Cal 8800 question

[Fifitek]

Hello,

i ve got question. I had a few watches with caliber 8800 and the last I bought was pre owned aqua terra 38mm. I pointed the numbers near the SN. I haven’t got them in my others 8800 calibers. What does it mean ? Is it all legit / prototype ? I ve got all papers and receipts.

Edit: it seems ok, the same is on official website 😁…

kind regards
