“The ETA2824-2 is the movement that watch industry insiders reach for when they want dependable Swiss automatic performance without reservation. In the Telamon it is paired with a case specification that professional divers recognise as genuine. 1000m water resistance with a helium escape valve is not a casual design decision — it is a statement that LONGIO built this watch for the depths, and priced it for the rest of us.”

— The Quiet Standard Editorial Team

Most dive watches are not built for diving. They carry the aesthetic vocabulary of the tool watch — the rotating bezel, the helium valve, the depth rating printed boldly on the dial — as decoration rather than specification. The LONGIO Telamon is not one of those watches. Its 1000m/3300ft water resistance rating is not a marketing figure. It is an engineering commitment, achieved through a case architecture that most brands never attempt at this price.

LONGIO named this watch after Telamon, the Argonaut who sailed with Jason in pursuit of the Golden Fleece. The mythology is earned. At 47mm across and 17mm thick, this is a watch built for serious use — substantial, purposeful, and entirely uninterested in pretending to be smaller than it is. On the wrist it reads with the quiet authority of something designed for conditions that most watches are simply not rated for.
