Legacy / Birthyear Watch

[_speedmaster_]

So, my first child (boy) is scheduled to arrive this coming October. *my avatar does not accurately reflect how I feel about it*

Anyway....I was thinking of getting a birth-year watch to mark the occasion. Something that would be special, that I can enjoy for a while before I pass along to my son when he comes of age.

The only caveat being that I would want to acquire it by October (so no extremely hard to get watches). I was thinking of the TT CHNR to mark the occasion and have as the heirloom (talked to my AD and am confident I can source by October).

Just posting to hear about other members' birth-year watch stories. Also to gather some alternative opinions to the TT CHNR (maybe non-Rolex)?
