Josh's Watch?

Hey guys, really short and simple post that I'm certain has been done before - I'm sorry for that, but there's no forum search system, so, alas - but I was simply wondering if anyone knows the model of Josh's watch. I know that the band is one that he purchased separately from his discussions in the Vergecast on smart watches, and that he inherited it from his grandfather, but I really love the face, so I'd love to know.
