Seiko released a 7C46 Tuna Can with a blue shroud to as one of the commemorative watches for its 130th anniversary. Thanks to Jimbojeow, I was able to see this piece in person.
Here’s a quick photo review of the watch. Photos are taken using my smartphone camera.
Here are some more pictures of another example that I saw at Big Time.
