Hi,
I know there is a logic to the number, but I can't remember
Something like: year of build, sequence number, etc
Does anyone know?

Most Raymarine serial numbers start with "E" then 12 digits. First 5 digits are the product number, last 7 digits are the serial number. First 3 of the last 7 digits are month and year in MMY sequence, so for example my C120 display is E020221240530 - made in Dec 04.
