The Seiko Prospex "Save The Ocean Manta Ray Edition" King Turtle 200M Automatic Ref. SBDY063 is the second latest addition to the S.T.O “ King Turtle” collection in 2020, and with several upgrades that has been longing by collectors and enthusiasts. Prospex for Seiko basically means "Professional Specification" that their timepieces in this category are built with very high standards to be used by professionals. One of the most popular releases in recent years is probably the remake of the Seiko 6309 (circa 1976-1988) commonly known as the turtle. The original 6309 divers are pretty rare given its short 12 years production lifespan. Although there are many examples in the market, there are less than a dozen that are original. It is no wonder the new Prospex turtles are so popular among Seiko and dive watch collectors. And today we will dive into the details of the “crowned” Turtle that speaks of much refinement done to it.
