Vintage Seiko 6105-8110. This watch was Seiko's second diver's watch, released just shortly after the 62MAS. Because of this, this watch has earned the nickname of "Second Diver." However, this watch has a much more famous nickname. It is often referred to as the "Captain Willard" after Martin Sheen's character, Captain Ben Willard who wore this watch in the 1971 film "Apocalypse Now." 

Overall, this watch is in (B) very good condition. Minor scratches and scuffs can be seen on the case and bezel. The dial and crystal are both in good condition. The lume on the hands and minute markers have darkened with age. This watch has a genuine vintage Seiko GL-831 rubber strap. It is not the original strap to this watch, but was found on the next generation of Seiko divers, including the 6306 Turtles and "Arnie" Tuna watches.
