The watch features a quartz movement with a mercury-in-glass movement regulator, a unidirectional rotating bezel, and a water-resistant case. The design is functional and robust, with a distinctive looks that reflects the watch's purpose.

The Sukelluskello was used by the Finnish military until the 1990s, where it was largely replaced by digital watches.
