Seiko King Turtle Mod — sapphire & ceramic donor

The King Turtle takes the Turtle case and upgrades it from the factory: sapphire crystal instead of Hardlex, a ceramic instead of aluminium bezel, and often a textured wave-pattern dial. As a donor it saves exactly the upgrades you would otherwise retrofit on a standard Turtle.
