Tudor Hydronaut

A discontinued Tudor dive-sport watch from the early 2000s, pre-owned only. The Hydronaut had a bold, blocky case and a chunky, of-its-era sport-diver look, in automatic, across Hydronaut I and II versions. It predates Tudor's modern revival, so it's a period piece rather than a classic, and an inexpensive way into an older Tudor sport watch for someone who likes the 2000s aesthetic.
