Citizen offers an impressive selection of well-respected dive watches, but none have a backstory as remarkable as the Promaster Fujitsubo.
In fact, few dive watches from any brand do.

Introduced in 2022, the Promaster Fujitsubo is an upgraded reproduction of Citizen’s Challenger Diver from 1977. It borrowed visual elements from the Rolex Submariner and Seiko 62MAS, but developed its own respectable reputation.
The Challenger Diver’s aquatic durability went down in horological history after one was found off the coast of Australia in 1983, still in working condition despite being covered in barnacles.
All the best tool watches have nicknames, and this legendary story earned the Challenger the moniker “Fujitsubo,” which means barnacle in Japanese.
