designed for computerised stock management
WHAT’S IN THE NUMBER
The UPC is 12 digits with 3 components:
- the first 6 digits comprise the company code (Swarovski Optik)
- the next 5 digits, the model number (in this case the current 15x56)
- the last digit is an algorithmic check digit
AND TO FILL IN THE MISSING DETAILS
The EAN is 13 digits with 3 components:
- the first 3 digits comprise the country code (Austria)
- the next 4 digits, the company code
- the last 6 digits the product number
If you need the model number when ordering, it will be the UPC one, 58291
Happy viewing
