Just picked this up. Always wanted a Seiko with the 'traffic light' sweep seconds hand and this watch answered the need and it being a Limited Edition is the cherry that tops it off. I am talking about the Seiko SRP233J1 Diver's watch.
It comes fitted with Seiko's 4R36 movement. This movement is great after the popular 7SXX movements as the 4R36 offers hacking and hand winding capabilities, something I have been looking for on in a Seiko movement. This is a close I will got to a tuna. :)
