Birth year Sub 16610

[Alvar*]

I have the opportunity to buy a sub 16610 (tritium, drilled lug holes). Condition is pretty decent with original tritium parts. Case and bracelet seems fine and not overly polished. Price is steep (unsuprisingly), around 10 k usd. Original papers but no box. From a trusted grey.

The thing is, that according to papers it happens to be a birth year version from the early 90s. Am I crazy if I pull the trigger on a nearly 30 year old watch that costs 10k. Are birth year watches overrated? Is a sub this old still a decent daily driver?

Looking for opinions.
