·Tudor serial numbers are not generally the same as Rolex (although perhaps they coincided before the Rolex serial reset in the mid-50s, this remains controversial). It's not easy, but you can find some good research on the internet, and combining various design aspects and the serial number, you can probably get an approximate date. But don't expect precision. Things seem somewhat better researched starting in the 60s, and then there was a Tudor reset in the mid-80s.
