Watches

I’m looking to get into historic watch collecting and was wondering what the most “authentic” historic watches are. Here’s what I mean by that:

I want to purchase new watches, at least to start, but I want them to have historic significance (think the Omega Speedmaster having been the first watch on the moon or the CWC G10 having been sold to the British MOD at the end of the Cold War). Ideally a watch would still have the original build and be manufactured by the same company.

Extra interested in military watches, but open to any and all suggestions!
