Each clock has unique serial number on the rim of the case. People ask me if I get these from old subs. Nope, they come directly from the Vostok Clockworks that manufactured them for the Russian Navy, and now for the commercial market as well. So they are new, not used. In the four years that Sharper Image sold these , I understand they sold over 60,000, causing a parts crisis at Vostok.
Case is beige.
This face is a recent change, to take advantage of the popularity of the movie no doubt. Inside however, everything else is exactly the same as it has always been.
