In late March, the vintage watch world was rapt with attention over one very particular eBay watch auction. The listing was for a Submariner – but not a Rolex Submariner, a Tudor Submariner. And to be clear, it wasn’t even for the desirable “Big Crown” Submariner. No, this was actually a far more special and to many – including myself –  one of the most quietly interesting Rolex or Tudor dive watches of all time.
