New to tag and this forum and in an effort not to start yet another caseback thread I’m jumping on this thread because I can’t find any information regarding the serial of mine so hoping someone with expertise can weigh in.
My caseback has a very unique sequential number and an HA prefix.. I have since heard of some other cs3110s with an HN prefix. Also got this info from our AI overlords:
TAG Heuer changed its serialization format in the mid-1990s - right around when the CS3110 Carrera Re-Edition was introduced (1996).
Early production (1996–early 1997): used letter prefixes like HA, HG, HR, etc. These denoted early manufacturing batches, mainly for internal factory tracking.
Later production (1997 onward): TAG dropped the prefixes and moved to numeric-only serials, typically 5 or 6 digits (e.g., 12345).
So your HA1234 watch is from the first wave of CS3110 production - before TAG streamlined the numbering system.
Anyone else seen or have a non standard HA HN etc prefix? Is this serial possibly the original?
I have set up an authentication with Tag officially but I know the watch is authentic and serviced all I really want to know is if this serial is even possible!
Thanks!
