Year built from serial number? Fenix 6 age :)

Hi all, wondering if there is a way (a database or anything similar) to determine (or approximate) the "age" of the watch from its serial number.

Reason is... Bought 2 watches (plain Fenix 6) on Amazon warehouse - as "used in good condition" while they look basically both brand new; they have serials almost 200k apart (63N36xxxx and 63N58xxxx) apart, curious about how old are they respectively. Also, anyone knowing approx how many Fenix 6 are built every year?

Understand there is no direct connection between build moment and sale moment, nevertheless... I am curious Grin

Thanks!
