I've been looking for a birth year Rolex from 1972, but there seem to be so many sites with Rolex serial numbers - many of which vary substantially.
As a result, the watches I look at invariably show as coming from anywhere between 1971 and 1973, depending on the site referred to.
Is there any particular site considered the definitive resource for Rolex serial numbers, as per the members of this forum?
I'm currently looking at watches with serial numbers 334xxxx and 371xxxx and both watches are listed as being from 1972 by the sellers.
Thanks in advance for any input you may have!
