Vintage 1976 Citizen Challenge Diver 62-6198 Serviced All Original
This is a stunning, possibly unworn Citizen Challenge Diver from May 1976, an icon of Citizen’s diving heritage. Produced as a direct competitor to Seiko’s legendary 6306/6309 “Turtle,” the Challenge Diver never reached the same production numbers or popularity at the time, which makes surviving examples in excellent condition extremely rare today.
