Swarovski SLC 10x42 serial number help

[CleanShot]

Hello

I found a pair of used swaros that have a serial number starting with D7120. They are SLCs in a 10x42. Do you guys know how I can age these? Are these the latest model?

Thanks
Sam

From what I have heard (and read), you had 30 to the first two numbers, and the sum is the year of manufacture, so I am thinking yours would be 2001?
