The name “Crystolon” was given to Citizen’s quartz watches in the 1970s, and various models.

This watch was produced as a professional diver’s watch that was water resistant to 150 meters.

Due to the popularity of Seiko Diver, Citizen’s diver watches are gradually beginning to attract attention.

The self-winding “Challenge Diver” is especially popular because of this anecdote.

“In 1983, CITIZEN’s automatic diver’s watch “Challenge Diver” was discovered at Long Reef Beach in Australia.
It was covered with barnacles when it was found at the bottom of the ocean, but to my surprise, the spring was wound by the waves and kept ticking.”

The automatic ones are moderately priced, but the quartz ones are not quite there yet and are in an affordable range.

The big feature of this watch is probably the large sword-shaped hour hand. While most of the hands are in the shape of mercedes or arrows, this shape has a great impact.

The case size is 42mm, but this is the value when measured up to the crown guard, so the actual size is about 40mm in bezel diameter.

It feels smaller than Seiko’s 7548 Diver, which is also 42mm.


The watch wast completely serviced before listing.

Battery and all gaskets are replaced in the service.

It comes with 6 months warranty.
